Focused improvement in the theory of constraints is an ensemble of activities aimed at elevating the performance of any system, especially a business system, with respect to its goal by eliminating its constraints one by one and by not working on non-constraints. Focused improvement can also be defined in simpler terms as a process that identifies the systems problems and then modifies the whole system in order to find the most cost effective, time saving and least disruptive solutions in order to optimize the system.
