Identify the expected next condition and the evidence needed before replacing a control.
Review source hierarchy
Know when to use the applicable adopted code, equipment instructions and project documents.

Plan the day
Confirm official arrangements and practise the permitted tools and references.
Read the actual instructions and plan time for calculations and marked review items.
Check units, given assumptions, sequence order and whether a choice addresses the cause rather than bypassing protection.
