The importance of leading occupational safety and health (OSH) indicators in complementing lagging indicators
is an emerging topic for the promotion of a prevention culture in organizations. The purpose of this paper is to
describe the development process of a set of proactive leading indicators for safety, health and wellbeing (SHW)
at work, which was carried out as part of the International Social Security Association’s (ISSA) Vision Zero
strategy. Principles of integrated knowledge transfer and exchange between research, policy and practice were
followed in both the conception and development phases, and a mixed methods approach was applied across
four stages consisting of: a literature review and input from industry; a quantitative evaluation through an online
survey; a qualitative evaluation through feedback from organizational representatives and key stakeholders; and
a consensus building workshop with the ISSA Steering Committee. A set of fourteen indicators was developed to
complement the ISSA Vision Zero strategy, two in relation to each of its seven golden rules for promoting SHW at
work. The indicators deal with integrating each aspect of SHW in e.g. visible and competent leadership, pro-
curement, pre-work briefings, evaluating risk management and targeted programmes, learning from unplanned
events, innovation and change, work organization, onboarding and refresher training. Results can be presented
qualitatively and quantitatively as e.g. ‘yes’ or ‘no’ responses, on a Likert or continuum (five–point) scale, or with
frequencies and percentages. The indicators are designed for use by both small and large organizations across all
sectors, and can be used for benchmarking and as key performance indicators. They are not only intended to
better direct and control SHW processes, but also to support the development of a prevention culture.
Recommendations are provided on how the indicators can be refined and improved through future research.
1. Introduction
‘Vision Zero’ (VZ) at work is a transformational approach to pre-
vention that integrates the three aspects of safety, health and well-being
(SHW). It is based on the assumption that all accidents, harm and work-
related ill-health are preventable. VZ is the ambition and commitment
to create and ensure safe and healthy work and to prevent all accidents,
harm and work-related diseases in order to achieve excellence in SHW.
VZ should be understood as a journey, a process towards the ideal. It is
also a value-based vision implying that work should not negatively
affect workers’ SHW, and if possible, should help them maintain or
improve their SHW and develop their self-confidence, competences and
employability (Zwetsloot
et al., 2017b).
VZ is regarded as a commit-
ment strategy (Zwetsloot
et al., 2013a; Zwetsloot et al., 2017a),
which
implies that the process of continual improvement is driven by the
commitment of both (top) leaders and workers. In the implementation
of VZ commitment, communication, culture, and learning, are key as-
pects (Zwetsloot
et al., 2017a).
A commitment strategy can start at any
level of SHW performance, and trigger a continual improvement pro-
cess. This implies that VZ is relevant for a large variety of organizations
(not only for the well-known frontrunners, but also for small organi-
zations).
This paper describes the development of a set of proactive leading
indicators for SHW for the International Social Security Association
(ISSA). ISSA and its fourteen sections for prevention launched their VZ
strategy and the ISSA Global VZ Campaign in September 2017 at the
XXI World Congress on Safety and Health at Work in Singapore. The
strategy and campaign are run by ISSA partners in more than 80

countries, and by the spring of 2020 more than 11,000 organizations
had associated themselves with the VZ campaign, as did more than
1000 trainers (Treichel,
2020).
ISSA’s VZ concept incorporates seven
‘Golden Rules’ for prevention (ISSA,
2017).
The concept is flexible, and
can be adjusted to the specific SHW priorities for prevention in any
given context.
Collaboration between organizations, companies and researchers in
the research process has shown to be conducive to integrated knowl-
edge transfer and exchange (KTE) in promoting occupational safety and
health (OSH) (Van
Eerd, 2019; Van Eerd & Saunders, 2017).
The de-
velopment of the proactive leading indicators described in this paper
reflects this integrated KTE process, as it was carried out in response to
suggestions from, and in collaboration with companies and other or-
ganizations that have associated themselves with the ISSA VZ strategy.
They suggested the development of a common set of leading indicators
in order to be able to benchmark globally and organize mutual learning.
For ISSA it was important that the indicators are not only theoretically
sound, but that they are recognized as useful by many organizations
participating in their VZ strategy. This implies that the user friendliness
of the indicators was considered from the start as an important condi-
tion. The seven Golden Rules (ISSA,
2017)
formed the framework for
the indicators, with two indicators being developed for each Golden
Rule.
The focus was on developing indicators that were both ‘proactive’
and ‘leading’, recognizing that current indicators of SHW at work are
often reactive, and do not provide directions for improvement e.g. ac-
cidents, injuries, sickness absence, and ill health. Leading indicators
that are used by organizations are often related to aspects of good OSH
management and are in line with ISO 45,001 (ISO,
2018),
e.g. the time
needed to close improvement actions or non-compliances. Proactive
management of SHW requires new types of performance indicators,
with an emphasis on proactive or primary prevention. However, there is
currently no broadly accepted set of SHW leading indicators, and as a
result, proactive companies often define their own sets of leading in-
dicators. The variety of indicators used in practice hinders bench-
marking and mutual learning.
Furthermore, it was recognized that most organizational practices
tend to focus more on safety and to some extent health aspects, with
less focus on wellbeing at work. Additionally, attention to work-related
health and wellbeing is often limited to hazards and associated risks
that stem, like safety risks, predominantly from technology-related as-
pects of production processes, such as the design of technical installa-
tions and workplaces. Often there is less organizational and systematic
attention paid to health compared to safety, while psychosocial risks
and wellbeing at work often remain out of scope (Bergh
et al., 2014b;
Leka et al., 2015).
However, SHW have more in common than many would expect
(Zwetsloot
et al., 2017b).
SHW represent similar human and social
values, and each is based on valuing people. There are also common
‘supporting values’ that are relevant for all three aspects (Zwetsloot
et al., 2013b; Zwetsloot, 2019),
e.g. trust is important for wellbeing,
and it is important for a culture wherein people feel free to report in-
cidents and near misses, or which address the health problems they may
encounter. Being ‘fit for work’ physically and mentally is important for
managing safety. In both areas, the following issues are important: (1)
design and management challenges; (2) control of (work) processes and
dealing with deviations; (3) improving accuracy and human behavior;
and (4) proactive approaches to new developments, including re-
organizations and outsourcing, increasing flexibility, job insecurity, etc.
From the perspective of credibility for the employees, SHW are also
closely associated. Credibility, taking care of the safety of people, im-
plies that people (and their health and wellbeing) are valued. Several
concepts and models that have been developed and are based on con-
siderable evidence in one area, also seem relevant for the other area, for
example, on job design and work organization (Leka
et al., 2008)
versus
management systems, increasing risk awareness and safety culture
2
(Clarke,
2006; Edwards et al., 2013).
There is increasing recognition in research and in practice of the
need to overcome sub-optimizations of SHW and develop approaches
and models that support the integration of the various specialist views
on SHW (Jain
et al., 2018).
There is also a need to effectively combine
traditional OSH and workplace health promotion (NIOSH,
2020; Jain
et al., 2018).
The development of the set of proactive leading indicators
for SHW aims to provide organizations with a promising tool to mea-
sure the degree of proactivity of their SHW actions. The tool could
provide organizations with feedback on the strengths and weaknesses in
their efforts, which is useful for the process of continual improvement.
In addition, the indicators can also facilitate internal and external
benchmarking. In this way organizations will be able to put in place
good practices that support the promotion of all three aspects of SHW in
an integrative way, and as an integrated part of the business processes.
At the same time, it is recognized that a full integration of SHW is likely
to undervalue the importance of the health and wellbeing aspects if
organizational focus has traditionally been on safety (Zwetsloot,
1994).
It is therefore just as important that the indicators can differentiate
between the three aspects of SHW.
Before the development process of the proactive leading indicators
is outlined in detail, it is important to first consider the use of OSH
indicators, including the key concepts of leading and lagging indicators,
and the research and evidence base in this area.
1.1. The use of occupational safety and health indicators
OSH indicators should comprise condensed information on existing
and emerging risks, exposures, hazards, as well as on preventive ac-
tivities to (further) reduce the remaining hazards and risks (Alruqi
&
Hallowell, 2019).
At the same time, the data thus obtained should be
useful for evidence-based decision making. Proactive leading indicators
for SHW reflect the actionable, current and ongoing processes, activities
and performances that are doing more than merely controlling existing
risks and safeguarding the status quo, but focus on recognizing,
creating, using and evaluating opportunities for continual improve-
ment, both specific short term improvements and the process of con-
tinual improvement. In this way they have a great potential to generate
impact, both in the short and long term.
The performance indicators most frequently used by organizations
reflect the OSH performance of the past (e.g. number of accidents and
occupational diseases, lost time incidents or sickness absence). These
have been called ‘lagging indicators’, because the information is lagging
behind reality. They measure the ‘outcomes’ of the past OSH manage-
ment process, rather than the qualities of the presently existing OSH
management and leadership processes. ‘Leading indicators’ are com-
plementary to lagging indicators; and have predictive value; they are
valuable for improving SHW management and leadership, e.g. by in-
tervening in risky situations before safety or health is affected (Jain
et al., 2018).
Leading indicators have been classified as active or passive
indicators (Hinze
et al., 2013).
Passive leading indicators are typically
implemented before work begins and remain relatively static once a
project has begun, e.g. number of workers with a specific certification.
In contrast, active leading indicators can be readily changed during
work, e.g. pre-task planning meetings. These indicators are generally
continuous in that they occur at a frequency or are measures of quality
of implementation. However, not all leading indicators are by defini-
tion, ‘proactive’ leading indicators as defined above.
Using the bowtie metaphor,
Swuste et al. (2016)
provided a dis-
tinction for leading and lagging indicators, with leading indicators
providing information on the left-hand side of the central event, and the
lagging indicators on the right-hand side. Thus, leading indicators ba-
sically are proxies for hazards, for barriers, for scenarios and manage-
ment factors, while lagging indicators are proxies of the central event,
of 'loss of control' and of consequences (Grabowski
et al., 2007; Øien
et al., 2011).
According to this approach, leading indicators provide

information on distortions of processes, and thus on the stability of a
system. Furthermore, being achievable, meaningful, transparent, easy
to communicate, valid, useful, and timely were identified as some of the
valuable qualities of leading metrics. But perhaps most importantly,
leading indicators should be actionable, that is, they can be utilized to
identify and implement steps intended to reduce or eliminate risk
(Sinelnikov
et al., 2013).
It should also be highlighted that both in the literature and in
practice, there are blurry delineations among OSH risk analysis, safety
climate, and leading indicators, and it has been highlighted that the
differences between these concepts might be merely theoretical and
ideological (Alruqi
& Hallowell, 2019).
Due to this ambiguity, a more
general terminology has also been suggested, such as key indicator,
performance indicator, or key performance indicator (Eriksen,
2009;
Grote, 2009; Guldenmund & Booster, 2005; Mearns, 2009; Øien et al.,
2011; Saqib & Siddiqi, 2008).
Some authors prefer the term ‘positive
indicators’ to leading indicators (e.g.
Podgórski, 2015),
while the
OECD
(2008)
uses the term ‘activities indicators’ to refer to (proactive)
leading indicators, and ‘results indicators’ for lagging indicators. What
is important to highlight is that irrespective of the term used, these
concepts aim at developing a prevention culture (Bollman
& Boustras,
2020; Kim et al., 2006).
The appeal of leading metrics is in their potential to predict and
prevent adverse outcomes by giving organizational leaders an addi-
tional set of forward-looking OSH targets for improvement.
Organizations also use leading metrics to support communication and
employee morale building strategies aimed at transforming organiza-
tional culture from being passive and problem focused to being
proactive and solution driven. A meta-analysis by
Alruqi and Hallowell
(2019)
highlighted that nine common leading indicators are sig-
nificantly correlated with worksite injuries: safety record, safety re-
source, staffing for safety, owner/leader involvement, safety training/
orientation, personal protective equipment, safety incentives program,
safety inspections/observations and evaluations, and pre-task safety
meetings. The authors concluded that that these indicators are valid
and generalizable across geographies, industry sectors, company types,
and safety cultures.
While some recent research has shown that some safety leading
indicators are predictive (Salas
& Hallowell, 2016),
provide early
warnings of potential hazards (Guo
& Yiu, 2015),
and can be used as
levers to improve future performance (Lingard
et al., 2017),
there is still
limited scientific evidence currently available to indicate which leading
indicators for OSH promotion should be used (Amick
& Saunders,
2013). Hallowell et al. (2013)
identified 13 proactive safety indicators
that improve safety performance, including: near-miss reporting, safety
observation, auditing program, pre-task safety meeting, housekeeping
program, and worker involvement. Later, in a study of 261 contractors,
Salas and Hallowell (2016)
found evidence that empirically supported
the following as predictive of improving safety performance: near-miss
reporting, stop-work authority, upper-management engagement in
safety activities, worker involvement, owner involvement, safety au-
diting and observation, and safety risk assessment.
Another prominent example for leading indicators developed in the
area of OSH comes from the Ontario Leading Indicators Project, which
the Canadian Institute for Work & Health has been running since 2008.
The Organizational Performance Metric–Monash University (OPM-MU)
has been reported to be a reliable and valid measure of leading in-
dicators in OSH (Shea
et al., 2016),
and useful for not only safety but
also health outcomes (Amick
& Saunders, 2013).
The OPM-MU has
been associated with fewer incidents and fewer near misses. Aggregated
OPM-MU scores have also been associated with lost-time and medical-
treatment injury rates (De
Cieri et al., 2016).
This tool is similar to the
Prevention Culture Index developed by IOSH-UK which consists of 10
indicators: management commitment and visibility; communication
including feedback loops; productivity versus safety; information, in-
struction and training; safety resources; participation; shared
3
perceptions about safety and risk; trust; autonomy; incentives; and re-
porting accidents and near misses, investigations and controls (White,
2015).
In 2015, an online survey was conducted to explore whether the
indicators included in the IOSH Prevention Culture Index are suitable
for measuring a culture of prevention at company level. The survey was
sent to senior OSH practitioners who are members of IOSH, of whom
840 completed the survey. The survey asked respondents to assess the
importance of the indicators for an effective prevention culture and
whether the proposed options are the right ones for measuring a culture
of prevention. It also asked whether the maturity model is suitable for
making statements regarding how each indicator contributes to im-
proving the culture of prevention. The indicators rated as being the
most effective were: management commitment and visibility, commu-
nication, and participation. The indicators rated as being the least ef-
fective were: safety resources (PPE available, posters etc.), productivity
versus safety (time and pressure), and reporting (accidents and near
misses, investigations and controls) (White,
2015).
Leading indicators for wellbeing at work have also been developed
in the area of occupational health psychology. For instance, Bergh and
colleagues developed a leading indicator for psychosocial risk (PRI) in
the oil and gas industry, consisting of a condensed set of 11 items,
addressing job demands, role clarity, relationships, job control and
support (Bergh
et al., 2014b).
The PRI has been shown to effectively
predict both near misses in terms of safety (hydrocarbon leaks) (Bergh
et al., 2014a),
and well-being at work (Bergh
et al., 2018).
The literature on leading indicators also indicates some challenges
in their development: conceptual clarity, whether to measure work-
place policies and practices through self-assessment or external audit,
how to interpret changes in scores, how to use indicators to improve
prevention, and how much to tailor indicators to specific workplace
contexts (Amick
& Saunders, 2013).
There is also little consensus on
which methods should be used for identifying leading indicators (Raben
et al., 2018).
Another issue being discussed is whether there can be a
common set of leading indicators at a “high level” across industries and
organizational contexts within a country or internationally (Shea
et al.,
2016).
Recognizing these challenges, we adopted a mixed methods ap-
proach for the development of the proactive leading indicators for
SHW, with stakeholder input and feedback throughout the KTE devel-
opment process. The aim of this paper is to describe this development
process which was implemented in four stages as detailed next.
2. Method
A mixed methods approach was applied for the indicator develop-
ment process that included four stages: (1) a review of literature and
input from industry; (2) a quantitative evaluation of a draft set of in-
dicators through an online survey; (3) a qualitative evaluation through
feedback from organizational representatives and key stakeholders; and
(4) a consensus building workshop with the ISSA Steering Committee.
2.1. Stage 1: Review of literature and industry input
First, a literature review of the academic and grey literature was
conducted on OSH/SHW indicators with a specific focus on leading
indicators. The literature review process began with seeking familiar-
ization with the range and diversity of data in this domain, and gaining
an overview of the body of material gathered to be reviewed. This was
primarily achieved through running preliminary searches of the (aca-
demic and grey) literature, and by sifting and sorting through identified
sources of information. The following search terms were used:
a. Indicator OR measure OR benchmark OR precursor
AND
b. Leading OR lagging OR proactive OR positive performance OR key
performance

Our systematic search of databases, Pubmed and Web of Science,
provided 5218 hits. A search on Google Scholar provided 18,000 hits –
and we took the first 150 (to get 100 unique hits, removing doubles)
which were ranked by Google by ‘relevance’. After reviewing the ab-
stracts of these publications for relevance and avoiding duplication, 92
publications were included in our final literature database. The review
focused primarily on studies published between 2014 and 2019.
However, earlier studies were also reviewed with 17 of the 92 studies
being from pre-2014. Most studies were published in the journal Safety
Science (nearly 25%).
At the same time, input on SHW indicators and practical evidence
was sought by organizations participating in ISSA’s VZ network and the
business networks of the researchers. Input was received from 32 or-
ganizations and experts from a variety of countries (9 Germany, 6 the
Netherlands, 4 Finland, 3 Japan, 2 international, 1 Chile, 1 Costa Rica,
1 France, 1 Mexico, 1 Russia, 1 Switzerland, 1 UK, 1 Ukraine) and
sectors (e.g. automotive, chemical industry, construction, electrical
power, engineering, food processing, manufacturing, mining, and
trade).
The first step was to identify what we regarded as a leading in-
dicator. Both in the literature and from the input received, several re-
ferred to what we regarded as ‘good practices’ (e.g. exemplary behavior
of leaders). We did not regard these as useful indicators, as these factors
are not easy to measure quantitatively, and therefore are less useful for
benchmarking. Such factors were therefore regarded by the project
team as ‘indications’, not as potentially relevant leading indicators.
We then reviewed, evaluated and synthesized the collected litera-
ture and industry input in an integrative way in order to identify the
focus and content of the identified indicators, and cluster them ac-
cording to the ISSA Golden Rule they were most closely associated with.
In the case where the indicators were relevant to more than one Golden
Rule, the authors clustered them by consensus according to the most
relevant Golden Rule.
In discussion with ISSA, six core criteria for the selection of proac-
tive leading indicators were applied, as well as six complementary
criteria. Each individual indicator had to fulfil the core criteria; the
complementary criteria were mainly relevant for a well-balanced set of
14 indicators (see
Table 1).
The four authors of this paper individually ranked each of the
identified indicators in terms of the core criteria, of which a comparison
of rankings indicated a high degree of agreement (80%). As a result,
two candidate proactive indicators were identified for each Golden
Rule. One proactive leading indicator was then selected for each of the
Golden Rules for the next stage: developing an associated factsheet, and
including the indicator /factsheets in the pilot.
2.2. Stage 2: Quantitative evaluation
The next stage in the indicator development process was piloting the
indicators through an online survey. A factsheet was first developed per
indicator, with condensed information on one A4 page regarding: key
concepts, aims, how to measure, limitations, and five good practices.
The good practices were included to ensure a qualitative understanding
in addition to the quantitative targets included in the factsheets
(Oswald,
2020).
After discussion with the ISSA Steering Committee a
rating of the outcomes was added, with three options: excellent, on the
way to excellent, and needs improvement. The idea behind this was
ISSA’s desire to trigger organizations to aspire to the qualification 'ex-
cellent'. The seven indicators that were included in the pilot are shown
in
Table 3.
The online pilot survey was conducted between September and the
first week of December 2019. A website was developed where partici-
pants could access the survey that was hosted on Qualtrics. Information
on the pilot was disseminated through ISSA to their VZ network of
organizations and through the researchers to their business networks.
Participants were asked to provide feedback to the following questions
for each of the seven indicators:
1. Is this indicator relevant for your organization?
2. Is the indicator clearly understandable? If No/Not sure, why?
3. Does the factsheet provide clarity around the indicator’s: Aim? Use?
Good practices?
4. Is this indicator helpful to your organization as a part of your Vision
Zero strategy? If No/Not sure, why?
Descriptive analyses of the survey findings are presented in the
Results section. Additional open-ended questions were also included
where participants could provide further feedback on each indicator
and the set of indicators overall.
2.3. Stage 3: Qualitative evaluation
A qualitative evaluation of the indicators was conducted through
the open-ended questions included in the online survey as well as
feedback provided by key stakeholders and the ISSA Steering
Committee and organizational representatives. It also involved discus-
sions at international conferences such as: Working on Safety (Austria,
September 2019), APA/NIOSH Work Stress and Health (USA,

November 2019), Vision Zero Summit (Finland, November 2019), and
various ISSA network meetings.
Several interested organizations and individuals emailed more
comprehensive feedback directly to the project leader, e.g. the
Institution of Occupational Safety and Health (IOSH), The British Safety
Council, the (Canadian) Institute of Work & Health, the American
Industrial Hygiene Association (AIHA), and various organizations (e.g.
Siemens). The feedback was documented and thematic analysis (Braun
& Clarke, 2006)
was conducted on all qualitative input.
2.4. Stage 4: Consensus-building workshop
The final stage in the development process involved a consensus-
building workshop with the ISSA Steering Committee in January 2020.
Six participants represented five ISSA sections for prevention:
Electricity, Information for prevention, Mining, Transport and Trade.
Consensus was reached on the following:
was to be explored further.
It was also agreed that it would be useful to provide guidance to
organizations that may begin with a limited set of indicators, de-
pending on their OSH situations and ambitions.
3. Results
3.1. Stage 1: Literature and industry input review findings
Table 2
presents a summary of the literature and industry input
review findings. Sixty-four leading indicators were identified in the
literature, and 72 in the input provided by industry. As shown, fewer
indicators were identified under ISSA’s Golden Rule 5, both through the
literature and the industry input. Several additional success factors
were identified; 39 in the literature review and 94 through industry
input. These were not taken into consideration further, as they were not
easy to measure quantitatively, and therefore were less useful for
benchmarking.
The next step was the selection of a draft set of seven proactive
leading indicators (Table
3).
An accompanying factsheet was developed
for each of these indicators, which then formed the input for the online
survey in stage 2.
3.2. Stage 2: Online survey results
Sixty organizations participated in the online survey, representing a
wide variety of sectors, and the majority of them were large (75%, with
250+ employees). The organizations operated in various countries,
while twenty were multinational. Eight organizations came from
Germany and seven from the UK, four each from the USA and Denmark,
three from Norway, and two each from the Netherlands and Poland -
thus the majority came from Europe. Most of the respondents were in-
company SHW professionals. A high drop-out of participants affected
the survey, with 60 responses received in relation to questions on the
first factsheet, and only 34 responses received on the last factsheet.
Table 4
presents an overview of the responses to the survey in relation
to the questions asked for each indicator.
The majority of respondents found the indicators to be clearly un-
derstandable and relevant for their organization. They also thought that
A ‘Guidance document’ for the leading indicators should be devel-
oped to accompany the factsheets. It should include ‘how to use the
leading indicators both for high-level companies and for those
starting with a VZ strategy. It should include suggestions on where
to start, in case using all indicators may not be relevant or be too
difficult, and to provide guidance on how to present the outcomes of
using the indicators.
It was emphasized that the overwhelming majority of organizations
are small companies. Therefore, it was important to make the use of
the indicators as simple as possible for small organizations. This
would require differentiation in the options for using the indicators
(measurement options).
In line with the previous point, the titles of the indicators should be
short (preferably no more than three words) and to the point.
The factsheets should be made more attractive for smaller compa-
nies as well. They should start with the aims, while sections on
measurement should be moved to the end of the factsheets. The
ratings should move to the associated Guide. The ratings should
imply a possibility and trigger each company, also ‘beginners’, to go
to the next level. Suggestions to distinguish five development levels
were already received through organizational feedback, and this

the indicator factsheets overall provided clarity around their use and
good practices, and would be a helpful tool as part of their VZ Strategy.
3.3. Stage 3: Qualitative findings
The qualitative feedback received through the open-ended questions
included in the survey, key stakeholders from the ISSA Steering
Committee, and organizational representatives was analyzed themati-
cally, and the key issues (themes) that emerged are presented below.
Clarity
The majority of respondents highlighted the need for simplicity in
presenting and describing the indicators, in terms of short, clear titles,
definitions, use of examples, and measurement. They suggested looking
for ways to further simplify the factsheets.
In relation to indicator 2.1, some respondents mentioned that the target
of this indicator was unclear. It was suggested that it should more clearly
apply the hierarchy of controls. Furthermore, it was suggested that indicator
4.1 did not seem to trigger clear improvement actions the way it was pre-
sented. As one participant stated in relation to indicator 4.1:
“My company has “simplicity” as a value and having an indicator on
indicators is not compatible with this value” (medium sized orga-
nization).
Relevance to smaller organizations
Some participants from smaller organizations found the indicators
to be too high level for them. For example, in relation to indicator 2.1,
they felt it was not practical for a small company and highlighted the
need for some examples. The majority of respondents from smaller
organization found indicator 4.1 on SHW Key Performance Indicators
(KPIs) to be too general and not useful in their context.
For indicator 6.1 it was suggested that it is hard to do all training
before the start of a job. Therefore, this indicator is likely to be dis-
couraging, particularly for smaller organizations. As one respondent
from a small organization put it:
“I feel this has been developed for middle- to large-sized businesses
or organizations. My business (a shop with 6 part-time sales per-
sonnel, including 3 students) would require a severely scaled down
version for it to be practical and, more importantly, used. SHW of
my staff and customers is of high importance to me, but for a
business of my size, this document is too dense. One size doesn’t fit
all” (small organization).
The user friendliness for smaller organizations was also a concern of
the ISSA Steering Committee, as SMEs are an important target group for
the ISSA members (mainly national social security agencies).
Measurement
The majority of participants highlighted the need for more examples
in relation to measurement. For example, in relation to indicator 1.1, it
was suggested that the indicator would require much effort to measure.
6
It was also suggested that pre-work SHW meeting quality is difficult to
measure. While the majority of respondents found indicator 5.1 re-
levant for their organization, some respondents thought that there were
three entirely different entities combined into one topic, which would
complicate measurement in practice. The measurement ratings were
thought to be too ambitious in some cases:
“I would suggest to give some more thought on ratings for mea-
surements, e.g. ‘Excellent’ 95%, ‘On the way to excellent’ 80% to
94%, ‘Needs improvement’ less than 80%. For most enterprises even
80% is for them a fantastic result. It would be reasonable to make
the scale lower, but in several years, with the growth of maturity,
the scale can be proposed higher. This is something to consider”
(large organization).”
Finally, it was suggested that an overview diagram for all indicators
would be useful to include that would enable organizations to trace
progress.
Prioritization
A final key issue that emerged was around prioritization of the in-
dicators. Many participants suggested that it might be difficult for or-
ganizations to find time to measure all the indicators. The possibility of
ranking or prioritization of the indicators was highlighted in relation to
those that would achieve most impact with fewest resources:
“Is it possible to make a priority order in relation to what will
contribute with most impact and less resources? If you don't have
the possibility to mobilize resources for all seven….it would be nice
to see some specific examples of how this could work as well” (large
organization).
Some respondents suggested that organizations could choose the
indicators that were most suitable to them. Finally, it was reported that
it may be a challenge for all indicators to include all three aspects of
safety, health and wellbeing, as maturity may be different across or-
ganizations, and as responsibility for developing them, training and
follow-up lies within different functions of the organization, e.g. human
resources with a focus on health and wellbeing.
3.4. Stage 4: Consensus building: Proactive leading indicators for safety,
health and wellbeing
The feedback and issues raised during the pilot were discussed at
the consensus building workshop with the ISSA Steering Committee.
Several changes were implemented to the first seven indicator drafts
and associated factsheets, as well as the seven additional indicators and
factsheets that were developed.
Clarity:
The titles of the indicators were simplified (shortened) - the
measurement scales (frequencies or percentages) were not included in
the title anymore. Indicator 4.1 ‘The number of leading SHW KPIs’, was
replaced by another indicator where relevance to SHW was more direct.
The indicator ‘Frequency of pre-work meetings’ was moved to Golden

Safety Science 130 (2020) 104890
Rule 4, as its relationship with leadership was rather indirect.
Relevance to smaller organizations:
To increase the relevance for
smaller organizations and make the (set of) indicators more user-
friendly, the following changes were made: the factsheets were rede-
signed, whereby the ‘how to measure’ box (regarded as the greatest
bottleneck for small organizations) was transferred to the bottom of the
factsheet; and two simpler options for ‘how to measure’, in particular a
qualitative Yes’ or ‘No’ option, were introduced.
Measurement:
The ‘how to measure’ section in the pilot test ex-
plained how to measure the indicator quantitatively. Two simpler
modes of using the indicators were introduced. As a result, for each
proactive leading indicator three options for measurement are given:
qualitative, semi-quantitative, and quantitative. The qualitative mea-
surement option (‘Yes’ or ‘No’) is simple and user friendly; it can be
useful for any organization, also for small organizations. The semi-
quantitative option (a five–point scale from ‘Always’ to ‘Never’) makes
it easier for medium-sized organizations to measure and benchmark,
while the third option retained the frequency and percentage calcula-
tions. For example, in relation to indicator 7.2 Investing in people –
motivate by participation: Recognition and reward, the following op-
tions are available:
Option 1: Are workers given recognition for excellent SHW perfor-
mance? (Yes/No)
Option 2: How often are workers given recognition for excellent
SHW performance?
(Always or almost always, Frequently, Occasionally, Rarely, Never
or very rarely)
Option 3: Determine the number of identified cases of excellent
SHW performance, and calculate what percentage were recognized
in the past 12 months.
Each measurement option can be used to differentiate five levels of
organizational performance: Starting, Learning, Progressing, Advancing
and Achieving. Results can be derived on a monthly basis, so as to be
able to use them proactively, and allow for follow-up and learning in a
timely manner. Monthly trends for an indicator can be plotted over the
last twelve months, and summary results for the indicators in each of
the seven Golden Rules can be plotted in e.g. a radar diagram.
Prioritization:
A Guide was developed that provided more explana-
tion and useful background of the set of indicators and guidance for the
users. In the Guide a description is provided of why it may not be ne-
cessary to use the full set of indicators. Examples are given of how to
tailor the set of indicators to a number of organizational contexts, and
how to prioritize the indicators.

shows the final set of the ISSA proactive leading indicators
for SHW at work.
4. Discussion
The multi-stage mixed-methods approach that was implemented for
the development of the proactive leading indicators, balancing the use
of evidence with usability and knowledge transfer, has previously been
highlighted as good practice in the literature. To provide practical re-
commendations for the formation of a leading indicator program
Guo
and Yiu (2015)
presented a model for developing leading indicators
based on four major steps: define the system and analysis level (con-
ceptualization), include only measurable constructs (operationaliza-
tion), develop leading indicators (indicator generation), and validate
selected leading indicators (validation and revision). In this study, these
four steps were followed to develop a set of leading indicators for SHW
which can be used by enterprises implementing Vision Zero. The de-
velopment process began with a discussion on the varying con-
ceptualizations of leading SHW indicators identified in the literature
7
and by practitioners in industry, which was used to operationalize and
generate a set of indicators across ISSA’s seven golden rules. In stages 2
and 3 of the study the indicators were validated, and then revised in
stage 4 to develop the final set of 14 proactive leading indicators for
SHW. Likewise, the set of proactive indicators fulfil the qualities iden-
tified by
Sinelnikov et al. (2013),
being achievable, meaningful,
transparent, easy to communicate, valid, useful, timely and actionable.
Furthermore, in line with
Alruqi and Hallowell (2019)
the indicators
include a focus on resources, leadership, training, rewards, preventive
actions, evaluations and pre-task meetings.
It should also be noted that the indicators are interrelated, and al-
though they have been associated with specific ISSA golden rules, many
of the indicators will in practice have an effect on more than one golden
rule. For example, indicator ‘4.1 Pre-work briefings’ can have a positive
effect on ‘Rule 1 Taking leadership – demonstrating commitment’, ‘Rule
2 Identifying hazards and controlling risks’, ‘Rule 6 Improve qualifi-
cations – develop competence’, and ‘Rule 7 Investing in people – mo-
tivating by participation’.
In terms of their proactivity, there seem to be at least five relevant
mechanisms that make leading indicators work. The first is that in-
dicators should support a commitment strategy or the development of a
prevention culture. Examples include visible leadership commitment to
SHW, suggestions for improving SHW, and recognition of excellent
SHW performance (indicators 1.1, 7.1 and 7.2). Furthermore, indicators
should stimulate subsequent SHW prevention right at the start of any
process or activity. Competent leadership and integrating SHW in job
induction, organization of work, innovation, procurement and training
(indicators 1.2, 3.1, 4.2, 5.1, 5.2 and 6.1 respectively) are examples of
such indicators. It is also important that indicators stimulate early ac-
tive anticipation. Such indicator examples include learning from un-
planned events and integrating SHW in pre-work briefings (indicators
2.2 and 4.1). They should support processes for organizational learning
and continual improvement (e.g. evaluating risk management and
evaluating targeted programmes (indicators 2.1 and 3.2). Finally, they
should facilitate the translation from planning to implementation, e.g.
though refresher training (indicator 6.2).
KTE is a process of “making relevant research information available
and accessible for use in practice or policy” (Van
Eerd & Saunders,
2017, p.1).
The applied integrated KTE process (Van
Eerd, 2019; Van
Eerd & Saunders, 2017)
in this study proved fruitful whereby ISSA,
organizations, companies and researchers were all actively engaged in
the conceptual phase and all four research stages of the project. The
request from organizations involved in ISSA’s VZ strategy triggered the
initiation of the research project. In all stages of the project, the ISSA
sections for prevention were actively involved by providing critical
feedback and stimulating associated organizations to also provide input
(in terms of sharing indicators and practical evidence, and participating
in the online survey and qualitative evaluation). The KTE process is still
underway, with ISSA and its various industrial sectors taking respon-
sibility for the initial global dissemination of the indicators and the
accompanying guide, thus contributing to making the research in-
formation available and accessible for use in policy and practice.
The development of the proactive leading indicators for SHW that
can be a common set of leading indicators at a ’high level’ across in-
dustries and organizational contexts internationally (Shea
et al., 2016)
was ambitious in various ways. The development process addressed
issues relating to conceptual clarity, measurement, interpretation of
results, and applicability of indicators to specific workplace contexts
(Amick
& Saunders, 2013).
Applicability for all areas of safety, health
and wellbeing was one of the key criteria that were used in their de-
velopment. This created the dilemma of integration versus separate
measurement. Conceptual integration in terms of the same indicator
being used for all areas was maintained in the developed indicators, to
ensure they become an integrated part of business processes. However,
it is advised that measurement addresses the three aspects separately to
ensure that health and wellbeing are prioritized in the same way that

Table 5
International Social Security Association’s (ISSA) proactive leading indicators for safety, health and wellbeing (SHW) at work.
Rule No. 1: Take leadership – demonstrate commitment
Indicator No. 1.1
Visible leadership commitment
Indicator No. 1.2
Competent leadership
Through visible leadership commitment and being exemplary role models, leaders demonstrate their commitment to SHW, and actively
promote and support SHW improvement processes and the development of a prevention culture.
Committed and competent SHW leadership is essential to drive the development processes of VISION ZERO. Such leaders are intrinsically
motivated to improve SHW and promote SHW as personal and organizational core values. Leaders then regard SHW as integrated parts of
business processes, and support processes of continual improvement of SHW, while creating a strong prevention culture.
Rule No. 2: Identify hazards – control risks
Indicator No. 2.1
Evaluating risk management
Indicator No. 2.2
Learning from unplanned events
Evaluation of the effectiveness of SHW risk management shows leadership focus and commitment to improving SHW, and stimulates
active participation and influence of workers. It allows leaders and workers to improve the effectiveness and sustainability of SHW
promotion measures as an integrated part of business. In addition, it allows for organizational learning and continuous development.
Learning from unplanned events (incidents, events, cases) is necessary to prevent similar undesirable events from reoccurring, and to
create a culture of SHW prevention and learning. Adequate follow-up of reported unplanned events will increase reporting and learning.
Rule No. 3: Define targets – develop programmes
Indicator No. 3.1
Workplace and job inductions
Indicator No. 3.2
Evaluating targeted programmes
Integrating SHW in induction (on-boarding) processes demonstrates that SHW are an integrated part of each job and each business
process. SHW are an essential part of leaders’ and workers’ new job in a workplace. It can be both a formal and informal way of
welcoming new personnel to an organization, group and/or job function, and highlights SHW purpose, values and goals.
Evaluating targeted programmes (e.g. temporary campaigns) that integrate SHW in work processes helps to verify that they are
implemented as intended, and that the improvement goals for SHW are met.
Rule No. 4: Ensure a safe and healthy system – be well organized
Indicator No. 4.1
Pre-work briefings
Indicator No. 4.2
Planning and organization of work
Integrating SHW in pre-work briefings allows leaders and workers to identify context specific hazards, risks and prevention measures.
This shows leadership focus and commitment to SHW, and a commitment to stimulating the active participation and influence of workers.
Planning and organization of work are essential for the success of every organization and for ensuring SHW. This is because planning can
make an organization competitive and efficient. Several issues need to be considered in effective planning and work organization in order
to promote SHW. Good planning and work organization promote good morale and a healthy organizational culture.
Rule No. 5: Ensure SHW in machines, equipment and workplaces
Indicator No. 5.1
Innovation and change
Indicator No. 5.2
Procurement
Technological, organizational and personnel changes occur frequently in organizations. Instead of assessing SHW risk after the changes,
these changes should be considered proactively, and to utilize innovation to improve SHW right from the start in the design phase.
The indicator aims to trigger the systematic use of procurement for SHW improvement. Procurement, particularly of hardware, can
determine SHW risks for a long period, while procurement of services such as maintenance, is often associated with increased SHW risks.
Rule No. 6: Improve qualifications - develop competence
Indicator No. 6.1
Initial training
Indicator No. 6.2
Refresher training
Competence is key to ensuring good SHW. Being proactive requires training/qualifying leaders and workers in advance, before they start
their job. It also shows that no job or task should be carried out without the relevant SHW competences, and that SHW are an integrated
part of any job or profession.
Developing SHW competence should be an aspect of continuous professional development. Refresher training ensures that leaders and
workers’ knowledge and skills on SHW remain up to date and include new SHW insights.
Rule No. 7: Invest in people – motivate by participation
Indicator No. 7.1
Suggestions for improvement
Indicator No. 7.2
Recognition and reward
In the development of a prevention culture and the active involvement of workers, it is important that suggestions of workers for SHW
improvements are welcomed and are taken seriously. This will stimulate workers’ active commitment to SHW and demonstrates their
leaders’ commitment to improving SHW.
Providing timely, proactive and relevant recognition and reward for excellent SHW performance to both leaders and workers is essential
for fostering a SHW culture that is based on trust, respect, participation and cooperation.
safety issues are. In many industries there is the tradition of managing
safety, but much less a similar tradition in managing health and well-
being. The indicators developed are explicitly meant to support all
three SHW aspects, both individually and jointly. The indicators may
inspire safety professionals to address health and wellbeing in similar
ways to safety. It may also help health and wellbeing professionals to
put these issues higher on the agendas of the senior leaders of their
organizations. The indicators may then support a shift to a more com-
prehensive perspective and fruitful cooperation between the various
SHW professionals. As the management of psychosocial risks and
wellbeing is generally least developed, the indicators imply a great
potential for improvement in these areas. Whether this potential will be
used or not, will, of course, mainly depend on organizations in various
sectors.
Another one of the key criteria for the development of the indicators
was their applicability across different types of organizations, including
SMEs. This was a challenging aim in the development process, as was
8
highlighted through the feedback received during the pilot. It is widely
acknowledged that SMEs often lack structure, a strategic outlook and
resources (Champoux
& Brun, 2003).
Several changes were made to the
indicators to make them more applicable to SMEs, including additions
of new indicators and introduction of new measurement options. The
measurement options allow for a qualitative evaluation that may be
more applicable to smaller organizations. However, it is acknowledged
that some of the indicators may still be ambitious for smaller organi-
zations to use. Furthermore, it is acknowledged that not all organiza-
tions will use all indicators. They may choose to begin with those that
make sense in their context, level of knowledge, processes and im-
mediate priority issues. However, they can be useful in providing gui-
dance in terms of good practices across organizational contexts and
help organizations develop a more long-term strategic perspective on
the basis of prevention in all areas of SHW.
Benchmarking was another one of the key criteria in the develop-
ment process. That fact that the indicators were to be useful for
BEU, Alm.del - 2020-21 - Bilag 26: Orientering om rapport og artikel fra NFA om proaktive arbejdsmiljømål til arbejdspladsernes forebyggelsesarbejde, fra beskæftigelsesministeren
G. Zwetsloot, et al.
Safety Science 130 (2020) 104890
benchmarking implied that in the process of selection of proactive
leading indicators, it was important to choose indicators that could be
measured quantitatively. Sometimes quantity can be realized at the
expense of quality. To compensate for the fact that qualitative factors
are neglected in the indicators, each factsheet contains five good
practices. However, it is important to note that all three measurement
options would need to be tested in practice in order to establish how
feasible and useful they are, and the level of resources they require, as
e.g. option three will require more resources and would be more sui-
table for larger organizations. This would allow further development to
enable benchmarking. Organizational performance could then be
compared with high performers and targets could be set in the short and
longer term.
The development of this set of proactive leading indicators was
triggered by a request from industries that had associated themselves
with the ISSA Vision Zero campaign. The need for a harmonized set of
leading indicators is illustrated by both the high numbers of indicators
identified in this study, and a study by
Searcy et al. (2016),
who
identified 892 distinct work environment indicators in 100 Canadian
CSR reports. Indeed, there is a need for a set of (proactive) leading
indicators that is broadly accepted, in order to allow benchmarking
within and between industries, countries and continents. Now that this
set of 14 indicators is available, industries can start using it, and ISSA
and its affiliated organizations will promote the use in the more than 80
countries involved in the global Vision Zero strategy.
Furthermore, the proactive leading indicators are not only useful to
organizations that have committed themselves to VZ. Leading in-
dicators, including the 14 indicators developed in this project, overlap
with those covered by instruments which measure safety climate and
OSH management systems, which in turn overlap with process safety
indicators and management system performance (ANSI/API,
2010).
The
indicators support a continual improvement process and can be used by
any organization that genuinely aims to continually improve SHW.
While VZ has been criticized for focusing too much on outcomes rather
than processes, and that counter-productive and costly effects are likely
to stem from the inaccurate ways of interpreting and implementing VZ
(e.g.
Dekker, 2014),
these proactive set of leading indicators may
clearly help to overcome the scepticism and poor practices, as the
nature of the indicators will support organizations to be innovative, and
by making leaders or organizational units accountable for objectives
related to the indicators.
This study implemented good practice through the use of a multi-
stage mixed methods approach based on KTE principles. However, it is
important to recognize some shortcomings. First, the study would have
benefited from a large sample size in the pilot study, with more re-
presentation from SMEs and companies in a more diverse range of in-
dustrial sectors. Furthermore, a drop-out was observed in the pilot
survey, as more feedback was provided for the initial four indicators
than the last three, which is a common issue with online surveys. The
pilot focused on the evaluation of seven indicators (one for each golden
rule) where measuring quantitatively was the only measurement op-
tion. This implies a limitation, as in every situation qualitative factors
are also important. Finally, the ISSA VZ golden rules for prevention
were used as a guiding framework for the indicator development. This
implies a possible conceptual limitation, however, the extensive review
and KTE processes ensured that the indicators were evidence-based and
had practical value.
5. Conclusion
A set of proactive leading indicators for safety, health and wellbeing
at work was developed to support ISSA’s Vision Zero strategy.
Principles of knowledge transfer and exchange were integrated in a
mixed method approach in four stages. The result is a set of 14
proactive leading indicators, two for each of ISSA’s Golden Rules for VZ,
with associated factsheets and a Guide which will be available on ISSA’s
9
VZ website (http://visionzero.global/indicators). The proactive leading
indicators are not only intended to better direct and control SHW re-
levant processes, but also to support the development of a prevention
culture. Indeed, even the qualitative use of the indicators can support
agenda-setting for proactive activities. The ‘communicative power’ of
the indicators is important for VZ and a prevention culture (Zwetsloot,
2014; Zwetsloot et al., 2017a).
Due to the fact that we included only
indicators that do not require additional tools, they are relatively easy
to communicate and understand. Several of the proactive leading in-
dicators also could have a symbolic message which may have a positive
impact on the development and credibility of a prevention culture (e.g.
when leaders and workers are trained before they start their job).
It is important to stress that this is only the beginning of the process
and a first step towards a harmonized/standardized set of SHW in-
dicators. It is vital that the indicators are used in practice and are tested
in organizations across sectors, sizes and countries. This will allow the
development of evaluation case studies to ascertain the impact of the
use of indicators in practice, their usability and potential further de-
velopmental needs both within and outside the VZ framework. If the
indicators are implemented sufficiently and benchmark options are
developed, this may lead to an informal standard on proactive leading
indicators, which can be refined and improved after future research.
