The benefits brought by a Statistical Quality Control Certification
In today’s economic activity, the need to make the optimal use of resources for the manufacture of goods and services of high quality at a low cost and to market them at a competitive price has acquired great significance. Consequently, there has been a growing demand for persons trained in the techniques and approach of quality control. The Statistical Quality Control (SQC) process relates to the use of statistical methods of monitoring and control in order to reduce wastes in the production activity and make sure that confirming goods are being produced. Although this process has been mostly applied in the control of manufacturing lines, its applicability can be extended to any process with a measurable output.
In mass manufacturing, a post-manufacturing inspection of the products was usually being performed for assessing the quality of the finished articles and rejecting the ones that didn’t correspond to specifications. The great benefit brought by the Statistical Quality Control is the possibility to analyze the performances in the manufacturing process for predicting any variations that could result in the rejection of a product. Upon observing at the right time the deviations in the process that caused an undesired change, the persons responsible for the production line can identify the flaw and take the corresponding measures. For achieving these goals, quality professionals should make adequate use of statistical tools.
Statistical quality control can be divided into three categories. The first category is the descriptive statistics, meant to describe quality characteristics and relationships and makes use of tools such as the mean, standard deviation, the range and the measure of the distribution of data. The second category is the statistical process control involving the inspection of a random sample of the process’output and deciding whether it generates products that apply to a predetermined range of characteristics. Control charts are the most popular statistical tools for monitoring the quality of goods and services and detecting any unusual behaviours.
In order to do so, there are samples from the process taken every time interval and their quality is being measured in order to detect when the process goes wrong as early as possible. The third category relates to acceptance sampling, consisting in the random inspection of a sample of goods and deciding whether to accept the entire lot of such goods based on the results.
While descriptive statistics can describe the central tendency and variability of the observed data in terms of quality, they are not enough to evaluate if there is, indeed, a quality problem. Acceptance sampling can, on the other hand. It helps us decide if a batch of products meets the quality requirements and, subsequently, if it must be accepted or rejected. However, this decision can be made only after the completion of the manufacturing process and is not helpful when it comes to discover a quality problem during the process. This is why although all three categories are useful in evaluating the quality of products and services, the statistical process control tools are mostly used because they help finding quality problems during the production process.
