Kent Beck's 'Tidy First?': Because calling refactoring 'cute fuzzy tidying' might finally trick your PM into approving code cleanup before the next pivot

Kent Beck, a renowned figure in the software development field, has written a new book titled "Tidy First? A Personal Exercise in Empirical Software Design", which focuses on code quality, a topic not often prioritized by developers. The book, which comes after similar works such as "Refactoring" by Fowler in 1999 and "Clean Code" by Robert Martin in 2008, explores the concept of "tidying" as a small, incremental refactoring that improves code quality. Beck defines tidying as "cute, fuzzy, little refactorings" that are essential for maintaining good code structure. The book discusses the importance of coupling and cohesion in software design, referencing the work of Ed Yourdon and Larry Constantine, and introduces the concept of "Constantine's Equivalence", which states that the cost of software is equivalent to the cost of change. The book's significance lies in its emphasis on the economic and temporal aspects of code quality, providing developers with a framework to make informed decisions about when to prioritize tidying and decoupling in their development process.
