As a start we recommend using the 1 to 4 rating score for each task. Briefly;
1 means the team member has less than 75% training in the task
2 means that the team member has >75% training but has not proven their ability to perform the task without some guidance.
3 means that the team member can perform the task with no guidance needed
We recommend that they should ‘pass’ an objective internal test to prove operational capability.
4 means that the team member has significant experience and can be involved in raining others.
Level 3 is the level that is regarded as ‘capable’
