Tier T3 · Lifecycle
Lifecycle — how the book moves through its phases.
Opened and closed volumes, close velocity, how long still-open work sits in each phase, and reopen rates — the shape of the book over time, computed from key dates.
How to read this page
What this measures
Work items opened per year, median age of still-open items by phase, close velocity, and reopen rate — from the key-date history.
How to read it
The trend shows intake over time; the phase chart shows where open work sits longest. Phases past the stuck threshold are highlighted.
Why it matters
Long-lived open phases and rising reopen rates are where matters silently stall — the queues a practice lead should look at first.
Watch for
The stuck threshold is an attention heuristic, not a status determination. A long median age can be legitimate for slow-burning work.
