Michael Feathers (R7K Research & Conveyance) is a luminary, expert in software and organization design, and author of Working Effectively with Legacy Code. Over the past 20 years, he has spoken at conferences around the world, and some even call him the “godfather of legacy code.” In this episode, we discuss software best practices, Conway’s Law – or as Michael sometimes calls it, The Fundamental Theorem of Software Engineering –, the impact of code that could be deleted, and feature selection.
