Get introduced to the importance of metrics for gauging your team's performance.

“When you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind.” —Lord Kelvin

Metrics are a commonly-used tool to help gauge the performance of a team, and are frequently the tool of choice for engineering managers who are first looking for clear, objective(-ish) ways to judge the performance of an individual or a team. However, as with most tools in software development, over-reliance on metrics can have the exact opposite effect than desired, and in many cases can lead to the very undesired behavior they were trying to protect against.
