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.
Function Modelling Explained: From Mission to Capabilities via Goals, Processes and Services
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.
