Finance is the art and science of watching the money flowing into and out of a business, then deciding how to allocate it and determining whether or … - Josh Kaufman

The philosopher kings behind what passed for management psychology were Ivan Pavlov and, later on, B. F. Skinner, who believed that if you discovered and applied just the right stimulus, people would behave however you wanted.

Every successful business (1) creates or provides something of value that (2) other people want or need (3) at a price they’re willing to pay, in a way that (4) satisfies the purchaser’s needs and expectations and (5) provides the business sufficient revenue to make it worthwhile for the owners to continue operation.

In order to find and eliminate a Constraint, Goldratt proposes the “Five Focusing Steps,” a method you can use to improve the Throughput of any System: 1. Identification: examining the system to find the limiting factor. If your automotive assembly line is constantly waiting on engines in order to proceed, engines are your Constraint. 2. Exploitation: ensuring that the resources related to the Constraint aren’t wasted. If the employees responsible for making engines are also building windshields, or stop building engines during lunchtime, exploiting the Constraint would be having the engine employees spend 100 percent of their available time and energy producing engines, and having them work in shifts so breaks can be taken without slowing down production. 3. Subordination: redesigning the entire system to support the Constraint. Let’s assume you’ve done everything you can to get the most out of the engine production system, but you’re still behind. Subordination would be rearranging the factory so everything needed to build the engine is close at hand, instead of requiring certain materials to come from the other end of the factory. Other subsystems may have to move or lose resources, but that’s not a huge deal, since they’re not the Constraint. 4. Elevation: permanently increasing the capacity of the Constraint. In the case of the factory, elevation would be buying another engine-making machine and hiring more workers to operate it. Elevation is very effective, but it’s expensive — you don’t want to spend millions on more equipment if you don’t have to. That’s why Exploitation and Subordination come first: you can often alleviate a Constraint quickly, without resorting to spending more money. 5. Reevaluation: after making a change, reevaluating the system to see where the Constraint is located. Inertia is your enemy: don’t assume engines will always be the Constraint: once you make a few Changes, the limiting factor might become windshields. In that case, it doesn
