What is the theory of restrictions?
The theory of restrictions is a business philosophy presented for the first time in 1984 by Dr. Eliyahu M. Goldratt. In his novel objective , Goldratt suggests that productivity in any system is limited by restrictions or narrow spines that slow down several key processes. Goldratt refers to these souchers as a restriction from which it derives the name of its theory, and states that each system has at least one limitation limiting its maximum capacity. Its theory of restrictions offers a five -speed procedure designed to improve the efficiency, productivity and profitability of steering or by circumventing these restrictions, increasing the capacity of the whole system. Three measurements that attract its focus are permeability - usually defined in terms of sales, operating costs and stocks. He suggests that by monitoring its five steps, the permeability may increase when the operating costs and the inventory decrease, which will be more profitable.
The implementation of the theory of restrictions is a relatively simple process. The first stepM is, of course, identifying the only limitation, ideally the most restrictive narrow place in the whole system. Furthermore, in the GOLATTT process, it calls the "use of restrictions", the activities of the selected limited element are examined, with special attention to paying maximum efficiency focused exclusively on a single primary function, ensuring that the effort concerning the task is not lost.
In the next step, Focus moves away from restrictions on activities and processes that are delayed or unconnected resources. Rather than slow down these elements so that they correspond to the tempo limit, the time from these other sources is subordinate to help overcome the restriction limitations. Within this system, the elements of previously left to inactivity would move to a secondary task, helping to reduce restrictions. For exampleThey could help with the production or packaging to speed up production.
After this subordination, it is necessary to determine whether productivity has been sufficiently increased. If not, more drastic changes may be required to increase the capacity of restrictions. Once the obstacle is overcome and no longer slows down the rest of the system, it is no longer a limitation. The last step in using the theory of restrictions is to return to the first step and identify a new restriction.
