Discuss quality tools and techniques that can be used to improve quality. Specifically describe the difference between inspection vs. poka-yoke as a quality assurance method. How do these methods relate to Ishikawa's "The Basic Seven" and statistical methods of quality control?
What will be an ideal response?
Tools and techniques, and procedures needed to ensure high-quality products and services once the business is committed to continuous improvement is needed. A combination of methods based on the company's industry and product can be used to achieve this improvement.
*TQM is an approach that embodies management's commitment to providing high-quality products and services. It emphasizes continuous improvement.
*Inspections, the traditional method of maintaining quality control, consist of examining a part or product after it has completed a process to determine whether or not it is acceptable. Attribute and variable inspection are variations of this method.
*The Basic Seven are quality tools (cause-and-effect diagrams, check sheets, control charts, histograms, Parento charts, scatter diagrams, and flow or run charts) that can solve 95% of a company's quality problems according to its founder, Kaoru Ishikawa.
*Poka-Yoke is a more proactive approach that seeks to mistake-proof a firm's operations. Potential problems are identified and hopefully designs are changed before the product is made.
*Acceptance sampling is a statistical method that involves taking random samples of products and measuring them against predetermined standards. Sampling error as well as the use of attribute or variables should be decided before using this method.
*ISO 9000 certification, while difficult to achieve, reflects the highest level of quality management. The certification is an international recognition for a company's efforts.
Ishikawa's Basic Seven are tools that can be incorporated into any of the techniques. These tools help a firm collect and analyze data relating to quality to determine areas for improvement.
