A company can improve its cash inflow in the form of profits if Six Sigma is deployed systematically and in right areas. The Six Sigma experts continuously work on reducing the defects in order to reach a situation of zero defects in an organization. Six Sigma is applied in an organization in two methods, the DMAIC (Define, Measure, Analyze, Improve and Control) and the DMADV (Define, Measure, Analyze, Design, Verify) methods. The Six Sigma DMADV approach focuses on the process redesign based on the short falls. The DMADV technique works by developing different alternative models for quality improvement. The DMAIC technique focuses on process improvement in an organization. The DMAIC technique is used in an organization to rejuvenate the least effective process and product. This is focused on improving the future performance on making sufficient improvement in the current activity level. Six Sigma is an approach that is used in all sorts of business and other production areas where quality improvement is needed.
The quality of the Six Sigma approach has made many business entities including GE implement the process. This process includes Define the problem, Measure what you care about, Analyze or Statistically find root causes, Improve or Mobilize change initiatives, and Control or Sustain improvements (DMAIC). In the first phase, teams aim to identify the problems that are related to the business and business satisfaction. Efforts are taken to relate the customer issues with the general business process by the factors of CTQ. In order to get the total result of the process the team establishes project charters, identifies the required resources, and finds the leadership approvals. In the next phase the team identifies the deficiencies of the current process and takes remedial measures. A good understanding of the customer expectations is made possible to establish the out of specification conditions. The characteristic feature of the Six Sigma process of GE is that even the beginners are able to meet the challenges of acquiring the concepts and that the time required for complex calculations is made the minimum possible. In the third phase, the root causes of the present defects are identified by the analysis based on which prioritized list of factors influencing the expected result is prepared. For this, various tools like multivariate analysis, test for normality, ANOVA, correlation, and regression etc are made use as the tools. In the next phase, teams seek out best possible solution and build up a plan action to implement the solution. On the basis of the test to confirm the solution, the process is modified and the effect of the result is analyzed. In the final stage, control charting techniques are used in order to improve the current measures. The measures adopted in this stage help to check the possible recurring of the problems. In this stage the approach leads to long term payoffs in quality and monetary terms. The GE employees are trained effectively in this process and the teams are able to check the business problems applying the concepts of the program to the problem.
