Using evidence and diverse perspectives to reach sound conclusions, and being able to justify decisions under scrutiny.
This behaviour is scored on your reasoning, not just your outcome. Assessors want to see that you gathered relevant evidence, considered more than one option, and can explain why you chose what you chose — including what you'd have done differently with more time or information.
Describe the decision that had to be made and why it wasn't obvious — genuine trade-offs, incomplete information, or time pressure.
State that the decision (or the recommendation) was yours to make, and what was at stake if you got it wrong.
Walk through what you actually did: what you checked, who you consulted, what options you weighed, and why you ruled the others out.
Give the outcome, and — this is what separates strong answers — a brief, honest note on what you'd check differently next time.
