The Situation

You're part of the planning team for a hydrographic reef survey, one leg of a multi-stop deployment. The schedule is already tight, and today's survey window is shorter than planned after a delay earlier in the week. The pre-survey risk assessment is due to be completed before operations begin.

The Lesson

Time pressure doesn't announce itself as a hazard — it changes what gets double-checked, quietly, unless someone deliberately protects the checks that matter most.

Human Element

None of the 12 factors the Inquiry found were individually dramatic. Haste, a gap in supervision, a procedure not quite followed — each one explicable on its own. The scenario tests whether schedule pressure changes what gets double-checked, before any of that pressure becomes visible as a crisis.

Try the First Decision

The survey window is shorter than planned. Completing the risk assessment and hazard review properly will eat further into that window. What do you do?

A. Take the time needed to complete the risk assessment properly, even if it delays the survey further

B. Compress the risk assessment to stay inside the remaining schedule
