This text integrates Lean concepts, Six Sigma, and the Theory of Constraints into a combined business strategy aptly named the Ultimate Improvement Cycle (UIC). Unlike other systems, the UIC is all about economizing resources by focusing improvement efforts on those key leverage points that will prove most optimal, rather than diluting one's efforts with an expensive across-the board-approach to improvement. The UIC is derived from Bob Sproull's years of executive experience with the Toyota Production System and consulting work with several high profile companies. He shows you how to take advantage of the cyclical nature of improvement to implement change that is perpetually effective, and his approach does not require more resources than you have on hand.
