Quality and Inspection (continued)
Feb 23, 2018


Many of the quality systems of the past were designed with the objective of sorting good products from bad products during the various processing steps. Those products judged to be bad had to be reworked to meet specifications. If they could not be reworked, they were scrapped. This type of system is known as a “detection correction” system. With this system, problems were not found until the products were inspected or when they were used by the customer. Because of the inherent nature of human inspectors, the effectiveness of the sorting operations was often less than 90%. Quality systems that are preventive in nature are being widely implemented. These systems prevent problems from occurring in the first place by placing emphasis on proper planning and problem prevention in all phases of the product cycle.

The final word on how well a product fulfills needs and expectations is given by the customers and users of that product and is influenced by the offerings of competitors that may also be available to those customers and users. It is important to recognize that this final word is formed over the entire life of the product, not just when it was purchased.

Being aware of customers’ needs and expectations is very important, as was previously discussed. In addition, focusing the attention of all employees in an enterprise on the customers and users and their needs will result in a more effective quality system. For example, group discussions on product designs and specifications should include specific discussion of the needs to be satisfied.

A basic commitment of management should be that quality improvement must be relentlessly pursued. Actions should be ingrained in the day-to-day workings of the company that recognize the quality is a moving target in today’s marketplace driven by constantly rising customer expectations. Traditional efforts that set a quality level perceived to be right for a product and direct all efforts to only maintain that level will not be successful in the long haul. Rather, management must orient the organization so that once the so-called right quality level for a product has been attained ,improvement efforts continue to achieve progressively higher quality levels.

To achieve the most effective improvement efforts, management should understand that quality and cost are complementary and not conflicting objectives. Traditionally, recommendations were made to management that a choice had to be made between quality and cost, because better quality inevitably would somehow cost more and make production difficult. Experience throughout the world has shown that this is not true. Good quality fundamentally leads to good resource utilization and consequently means good productivity and low quality costs. Also significant is that higher sales and market penetration result from products that are perceived by customers to have high quality and performance reliability during use.
