Скачать или смотреть WHAT IS THE THEORY OF CONSTRAINTS, AND HOW DOES IT COMPARE TO LEAN THINKING?

The Theory of Constraints is a methodology for identifying the most important limiting factor (i.e. constraint) that stands in the way of achieving a goal and then systematically improving that constraint until it is no longer the limiting factor. In manufacturing, the constraint is often referred to as a bottleneck.

The Five Focusing Steps (a methodology for identifying and eliminating constraints)

The Five Focusing Steps are further described in the following table.

StepObjectiveIdentifyIdentify the current constraint (the single part of the process that limits the rate at which the goal is achieved).ExploitMake quick improvements to the throughput of the constraint using existing resources (i.e. make the most of what you have).SubordinateReview all other activities in the process to ensure that they are aligned with and truly support the needs of the constraint.ElevateIf the constraint still exists (i.e. it has not moved), consider what further actions can be taken to eliminate it from being the constraint. Normally, actions are continued at this step until the constraint has been “broken” (until it has moved somewhere else). In some cases, capital investment may be required.RepeatThe Five Focusing Steps are a continuous improvement cycle. Therefore, once a constraint is resolved the next constraint should immediately be addressed. This step is a reminder to never become complacent – aggressively improve the current constraint…and then immediately move on to the next constraint.
