A Diagnostic for Leaders Accountable for an ERP

The ERP
Operating-Model Score.

Fifteen questions. Five dimensions. One number that tells you whether you run an operating model — or just bought a system.

Most ERP maturity models let you lie to yourself. Generic Likert scales, vague language, comforting averages. This one is built to do the opposite.

Every question has anchored answers describing a concrete picture of how your core system actually runs. Pick the one that's true today — not the one you'd like to be true. The diagnostic finds your floor, not your mean. The floor is where the next decade of risk is hiding.

15 questions across 5 dimensions 5 anchored answers per question Result reveals an archetype + a fix-first priority
