These rules help to underline an essential observation in the theory of constraints: “a local improvement does not necessarily lead to a global improvement”. Establish programmes taking into account all constraints simultaneously.Bottlenecks determine both output and stock levels.Without repeating them all here, these rules include :
THEORY OF CONSTRAINTS FULL
These rules are intended to emphasise the importance of removing constraints and making full use of bottlenecks. In addition to these key steps, there are 9 rules in the theory of constraints that must be followed.

In this way, we are in a continuous improvement process. The bottleneck will move, so it is important to regularly reassess the constraints and their impacts. It is then a matter of seeking additional resources, offloading the bottleneck to other resources if possible, or investing to improve the bottleneck capacity. This step is necessary if the capacity of the constraint is not sufficient even after the improvements. The next step is to ensure that all other resources are aligned with the bottleneck station. To ensure this, the Drum-Buffer-Rope principle can be used. Make all processes subject to the constraint For example, it may be advisable to place a quality control in front of the bottleneck station to ensure that all parts passing through the bottleneck station are in order.ģ. It may take the form of an unskilled operator or an administrative queue.ĭuring this stage, the aim is to maximise the throughput of the bottleneck. On the other hand, a non-production constraint is more complex to identify. Identifying the constraint is relatively easy when it is an expensive or complex machine because, as we have seen, it is usually accompanied by a large amount of work in progress. The theory of constraints will seek to find the bottleneck in the system and then exploit it in such a way as to maximise the throughput of the whole system.

The first step is to identify the constraint. Clear explanations supplemented by examples and case studies define how the theory works, why it works, what issues are resolved, and what. Whatever the nature of the constraint or bottleneck, the Theory of Constraints provides key steps to remove it. Theory of Constraints Handbook offers an in-depth examination of this revolutionary concept of bringing about global organization performance improvement by focusing on a few leverage points of the system. This case is usually accompanied by a large amount of work in progress at the bottleneck and a particularly low throughput at the bottleneck outlet. When the constraint is a key stage in the production chain, it is called a bottleneck. Regulations and standards that may limit a system in terms of volume or time of use.Resources that are expensive or scarce.Company policy which may impose rules that limit company performance.Knowledge and beliefs that can lead to inaccuracies in the perception or performance of a task.

There are different types of constraints. What is a constraint?Ī constraint is a factor that limits the performance of a process. If this were not the case, the performance obtained would be maximum, which is impossible. The theory is based on the following observation: every system is subject to a constraint that limits its performance. The Theory of Constraints is a Lean Manufacturing philosophy that seeks to maximise the throughput of a production process.
