The health care industry has studied measuring pain and have very good data on their ability to measure and administer pain drugs upon a subjective self report. Maybe we could do the same in knowledge worker teams and work groups.
|Team Happiness Net Promoter Score sheet|
"How likely is it that you would recommend our team to a trusted friend that is looking for a job?"
To calculate the NPS - the continuum is divided into 3 groups; the detractors (1 - 6), the passive (7 & 8), the promoters (9 & 10). The passive are ignored - they do not promote your objective. The NET promoter score is the percentage of people promoting your objective minus the percentage of people detracting from your objective.
NPS = Promoter % - Detractor % (valid range +100% to -100%)
How does this objective of promoting your team as a recommendation for a friend seeking a job a proxy for team happiness? I've not met many good people that would shaft a friend by recommending an unhappy team - have you?
Note: with small populations (like a scrum team) there is high variability based upon a few people's scoring, another companion metric would be the percentage of people participating in the survey. Did the whole team play - or do you have a core group that is the in-group?
