The Agile team doctor -- don't be intimidated! It's not a new role. It can be executed by any team member in order to assess the health of the team.
I'm not talking about comparing teams but stressing that self-evaluation can be done by teams to perform better. Coaches, ScrumMasters, team members . . . anyone can perform this quick check. The primary motive is to succeed as a team in Agile. These aren't sophisticated techniques -- just common sense.
Nor am I talking about the solutions! Because those should come from you, as you are the person who knows the team and the required dynamics.
So here are some areas that can aid in knowing the health of the team:
Check the team pulse, i.e., its "Comfort Factor." This gives an idea of how well the individuals are gelling within the team.
Check the "Cheer Factor," which gives the happiness quotient of the team at work.
Check the "Complacency Factor," which will give an idea of whether the team is pulling the work proactively or is just happy with the things on their plate.
Check the "Collaboration Factor," which gives an idea of how good the team is when dealing with internal/external entities.
Check the "Commitment Factor," which gives an idea about the team's commitment and delivering on that commitment.
The 5Cs (Comfort, Cheer, Complacency, Collaboration, Commitment) can act as the decision factors to tell whether the team is "Terrific" or "Terrible"! So do the 5C Check and immediately act on anything that comes up short.
