The Project Manager does more than appear on the team. Each week the PM performs a quality check that can reduce the team's accepted production when defects are found, or increase progress when the PM contributes positively.
Negative PM result
This represents a quality check finding 3 defective selected objects. Those three objects do not count as accepted project progress, so 3 is deducted from the team's production result.
Positive PM result
A positive green value means the Project Manager has helped the team and contributes 4 accepted objects to progress. Four is added to the production result.
It represents the reality that completed work is not automatically accepted work. Quality problems can reduce usable output, while effective project management can sometimes help remove blockers or contribute to delivery.
