Path Group War Room

Running the last weeks of closure as a daily routine: triage, ownership, escalation, and the long tail of the hardest endpoints.

  • 4topics
  • 4lessons

Near the end of a project, hundreds of violations and a dozen owners need coordination. A short daily routine keeps it manageable: classify endpoints by what changed, give every endpoint an owner, escalate on arithmetic rather than mood, and treat the long tail as a different problem from the bulk. This topic gives the routine with runnable examples.

Lesson

After it you can...

Daily Triage

Sort endpoints into new, regressed, stuck, improving and dropped.

Owner Assignment

Assign every endpoint to an owner and find the orphans.

Escalation and Signoff Risk

Escalate from backlog and fix rate.

Closing the Long Tail

Separate the bulk of TNS from the last violations.

The prioritisation ideas are in Path Group Prioritization; this topic adds the process around them.

Check yourself Why does every endpoint need an owner?

An endpoint nobody owns is a violation nobody is fixing: it will still be open at the end, unless the process catches it.

Interview

Describe how you would run the last two weeks of closure, in three or four sentences.
