All companies practice a certain process control procedure which ensures the quality of their services and products. Most definitely this procedure differs among companies but they all have one purpose and that is for the overall improvement of products and services. Some of these procedures are control limits in items, quality checks and test run for services and goods. The more control procedures a company practices, the better services and goods they offer to clients.
Among the most common type of process control procedure is observation. In this kind of procedure, the company assigns a certain person who oversees the production of items. This kind of procedure is time consuming and most of the time not a hundred per cent accurate since it relies on the observation of the designated person. However, this also works well on products which are easily observable. In some companies, the person in-charge with this work uses a certain customized tool to know if the product meets the standards or not.
