What goes in the matrix
Use one row per competency and state the level the role requires. In each person’s column, note the observed level, the source of the observation, and the date. Give missing evidence its own status.
An example row
For negotiation, the target might be to agree a compromise between two functions without escalation. The evidence could be a review of two recent negotiations. If the person has yet to face that situation, plan an opportunity to observe it.
How to act on the matrix
Choose one competency the team needs to strengthen. Identify a task for practising it, decide who will provide feedback, and set a date to revisit the rating.
