The content of The Goal revolves around the character Alex Rogo, a production manager responsible for saving the life of a losing factory. In addition, Rogo must find a way to save his marriage on the verge of breakdown. In that situation, Rogo discovered the “Socrates Method” and used it to settle the marriage problem. Then, he applied this method to the staff at the factory and quickly worked with them to find a solution.
“Theory of Constraints” is also clearly explained by Goldratt in The Goal. According to this theory, “the strength of a chain is the strength of the weakest link”. The collective strength will depend on the individual, as the smooth functioning of the system will depend on the individual components.
