I subscribe to Mike Cohn’s newsletter and I received a post on January 20th, 2022 entitled—
7 Reasons Teams Underestimate Work.
It was quite short but sweet and valuable. I’m sharing his list of seven factors below.
Overconfidence
Lack of clarity about the feature
Estimating a best-case scenario
Multi-tasking is not considered
They aren’t including time to iterate
Not all work is included
Assuming they’ll be more productive than is realistic
And it inspired me to think of other reasons, not directly related to the team, that might cause the team to underestimate.
