In every manufacturing process, quality control is very important. In fact, it is one of the most important aspects of manufacturing. After all, this determines the success of the manufacturing process. Quality control is the process of ensuring the quality of a product. The least requirements that quality control should meet are the minimum requirements and specifications of a product. However, it is also necessary that the product is satisfactory, dependable, and fiscally sound. In order to ensure that products meet the standard requirements and are satisfactory, a thorough examination of these products is done. Whenever there are problems identified, the production of such products are temporarily stopped until such time that these problems are rectified.
The process of quality control does not start and end with the finished product, but rather starts as soon as the production process begins. Here are the various stages in which quality control is observed:
Receiving of Raw Materials. This is probably the most critical stage of quality control. According to one of the famous quotations, “all that ends well starts well". This is practically true because all end products are dependent on the raw materials. It is therefore essential to carefully examine and check the raw materials and make sure that these materials meet the standards and requirements.
Production Process. Every stage of the production process is as equally important as the other. Since most production stages are interdependent with one another, the assurance that every stage is correctly done is very necessary.
End Product. The end product manifests the correctness of the various production processes that it underwent. However, this does not guarantee the quality of the product; such that the need for further inspection of the product is necessary. When all the requirements are satisfied, then quality control is achieved successfully.
Various manufacturing companies have exerted money, time, and manpower on quality control. This is so because these companies believe that quality leaves a mark. Whenever products are of quality, there is no fear of its marketability. The marketability of the products would sustain the production in return. Therefore, if we come to analyze it, production, quality control, and marketability are all related to one another. In other words, quality control dictates the success of a product that results into customer satisfaction.
Therefore, if quality control is important, then measures that would ensure quality control are as equally important as well. Correspondingly, the problems that may challenge quality control are also very important. The typical problems that are encountered in quality control are: deviations from the specifications; and the variance around target specification. These problems should be anticipated by the management and should be prepared for. Fortunately, methods provided in quality control are able to address these problems.
These methods include on-line and in-process procedures. There procedures aim to translate deviations and variances into charts which are more recognizable and easier to interpret. Furthermore, these charts will clearly show the amount of deviation and variance for earlier detection of production fault and for immediate rectification of the problem.
