Productive throughput and efficiency

What

This section gives critical metrics on code quality, and the overall productivity of the work being committed.

1. Code churn: Code that is deleted/rewritten within 21 days of merging is called code churn or rework
2. Productive Throughput and Efficiency: Code that is not churned, that is, code that does not get rewritten/deleted within than 21 days.
3. Efficiency: Percentage of Code that does not get churned.

Why

1. Identify problematic areas of code
2. Identify problematic repositories
3. Identify lack of expertise or a need to upskill your engineers
4. Identify potential quality issues and probability of bugs in future edits
