name	rank-multi-unit
description	Rank comparable units against each other, normalized for format and daypart, to find where the margin actually is. Reach for this on a portfolio review.

Skill: Rank multi-unit variance

The chain average hides the money; the best-vs-worst spread reveals it.

Step 1 — Normalize the comparison

Group units by format/daypart so the comparison is apples-to-apples (§3 #7).

Step 2 — Rank on prime cost and margin

Order units on prime cost and four-wall margin within each group.

Step 3 — Isolate the spread

Quantify best-vs-worst and attribute it to operations, not format.

Step 4 — Prescribe to the laggards

Map the top quartile's practices to the bottom.

Output

A normalized store ranking, the best-vs-worst spread, and a laggard improvement plan.
