Avg Member WIP Age is the average age of a member's currently in-progress items — measured from when each item first entered an active state to right now. It's the best leading indicator of stuck work.
What it measures
For each item that's currently active for this member, how long has it been in progress? Average those numbers.
How Leanmote calculates it
wip_age(i) = now - in_progress_at(i) avg_member_wip_age = avg(wip_age(i)) for items where assignee = member and status in active_states
Computed live — the value moves every day items stay open.
Per-team rollup is the simple average of member values, weighted by their WIP count.
How to interpret it
Rising WIP Age while Throughput is flat means items are aging without finishing — the team is starting more than it can complete.
One member with sharply higher WIP Age usually has a single stuck item dragging the average. Find it.
WIP Age much larger than Avg Member Cycle Time tells you items are taking unusually long compared to past completions — re-plan or split.
What to do about it
Run a "stuck items" sweep weekly: filter for the highest-age items and ask what's blocking each.
Cap WIP per person so age can't compound.
Encourage finishing before starting new work — pull, don't push.
