It is said that some experienced worker, without knowledge or statistical techniques, can create exquisite handicrafts by technical skills. Why is it? This is only because they have mastered the law. However, the law requires a lot of resources and energy to do better in life. If master the statistical techniques and then master the law by using statistical techniques, you can learn how to control product quality in a short period of time.

Recently I contact with the SPC and learn some relevant knowledge. The modern enterprise, especially production-oriented enterprises need to use SPC, the application of statistical techniques to detect problems in the process, analyze the causes and take measures to enhance process capability to ensure that the process in a controlled state. Stable process can ensure quality.

Application of statistical techniques can quickly access to the law. In the process control, statistical techniques can be found abnormal fluctuations in a timely manner, producers and managers to take prompt corrective measures, the eradication of substandard goods in the process, played a role in prevention. That is, from detection - tolerate waste removed unqualified goods, to prevent excessive - to avoid wasting the first time on doing a good job and thus greatly reduce the company's production costs.

How to avoid waste with the status of Bluestar? When production line products in question, we should try to avoid on-line loss, discover problems; analyze the general reasons or special reasons, specific to the workers the skills, materials defects, or products of the design problems. And to take appropriate measures. If the material is the result of the reasons for defects and production line workers mistakenly believe that is the reason, only to enhance the skills of workers, not to strengthen the control of materials. This will only futile. Causing unnecessary waste of the Department of the testing materials to achieve a reasonable arrangement, the non-conformity product testing and disposal of specific reasons, the treatment is given reasonable options. Otherwise they will only lead to bad stay bad pieces of the goods, the company's increasing costs. Logistics Department of product management, material requisitioning, procurement, testing, to the receipt, storage, to the material, to fill expected, to control every step of wear and tear are interlocking. And how the control of the first to do a good job, how to make use of SPC for statements of  Material needs of the next plan, to the request of the Department of supply procurement cycle, the minimum volume of delivery, economic quantities; QC to ensure that each procurement of materials and parts to the procurement cycle after the test, because some of the inspection cycle is too long may lay-off Expected to be the use of SPC control chart, the precipitation, machines, goods, materials, Central, measurement and focus on five main factors, can find a better countermeasures, such as the procurement of materials do not arrive in time, each capturing a very volatile On the elimination of a factor.
