Pete’s workers are able to speed themselves up to compensate for their early delays, demonstrating that an independent event can easily maintain its statistical average. However, the fact that the robot cannot operate at full capacity because of Pete’s workers’ early delays demonstrates that in a chain of dependent events, every delay is passed down the entire chain; although Pete’s workers can maintain their own average, their initial delay throws off the robot’s pace. This is the fundamental problem that Goldratt’s Theory of Constraints seeks to solve.
