Presets
Little's Law is deceptively simple and astonishingly general: the average work-in-progress equals throughput times lead time. It holds for any stable queue — a factory, a hospital, a software backlog, a checkout line — regardless of the details. It means the only ways to cut lead time are to raise throughput or reduce work-in-progress, the core insight of lean and agile.
