Day 27 / 100 · Kanban & flow · Blockers and ageing work

Old work is a warning.

Items that sit still get more expensive every day. Make blockers and age impossible to ignore.

Mark blockers

Habit 01

A visible tag with the reason and the date it started.

LOOKS LIKE

“Blocked: vendor test env, 3 days.”

Show age

Habit 02

Days in progress on every card, updated daily.

LOOKS LIKE

Old cards stand out.

Swarm the oldest

Habit 03

Walk the board from the right. Oldest items get help first.

LOOKS LIKE

Daily Scrum, right to left.

Learn from blockers

Habit 04

Group blocker reasons monthly and fix the common causes.

LOOKS LIKE

Fix the system, not the card.

Old work is a warning. Act before it's late.
