“Just One More Thing” refers to the pattern of late-arriving pull requests.
A team submits work, but then—right before the deadline—they jump in and make additions to that work.
Due to last minute requests, poor planning or estimates, and too much work in progress.
HOW TO RECOGNIZE IT
It is characterized by a spike in PRs being submitted near the end of a sprint after the main PR was approved.
WHAT TO DO
Late-arriving PRs are a sign that work is being rushed and given less review.
Even when the work is submitted by engineers who are very familiar with the code,
the PRs should be treated as riskier than other equally sized PRs that are submitted earlier in the sprint.
