Maths, not art

The transformation integrity series

Ten articles on why migration assessments measure the wrong thing — and what to measure instead. The mathematics is universal. The examples are from SAP. Start anywhere.

Start here: If you read one article, read The 98% Problem. If you want the mathematics, read Bijective Proof. If you want to understand the engine, read Five AI Personas.
