Six Sigma (DMAIC)
Six Sigma is not what it used to be; it has evolved throughout the centuries and become what it is today. According to the article, The History of Six Sigma, Carl Fredrick Gauss (1777-1855) introduced the normal curve and six sigma as a measurement standard that can be traced back to him. As a measurement standard, six sigma is traced back to Walter Shewhart who explained that three sigma is the point where a process needs correction. There were many measurement standards that were later introduced, but the recognition for the term “six sigma” goes to a Motorola engineer named Bill Smith. (Page 1) Motorola ended up copywriting the term in their organization.
According to The History of Six Sigma, Motorola engineers determined quality levels did not provide enough granularities. Geoff Tennant explained in his book Six Sigma: SPC and TQM in Manufacturing and Services: "Six Sigma is many things, and it would perhaps be easier to list all the things that Six Sigma quality is not. Six Sigma can be seen as: a vision; a philosophy; a symbol; a metric; a goal; a methodology." There has been a lot of progression with Six Sigma over time. It has become more like a quality system like TQM, total quality management, or ISO, International Organization for Standardization. (Page 1) There have been a few industries that are involved with the history of Six Sigma. Motorola is one, along with Allied Signal, and General Electric. According to www.beexcellence.org, Bossidy, who was top management at Allied Signal, generated significant improvements with Six Sigma. Lawrence Bossidy was at General Electric, but left in 1991. Allied Signal improved both the effectiveness and efficiency of Six Sigma by focusing on customer measures of effectiveness. They saved millions of dollars and improved customer reputation. There was no cost-cutting through downsizing or lay-offs with these improvements. (Page 1) Jack Welch, who worked at General Electric, asked to team up with Allied Signal. According to www.beexcellence.org, General Electric made Six Sigma a corporate-wide initiative. It became the formal support and active involvement in management. General Electric also used Six Sigma to improve effectiveness and efficiency. (Page 1) There are five different phases that are included in Six Sigma. These five phases follow the DMAIC principle of problem solving and include define, measure, analyze, improve and control. In each of these phases are implemented differently and each of the five phases’ methodology is different as well. According to Insyte Consulting, the first step is define; explain when we should use Six Sigma. This includes defining your problem. In order to do this, we need to ask some basic questioning and analyzing the current situations. There is a fundament understanding that is gained when we choose the correct methodology to solve problems. After it is decided that it is necessary to utilize Six Sigma, there are a few key elements that are used to ensure success. These key elements include: 1. prioritizing opportunities for improvement; 2. selecting appropriate projects from the data collected and management’s acceptance; and finally 3. recruiting a team that will compromise to find a solution. In this first phase of Six Sigma, it is the critical time to determine if this is the correct way to solve the problem. “If you properly define the problem, you define the proper course of action, resulting in a bigger return on investment spent to solve the problem.” (Page 1-2) The second phase in Six Sigma is measure, which is considered the critical phase. In this phase you need to describe the current state of the process/system. According to Insyte Consulting, in this phase a detailed process map can be created. This process map is a detailed flow chart, or outline, of how the process is operated. In this phase we can also ask ourselves, “Do we have valid data?” During this time you...
