Software Design X-Rays

The backbone of surprise is fusing speed with secrecy.

Chapter 3Coupling in Time: A Heuristic for the Concept of Surprise

In this chapter we explore a concept called change coupling. You’ll see how change coupling helps us design better software as we uncover expensive change patterns in our code. You’ll also learn to uncover subtle relationships across clusters of files by analyzing change patterns between functions located in different files. This gives us a powerful strategy for iteratively improving our design based on feedback from how we work with the code.

As always, we’ll study the techniques on a real-world codebase to identify real problems. We’ll continue to explore ASP.NET Core MVC. We’ll also see that change ...
