Lesson 215 - Fitness Function Driven Architecture

Fitness Function-Driven Architecture (FFDA) is a technique where architects write fitness functions—measurable objective integrity assessments of some sort of structural or operational characteristic of the architecture—to achieve an eventual goal, much in the same way developers use Test-Driven Development (TDD) to first write a failed test, then develop code to make the test pass. In this lesson I demonstrate how FFDA works and how you can apply it using real-world examples to achieve a desired architecture goal.
