Clarify what has happened and the nature of the problem or concern
Discuss with the NCAS or CDU what the way forward should be
Consider whether restriction of practice or exclusion is required
If a formal approach under the conduct or capability procedures is required, appoint an investigator
If the case can be progressed by mutual agreement consider whether an NCAS or CDU assessment would help clarify the underlying factors that led to the concerns and assist with identifying the solution.
