There are many different definitions for what constitutes an incident or an accident, however the focus is always on
unintended and often unforeseen events that cause unintended consequences. This article is focused on the process of
learning from incidents and accidents. The focus is on making sure that the lessons learned from incident investigations
are implemented and lead to an actual improvement in safety. For this article we will use the terms incident for accidents,
near misses and other unwanted events.
Why learn from incidents
Many organisations have problems in reducing the number of incidents and this can be partly attributed to the failure to
learn the lessons from incidents that had occurred[1][2][3]. Incident prevention is strongly based on learning from
previous incidents. When incidents occur they raise awareness and understanding of things that went wrong, and perhaps
can go wrong again. The challenge is to learn as much as possible about the causes of accidents and near misses that
have already happened in order to prevent reoccurrence[4]. When experiences of previous incidents are translated into
preventive measures, an organization can prevent incidents in the future and the need for repressive actions at that time.
Learning is acquiring new or modifying existing knowledge, behaviours, skills, values, or preferences and may involve
synthesizing different types of information (Argyris, 1992). A learning organisation actively creates, captures, transfers,
and mobilises knowledge to enable it to adapt to a changing environment[5]. When learning from incidents the
organization uses the information from incidents to change, to actively improve and to prevent future incidents.
It is also useful to learn from incidents of others. Knowledge from these incidents allows for comparison with the own
situation and systems and enables you to generate creative solutions and take time to prioritize the measures.
Immediately after an incident occurs in an organisation, the situation has changed. There is limited time to consider
different solutions, sometimes causing the selection of suboptimal measures[4].
Steps in learning from incidents
The step that has been most frequently described and analysed in literature on learning from incidents is incident
analysis[6]. The investigation and analysis of an incident can be made in several ways.
Learning from incidents and accidents: OSHwiki
However the need for follow-up steps has been described as well. Schein (1996) for example emphasises the need for
dissemination of lessons learnt within an organisation[7]. Lindberg (2010) developed a CHAIN model in which lessons
are disseminated and used for preventive actions. Drupsteen et al. (2011) developed an analytical framework to analyse
where problems in learning from incidents arise[8]. This framework enables analysis of the learning from incidents
process and consists of several steps, divided into four blocks or phases: incident investigation and analysis, planning of
interventions, intervening and evaluation. This evaluation includes the implementation of actions, the effectiveness of the
action and also an evaluation of the quality of the learning process itself. This is a cyclical process that should be fully
completed to establish learning. If an intervention is not effective, the actions or the analysis should be re-evaluated and
adjusted. This can to some extent be compared to the evaluation of implementations that are based on recommendations
from an audit or a risk assessment. In this way, incidents can be regarded as interesting warning signals and as
opportunities to learn. The outcomes of this process are iterative: a plan of action is made, the actions are performed and
actions are evaluated. Based on this evaluation new lessons are formulated. This sequence is also known as the plan-docheck-act cycle by Deming[9]. Experiential learning models that are similar to the Deming cycle can also be used to
describe and analyse collective or organisational learning processes[5][10][11].
It is important to recognise that there can be a number of barriers to effective learning from incidents and accidents.
These can include 'fear, blame and anxieties about reputational loss and legal proceedings'[12] and can be enhanced (or
alleviated) by the culture within an organisation.
Learning theories
To learn from incidents, some organisational factors are important. These aspects are related to the structure or to safety
management, such as incident registrations and action plans, or to the organisational safety culture, such as transparency,
blame free culture, and feedback on unsafe behaviour.
The actual performance – but also the learning – of organisations is determined by the practical activities in
organisations, referred to by Argyris as theory-in-use. Managers all too often only learn through ‘talking and thinking’
without actually changing their behaviour. This is what Argyris & Schön (1978) call espoused theory. Also auditors of
safety management systems that focus too much on the documentation of procedures, and do not carefully investigate the
actual practice, are less effective because they address mainly the espoused theories of the organisation.
In contrast, operators are often sent to training sessions where they learn to do something but the attention paid to this
improved understanding and knowledge is often too minimal [10][11]. A recent study illustrates the differences in
espoused theory and theory-in-use when learning from incidents, according to safety professionals. These results indicate
that arranging incident analysis and follow up steps are not sufficient for learning[13].
Levels of learning
An important aspect of learning from incidents is that the processes can be thought to address different ‘levels’ of
learning[14](Argyris & Schön, 1978)[5]. Different theorists have presented taxonomy’s for qualitatively different ways to
learn either as an individual or organisation. Piaget (1969), who focused on learning in schools, distinguished three
distinct levels of learning[14]:
being able to reproduce certain knowledge;
being able to apply the knowledge in a similar setting as it was first offered;
being able to apply the knowledge adequately in other (new) settings.
A well-known distinction in organisational learning research is between so called ‘single loop learning’ and ‘double loop
learning’ (Argyris et al., 1979). Argyris’ concepts are related to Gregory Bateson’s concepts of first and second order
learning[15]. If an organisation exhibits single loop learning, only the specific situation or processes are improved.
However when an organisation exhibits double loop learning, improvements are not limited to the specific situation but
the values of the theory-in-use is evaluated and changed as well (Argyris et al., 1978);[16].
When investigating an incident that was caused by a malfunctioning valve this could for example mean that:
1. a defective valve which caused an incident is replaced by a functioning valve of the same model (single loop
2. a defective valve which caused an incident is replaced by a new more appropriate type of valve (double loop

An important kind of double loop learning is the learning through which the members of an organisation may discover
and modify the learning system. This so called learning to learn process (called Deutero learning by Argyris & Schön)
enables an organisation to continuously improve. In this process systems thinking and the mental models of the key
actors – who are able to change the system – are key[5]. Senge also demonstrates that many learning processes are
actually hindered by unintended counter-balancing processes.
In our example of an incident caused by a malfunctioning valve a measure that could be seen as a result of ‘learning to
learn’ could be:
1. In response to an incident caused by defective valve regular equipment audits are improved. In addition systems
are put in place to regularly re-evaluate both the overall quality of valves and the quality of the valve monitoring
Another theoretical model describing ‘levels of learning’ is presented in the later works of Argyris (1990)[17]. He
distinguishes two styles of learning, and called them respectively Model I and Model II learning. His empirical works
clearly show that Model II learning, which is characterised by the open sharing and discussing of reliable information,
decision-making based on free informed choice, and internal commitment on decisions made, complemented with
monitoring the implementation, is much more effective for the achievement of meaningful changes and innovations than
the preferred learning style of most organisations, i.e. Model I learning. In Model I learning ‘inferences about another
person’s behaviour without checking whether they are valid’ are made and views are advocated ‘abstractly without
explaining or illustrating one’s reasoning’.
The following overall conclusions can be made:
Despite efforts to investigate and learn from incidents many companies still have difficulty to sustainably learn the
lessons from previous incidents. More effective learning from incidents or accidents could help prevent accidents
in the future.
Theorists have developed models that describe the steps that a company needs to take in order to learn from
incidents. These models could help further improve safety management.
There are many organisational learning theories that can help scientists and practitioners understand learning from
incidents in their organisation. Useful distinctions are between: espoused theory and theory-in-use; single loop and
double loop learning; learning to learn or deutero learning.
