Improving Quality Of Production And Manufacturing Using Acceptance Sampling

By Patty Goff


Numerous questions have been fronted on the ways organizations designs and implements strategies to ensure that its products are compliant with the set standards. This is often done by most organizations through checking inputs. Information obtained is further compared with their own set quality standards and generated information is used for certificate analysis. This is significant in either accepting or rejecting the shipment. The usage of acceptance sampling as fronted by MIL STD is often implemented in most organizations.

Other organizations might also prefer the use of modern sampling procedures fronted by ANSI (American National Standards Institute) and ASQ (American Society for Quality). Regardless of the approach utilized, most quality assurance professional asserts that appropriate method should aims at minimizing inspection costs, preventing the entry of low quality materials from the organization production process and risk management.

Most quality professional views this strategy as just another inspection tool. It is essential to expand resource inspection to better production by inspection of critical received goods. By not inspecting such materials, the organizations might just basically cross their corporate fingers with a hope that their products will meet the set standards.

It occupies a middle ground between no inspection and a hundred percent inspection. These techniques have been viewed just as another set of inspections tools. In addition, most quality professionals confers the strategy as unworthy of being associated with quality improvement tool as the end result of all such statistical is a stand alone, meek accept or reject conclusions. Such assertion was perceived to be true however, in the recent times; such sampling strategy has been deemed to be more effective means of improving quality.

For instance, when the company inspector employs such strategy in tracking incoming materials and products such data obtained are further used in decision making on rejecting or accepting conclusion. This strategy makes it easier to notice the actual defects and failures along with the codes of the product, the name of the supplier, traceability elements associated with the supply. This information could not be easily obtained if the inspector used ANSI/ASQ Z1.4.

This strategy makes it possible to access historical data from the suppliers, products and denoting traceability elements. Professionals ascertain that such quality information can only be obtained through sampling strategy. By doing so, Pareto charts, histograms, control charts, as well other statistical analysis can be achieved through analyzing the inspection data.

Such critical information can be used to compare the defects between products supplied by different suppliers. A confirmation of lack of control or control by the supplier on the production process can also be made. Vendors can be able to improve the quality of supplied products and manufacturing processes through collaborating with the suppliers.

This approach serves as a compliment strategy for improvement of quality using the accept or reject conclusions. Previously, unknown vendors could just quantify their products and such information used in cost reduction in the supply chain and quality improvement. Alternatively, it can be done at a little or no cost to organizations which have already implemented the use of ANSI/ASQ measures.
