![]() ![]() Statistical methods are again used to assess improvement. Often, other lean methods such as cellular manufacturing, 5S, mistake-proofing, and total productive maintenance are identified as potential solutions. Improve. Here, implementation of creative solutions - ways to do things better, cheaper, and/or faster - that address the problems identified during the analysis phase takes place.Analyze. This phase is concerned with identifying the root cause(s) of quality problems, and confirming those causes using appropriate statistical tools.Metrics are established and used to obtain baseline data on process performance and to help identify problem areas. Measure. In this phase, the aim is to gather information about the targeted process. ![]() ![]() Define. This phase focuses on defining the project improvement activity goals and identifying the issues that need to be addressed to achieve a higher sigma level.Method and Implementation ApproachĪ sequence of steps called the Six Sigma DMAIC (Define, Measure, Analyze, Improve, and Control) is typically used to guide implementation of Six Sigma statistical tools and to identify process wastes and weaknesses. The statistical tools of Six Sigma system are designed to help an organization correctly diagnose the root causes of performance gaps and variability, and apply the most appropriate tools and solutions in addressing those gaps. Six Sigma has evolved among some companies to include methods for implementing and maintaining performance of process improvements. It is important to note that not all companies using Six Sigma methods are implementing lean manufacturing systems or using other lean methods. A Six Sigma quality level equates to approximately 3.4 defects per million opportunities, representing high quality and minimal process variability. A sigma quality level serves as an indicator of how often defects are likely to occur in processes, parts, or products. The term sigma is a Greek alphabet letter (σ) used to describe variability. Six Sigma was developed by Motorola in the 1990s, drawing on well-established statistical quality control techniques and data analysis methods. Six Sigma is also being used to further drive productivity and quality improvements in lean operations. Six Sigma's toolbox of statistical process control and analytical techniques are being used by some companies to assess process quality and waste areas to which other lean methods can be applied as solutions. Six Sigma consists of a set of statistical methods for systemically analyzing processes to reduce process variation, which are sometimes used to support and guide organizational continual improvement activities. Implications for Environmental Performance.Professional responsible for the business process that is the target of a Six Sigma project. Professional who has general awareness of Six Sigma (through no formal training) and who brings relevant experience or expertise to a particular project. Typically has two weeks of classroom training in methods and basic statistical tools. Part-time professional who participates on a Black Belt project team or leads smaller projects. Responsible for coaching/mentoring/training Black Belts and for helping the Six Sigma leader and Champions keep the initiative on track. Highly experienced and successful Black Belt who has managed several projects and is an expert in Six Sigma methods/tools. Typically has four to five weeks of classroom training in methods, statistical tools and sometimes team skills. Middle- or senior-level executive who sponsors a specific Six Sigma project, ensuring that resources are available and cross-functional issues are resolved.įull-time professional who acts as a team leader on Six Sigma projects. Senior-level executive who is responsible for implementing Six Sigma within the business. Senior executive who sponsors the overall Six Sigma initiative. Six Sigma Roles and Responsibilities Sponsor Candidates attend classroom training for a week, work on their projects for three weeks, return to class for another week, and so on until they have acquired all the skills appropriate to their role. At the “Belt” level, each candidate is assigned an initial “training project” that he/she will work on during the formal training period. Leaders and Champions usually receive high-level training on the technical aspects of Six Sigma and specific training on how to lead an initiative. The chart below describes how these roles are typically defined. Six Sigma has a martial arts convention for naming many of its professional roles. ![]()
