leadtime

leadtime - calculate PR lead time statistics on GitHub

leedtime is a command that outputs statistics about the time it takes for a GitHub Pull Request to be merged. The leadtime command was developed under the influence of the following books.

• Eng: Accelerate: The Science of Lean Software and DevOps: Building and Scaling High Performing Technology Organizations
• JP: LeanとDevOpsの科学［Accelerate］

The motivation for developing the leadtime command is to measure lead time for changes. I used unit test coverage as a measure of software quality. However, as the number of unit tests increased but the code was not rewritten, I questioned whether the quality was improving.

Therefore, I considered measuring lead time, one of the indicators presented in the above book.
