![]() ![]() The collection of information on the current situation. The five DMAIC process steps of any Six Sigma Project add the discipline and common language that propels the process forward.ĭetermines the scope and purpose of the project and includes a Project Charter, a process map of the problem to be investigated and an analysis of customers to determine the Voice of the Customer (VOC), resulting in Critical to Quality variables, or CTQs (sometimes CTC, Critical to Customer). The project management component of this process is particularly important. In addition to the methodology training, learning topics that enable the organization to use Six Sigma to its fullest capability include change management, teamwork, creativity, problem-solving, project management, statistics, process improvement and design of experiments. Organizations often begin with an overview of Six Sigma that generates understanding of the concept, strategy and targeted results. Six Sigma preparation spans a broad range of learning and training topics. This has the benefit of signaling to all organization members that top-level commitment exists and executives expect all employees to be on board and embrace the new initiative. On the other hand, many successful implementations have launched an enterprise-wide training plan. Along with the executive preparation, selected Green Belt and Black Belt training for those who are involved in an initial project will allow a greater chance of success with the first set of projects. A blended approach starts with an executive overview to encourage top-level commitment. Should an organization train all employees or start slower with targeted employees? One danger of the top-down, full-training approach is that by the time it reaches the Green Belts actually doing the project work, middle and upper managers may be discouraged by the lack of progress. Two areas of concern will be the cost and the amount of learning and training. Training activities have evolved to a set of generally accepted levels known as Yellow Belts, Green Belts, Black Belts, Master Black Belts and Champions, defined later, who all contribute increasingly complex levels of capability in Six Sigma process and management. ) Six Sigma requires training of key personnel involved in the projects and oversight management of the program. ![]() ![]() To ensure that the process works, a series of steps is undertaken in every Six Sigma project: Define, Measure, Analyze, Improve and Control, commonly referred to as DMAIC. If mail delivery were at the 6 sigma level, the result would be the loss of seven pieces of mail each hour. daily mail delivery at the 4 sigma level would result in the loss of 0,000 pieces of mail each hour. The breakthroughs occur when a process is improved to the 6 sigma level, almost perfect quality. Moving from 3 to 4 sigma could be classified as continuous improvement. (See Table 1.) It is common to find 3 to 4 sigma levels in many manufacturing processes, and or 3 sigma in transactional businesses. A sigma of 6 translates to 3.4 defects per million opportunities. After defining which performance measures represent Critical to Customer (CTC) requirements, data are collected on the number of defects and then translated into a sigma number. The ultimate goal is to eliminate defects and errors and the costs associated with poor quality. The lower the variation in a process, the fewer defective parts or service transactions are produced, and the higher the Sigma number. Sigma refers to the Greek symbol (s) that represents the amount of variation in a process. Six Sigma is a data-driven, methodical program of continuous and breakthrough improvement focused on customers and their critical requirements. What does this enterprise-wide methodology demand from corporate learning organizations? Employees are utilizing Six Sigma skills to drive quality improvement in functions ranging from manufacturing and engineering to purchasing and human resources. ![]() In recent years, popularized by General Electric, Allied Signal, Sony, DuPont and others that tell a tale of dramatic quality improvement and change, Six Sigma is at the forefront of quality initiatives commanding CLOs’ attention and learning resources.īecause of the rigorous methodology imposed by Six Sigma, learning and training organizations become heavily involved with preparing employees for Six Sigma. In the 1980s, major corporations like Motorola, Digital Equipment, Boeing and Xerox rallied around the quality concept of Six Sigma. The appearance of “quality” topics originated as early as the 1950s when Deming’s teachings surfaced. ![]()
