Strategic Transformation in Procurement with the 15M Architecture

A practical guide to the 15M Architecture, a proven framework for turning procurement into a genuine strategic partner to the business. Written by Prof. Dr. Gerhard Heß and enhanced with real-world insights from Sourcing Champions, this white paper breaks down how to structure, mature, and future-proof your procurement function, step by step.

• A complete strategic blueprint — see how the 15 modules connect business strategy, category management, supplier relationships, digital processes, and procurement management system into one coherent system
• A way to diagnose your procurement maturity — understand the 5-stage maturity model (from purely operational to world-class sourcing champion) and where your organization likely sits today
• A framework that grows with you — learn the modular, evolutionary approach that lets you start anywhere and build capability step by step, without a disruptive overhaul
• Built-in risk and sustainability integration — see a real example (CO₂ reduction) of how a single target cascades through every layer of procurement decision-making
• A practical starting point — get the “how to start” guidance distinguishing the ideal sequence from the pragmatic, real-world path most companies actually take
