When refactoring messy business logic, 'cleaner' code often masks dangerous behavioral changes. Discover why your unit tests might show 86% coverage while still missing critical logic errors that break your production environment. We explore the transition to a specification pattern and the hidden traps of assuming you've truly understood legacy requirements.
Most software projects die under the weight of their own complexity. We build features 'just in case' and create deep inheritance trees for problems that could be solved with a simple function. This hidden technical debt eventually makes the code impossible to maintain, leading to bugs that hide in plain sight and development cycles that grind to a halt. Discover how to reclaim your productivity by applying ten essential rules of simplicity, including the 10% refactoring habit that keeps projects lean.
