PR throughput per contributor represents the number of PRs opened and closed by individual contributor of the team.
Note: This metric only takes active contributors into account and does not count people who have not made a code contribution in the selected time period.
This metric helps to understand the contribution by each member.
For eg: If the contribution of any member is low, it may be an indication that the person may be facing some bottlenecks like difficulty getting reviews etc.
It may also be an indication that the person is working on very large PRs or a combination of both.
