What Makes a Good Incident Investigator?

Many organisations invest heavily in investigation templates, software systems and reporting formats. While these tools can support consistency, they do not automatically create strong investigations. The quality of an investigation is still largely determined by the investigator's capabilities and mindset.

Curiosity Before Conclusions

Good investigators are not simply people who know the methodology. They are people who remain curious, analytical and open-minded throughout the investigation process.

One of the biggest risks in incident investigation is premature certainty. Once investigators become convinced, they already understand what happened, and the quality of questioning often declines. Alternative explanations are overlooked; assumptions remain unchallenged, and important contextual information may never surface.

Strong investigators remain cautious about early conclusions. Rather than looking for quick answers, they actively seek to understand the broader context surrounding the event. This includes exploring aspects such as:

• Multiple perspectives

• Operational realities

• Organisational influences

• Conflicting information

• Context surrounding decisions and actions

Interviewing Skills Create Better Investigations

Interviewing capability is another essential skill. People involved in incidents may feel vulnerable, defensive or afraid of consequences. The investigator must create enough psychological safety for open conversations to occur. This requires empathy, neutrality and strong listening skills.

Effective interviewing also requires the ability to explore more sensitive topics. Discussions about procedural deviations, production pressures, conflicting priorities or previous concerns can sometimes feel uncomfortable for both the investigator and the interviewee.

Less experienced investigators may occasionally avoid these areas because they fear creating tension or making the interviewee feel accused. Yet these conversations often contain some of the most valuable insights. The challenge is not to avoid difficult topics, but to explore them with curiosity, neutrality and respect.

Understanding Operational Reality

The best investigators also possess sufficient operational understanding to ask meaningful questions. Without understanding the work environment, investigators may overlook critical operational realities or unintentionally focus on paperwork rather than practice.

Avoiding Hindsight Bias

Another important capability is the ability to avoid hindsight bias.

After an incident, the outcome often appears obvious. However, investigators must remember that the people involved did not have access to the same information or the same level of certainty beforehand. Good investigators seek to understand how the situation appeared at the time rather than judging decisions purely based on the outcome.

Looking Beyond the First Explanation

Consider a situation in which a technician bypassed part of a maintenance procedure before restarting the equipment. During the initial interviews, the explanation appeared straightforward: the work had been carried out under significant time pressure, and the technician felt pressured to complete the task quickly.

At first glance, the investigation seemed almost complete. Time pressure appeared to provide a sufficient explanation.

However, further conversations revealed a more complex picture. The technician had been interrupted several times during the task, was supporting multiple jobs simultaneously and was relying on a procedure that was difficult to use in practice. Investigators also discovered that similar shortcuts had gradually become the norm within the team as operational demands increased.

What initially appeared to be a simple case of time pressure turned out to involve a combination of workplace conditions, procedural weaknesses and local practices. Without careful interviewing and a willingness to look beyond the first explanation, much of this context would likely have remained hidden.

What makes a good incident investigator?

Contrary to popular belief, it is rarely the methodology, template or software alone. More often, it lies in the investigator's ability to remain curious, ask meaningful questions, understand operational realities and create the conditions for honest conversations. That's what makes a good incident investigator.

Developing these capabilities takes time, practice and reflection. They are often what transforms an investigation from a compliance exercise into a genuine opportunity for organisational learning.

For organisations that are serious about learning from incidents, investing in investigator capability is just as important as investing in investigation methodology.
