Root cause: reconstruct before explaining

A timeline separates verified events from interpretation.

Reconstructing decisions, conditions and changes before selecting a cause helps avoid a hindsight narrative.

What evidence would test your initial hypothesis?

Reconstructing the sequence means asking what could be observed before, during and after the event. Records, equipment condition and witness accounts may have different limitations. Making those limits explicit strengthens the analysis and reduces the tendency to interpret every detail through the outcome we now know.

During field discussion, ask how a foreseeable difficulty is handled: who can be involved and which information supports a decision? Connecting observations, ownership and feedback helps establish whether a control is workable as well as documented. The review should consider actual conditions rather than assume that the same arrangement fits every task.

For the next discussion, choose a concrete situation and ask which evidence would help explain it. Follow up the observations by making ownership of open questions visible and explaining how feedback will be provided to the people involved.
