For manufacturers who produce products that have a kind / type that much physically but has the same shape and size should always be careful with the product mix with each other. Because if that happens it will cause the customer’s claim and can lead to customer trust will decrease. Therefore, the nonconforming product wastage must be addressed.
Error on the product that is incompatible with the requested specifications will impact sustainable. As an example the case of the mobile phone companies who book the type of resistive plate resistor with value of 10 Milli ohms, in the same physical condition was the same resistive plate with resistive plate with a value of 5 Milli ohms and the mobile phone companies get 5 Milli ohms. If the check passes in a sense is not detected until the production process, the next thing happens is not functioning properly due to mobile phones from the factory resistor supplier’s specifications. If it so the loss will be suffered by the mobile phone companies because their products would have to be discarded or thrown into the market if forced to reduce the customer trust.
Defective product just as the above case if it reached the hands of consumers, brand mobile phones in question will also defective in terms of reputation that could disrupt the stability of the company’s business in the future.
Nonconforming product from the standpoint of lean manufacturing is the waste which must be immediately taken action. Nonconforming product will have implications on the performance of other workers. It also will affect the performance of other machines. Some examples of nonconforming product that can be detected in the production area for example;
– Product incompatibilities with the specifications provided by customer
– Of mixing products with one another so that in one package that should contain a specification into two or more
Identify the problem nonconforming products must be supervised from start in the form of material. The sooner we know the product mix at the beginning it will be sooner or removal decision-making of these products so as not to go into production. Some things to watch in case of non-conforming product;
1. Material defects
2. Imperfect Finish
3. Treatment inspection
4. Customer claims
In this case 5s remain a cornerstone in any action to trace the root causes of nonconforming product from the flow of material to finished products
