“With TDD, you create an automated test first, and only then write the minimal amount of code that you can get away with to satisfy that test. Every time someone finds a new bug, it gets added to the fully automated test suite.

Four Days With Dr. DemingA good introduction to Dr. Deming’s philosophy of management: Four Days with Dr. Deming summarizes the four day seminars Deming used to give to business leaders. Key insight: you can’t improve your team’s performance just by picking some numeric measurement and then rewarding or punishing people to optimize it. Problem one: the variability in the measurement may be caused by a broken system that only management can change, not by individual performance. Problem two: people may optimize locally to improve that one measurement, even at the cost of hurting the performance of the company as a whole. If you’re in a rut constantly trying to figure out how to rejigger your employees’ incentive systems, this book will get you out of it.
