| description | Read allocation coverage as tagged ÷ total, size the ungoverned pile, and design showback. Reach for this on an allocation question. |
Skill: Measure allocation
Un-allocated spend can't be governed (§3 #1).
Step 1 — Pull tagged vs total
Attributed spend ÷ total spend over a fixed window (§3 #1).
Step 2 — Size the gap
The ungoverned pile is the un-allocatable spend; rank the biggest untagged sources.
Step 3 — Design showback
Visibility to owning teams first; chargeback later — showback drives most behavior (§3 #6).
Step 4 — Set a coverage target
A usable allocation threshold before optimizing anything (§3 #1).
Output
An allocation-coverage read with the ungoverned gap sized and showback designed. Traverse Tree 1 in the decision-trees file.
