The rate at which the system generates money through sales.
This is often the hardest step for managers to accept. All non-bottleneck resources should be aligned to support the constraint. This means accepting idle time on other machines—because pushing more work into the system than the constraint can handle only creates excess work-in-progress and extended lead times. By definition, non-bottleneck resources should not be used to full capacity.

Eliyahu Goldratt's 1984 bestseller, The Goal: A Process of Ongoing Improvement , is unique for being a business novel . It uses a fictional narrative to teach the Theory of Constraints (TOC)
Through Socratic questioning, Jonah guides Alex to discover the flaws in traditional cost accounting and operational metrics. The rate at which the system generates money through sales
To achieve this, Goldratt introduces three operational metrics that replace traditional cost accounting definitions:
Constraints can take several forms in a system. A might be a specific machine or department that cannot keep up with demand—the bottleneck in the production line. A market constraint exists when a company could sell more products if only it could produce more; here, the market itself is the limiting factor. Policy constraints are particularly dangerous because they're often invisible—management decisions or ingrained company cultures that limit system performance. In The Goal , Goldratt famously shows how a resource constraint was left idle during lunch breaks and shift changes, losing up to five hours of production per day. This policy, not any physical limitation, was the real constraint. Finally, there are dummy constraints , which are easy to break once identified—like the setup crew that could easily be dedicated to the bottleneck machine for minimal cost. This means accepting idle time on other machines—because
One of the most famous analogies in business literature occurs when Alex Rogo volunteers to lead his son’s Boy Scout hiking troop. He notices the line of hikers continuously stretching out, creating massive gaps.
This production planning and control system synchronizes manufacturing based on the bottleneck: The bottleneck sets the pace for the entire plant.
The ultimate goal of any manufacturing business is simple:
