How do small improvements compound over time?
Each small improvement becomes the new base that the next one builds on, so the gains multiply rather than simply add up. The book's example: improving a process by just 1% each week leaves you almost 70% better after a year, not 52% better, because every week you are improving an already improved process. Consistency over time does the heavy work.
The book compares improvement to compound interest. A small sum, added to consistently, grows into far more than the sum of the deposits, because growth applies to a growing base. A process works the same way.
Improve a process by 1% this week and it barely registers. Next week, though, you are not improving the original process. You are improving the slightly better one, and the week after that, a better one again. That is why the book says a year of 1% weekly improvements does not produce 52% improvement, and why it describes the difference after five years as astronomical.
The practical consequence is that small is not a compromise. It is the mechanism. A change small enough to make this week, and keep making, beats a large change that is planned repeatedly and never started.
To make the compounding visible, the book suggests a Small Wins Log: a simple document or channel where the team records each day's small improvement or solved problem, then reads the log together at the end of the week and celebrates the progress.
“After a year, you’re not 52% better (1% times 52 weeks). You’re actually almost 70% better.”
