What distinguishes Six Sigma from traditional continuous improvement?
|
Six Sigma represents a well-thought-out packaging of quality tools and philosophies in an honest effort to provide rigor and repeat ability to quality improvement efforts. Second, Six Sigma is much more cost-reduction-oriented than traditional continuous improvement. While this makes it popular with CEO's many quality practitioners are uncomfortable with the focus on results since it violates several of Deming's points. The third fundamental nuance of Six Sigma is the way it is organized around creating champions, black belts, green belt sand in some situations, yellow belts. Fourth, Six Sigma and lean production have been combined into an approach termed
|
|
|
What are the titles and roles of the key players in Six Sigma efforts?
|
Thetitles are champion, master black belt, black belt, and green belt. Thechampion works with the black belts and potential black belts to identifypossible projects. Depending on the size of the company, the champion residesat the CEO or VP level. The champion acts as a funnel for project ideas anduses Pareto analysis to analyze ideas and determine where the best return oninvestment lies. The champion also provides continuing support for the projectand validates results at the end.Themaster black belts are experienced black belts (and may not exist in smallercompanies).Masterblack belts serve as mentors and trainers for new black belts and serve as away to bring training in-house.Theblack belts are the key to Six Sigma and are individuals that are speciallytrained, generally at a cost of $10,000 to $16,000 for a period of about 4months. Upon completion of training, these individuals are committed to full-time cost reduction projects. The black belt is a specialist and it is not feasible for a firm to have many black belts.Greenbelts are trained in basic quality tools and work in teams to improve quality.They are assigned part-time to work on process and design improvement.

|
What is robust design and what are the different types of design that compose it?
|
The concept of robust design is that products and services should be designed so they are inherently defect-free and insensitive to random variation. Robust design may be achieved by concept design, parameter design, and tolerance design. Concept design is the process of examining competing technologies to produce a product and includes process technology and design choices.Parameter design refers to the selection of control factors and the determination of optimal levels for each of the factors. Control factors are those variables in a process that management can manipulate.Tolerance design deals with developing specification limits and occurs after parameter design has been used to reduce variation and the resulting improvement has been insufficient.
