Function modelling is one of the most versatile and underused techniques in enterprise architecture — a hierarchical decomposition from mission to activities that brings clarity to scope, responsibility, and design. This white paper introduces function modelling and shows how it connects to goal modelling, process analysis, service design, and capability definition, providing a unified picture of how these paradigms relate and reinforce each other. It is a practical guide for architects, analysts, and anyone trying to make sense of what an organisation does and how to design what it should do next.
Understanding and Improving Your Value Chain: A Practical Guide for Enterprise Architects
Value chain analysis is one of the most powerful starting points in enterprise architecture and business process improvement — but getting real analytical value from it requires going well beyond a Porter diagram on a whiteboard. This white paper covers the full value chain toolkit: core concepts, reference models (including SCOR and VRM), a structured approach to documenting and analysing each value chain step, and a practical framework for deciding between incremental improvement and radical redesign. It is a hands-on reference for architects and business analysts working on process improvement, operating model design, or strategic transformation.
The Difference Between Process Architecture and Process Modeling (and why you should care)
Process modelling initiatives frequently consume months of effort without producing meaningful results — often because teams dive into detailed models before anyone understands the big picture. This paper argues for a clear separation between process architecture (a rapid, high-level view of what processes exist, who they serve, and how they connect) and detailed process modelling and design, while keeping both perspectives fully integrated. Drawing on case studies from financial services organisations, it shows how this approach can cut project time dramatically and produce models that business stakeholders actually engage with.
