Share Pie: The DDD Treasure Hidden in Plain Sight
summary
Chapter 8 of the DDD book drives a concrete claim: after a long New York winter of refactoring on syndicated-loans software the team discovers a share pie model that unifies loan and investment shares, simplifying rules and making new features easier. The team uses example mapping (and mentions event storming) to work through numeric scenarios, asks for weeks of refactor time from the project manager, implements the model, and sees accelerating development versus the baseline complexity (Adam Tornhill’s research notes up to 42% time lost to technical debt).
