My issue is this: I already have individual performance evaluations (e.g., Team member 1 = C, Team member 2 = B, Team member 3 = A... and the grades are T, A, B, C, D) and now I have to make a tool in which the team will be able to see what its total grade is, enabling the team to compare with other teams. So, do I calculate the average from individual grades, or is there a formula for that, or is there a form like this: To be at a certain competence level, the team needs to have at least 30% of team members at that level.
I will be very grateful for any kind of information.
Best regards,
Vedrana
