How do you know if a Just Culture works?

Look at the quality and distribution of reports, the time to feedback, the percentage of completed improvement measures, recurrence of similar events and the perceived fairness of research. Employees must know where the boundaries are and trust that similar cases will be treated similarly.

An increasing number of reports can initially be a good sign: previously hidden information becomes visible. Merely counting reports is therefore insufficient. Also check whether the organization learns from it, supports reporters, tackles structural causes and motivates decisions in an imitable manner.
