How to Use - and NOT Abuse - Software Engineering Metrics
Quantity over quality. As you stated, we should stop trying to measure and track everything and rather first spend time deciding what metrics would help us improve our work process and then only measure those.
Makes everything much more easy and efficient.
Metrics should be a discussion starter. Indeed. Discussions are what provide value to metrics. Without any discussions, it would be vague estimates that hardly render any value.
On the other hand, if you discuss, you get to the roots and have the opportunity to fix things right and discuss better ideas.
As important as it is to know what needs to be tracked to analyze the performance of a software engineering team, it is also important to know how the produced data can be used to favor the productivity and effectiveness of the team.
