Basics of Six Sigma Projects and Teams

Overview/Description "Effective leadership is putting first things first. Effective management is discipline, carrying it out," says famous motivator and author, Stephen R. Covey. Six Sigma needs both effective leadership and management to deliver its promised results to an organization. It requires all Six Sigma leaders – Master Black Belts, Black Belts, and Green Belts – to effectively lead project teams to deliver their expected results. Understanding team building processes, tools, and role structures helps Six Sigma team members produce desired results and resolve negative team...

Data Classification and Collection in Six Sigma

Overview/Description "Measure what is measurable, and make measurable what is not so" said Galileo Galilei, the famous Italian physicist, mathematician, astronomer, and philosopher. Measuring the key characteristics in your current processes is a very significant step in any Six Sigma improvement journey. As such, sample data from existing processes needs to be identified, collected, presented, and analyzed. Collecting data that is correct and useful is one of the first steps in the measurement process. Various types of data exist, and they all need appropriate treatment during the collection...

Design for Six Sigma in the Organization

Overview/Description Design for Six Sigma (DFSS) is often called the future of Six Sigma, as it is emerging as a strategy that better serves the current innovation initiatives of many industries. DFSS uses a "pay me now or pay me later" approach by spending more effort and time on process or product design up front to avoid spending time and effort in those areas later. Whereas Six Sigma just focuses on improving existing designs at a later stage, DFSS focuses on creating new and better products and processes from scratch. It designs virtually error-free products and services from the very...

Design of Experiments and Validation of Solutions in Six Sigma

Overview/Description "We are, I think, in the right road of improvement, for we are making experiments," said Benjamin Franklin. In the Improve stage of the DMAIC process, Six Sigma teams design and conduct experiments to study the nature of relationships between input variables and the response variable(s). They do this by controlling and changing the input variables and observing the effects on the response variable(s). After determining what and how much needs to be changed to meet the desired improvement, teams generate solution ideas to optimize the response, and then the ideas are...

Exploratory Data Analysis in Six Sigma

Overview/Description In the Analyze stage of the Six Sigma DMAIC process, you closely examine the output variable (known as y) and its possible causes or input variables (known as x's) collected in the Measure stage to get a deeper understanding of their relationships. The goal of this analysis is to narrow down the many possible x's identified earlier during the Measure stage, to a few probable ones. This analysis is generally conducted through the use of two important toolsets: exploratory data analysis and hypothesis testing. Methods and tools used in these broad toolsets help to identify...

Hypothesis Tests for Variances, Proportions, ANOVA, and Chi-Square in Six Sigma

Overview/Description The hypothesis test is one of the most important tools used in the Analyze stage of the Six Sigma DMAIC methodology. A hypothesis test helps to determine whether or not an observed relationship or difference truly exists between inputs and outputs identified in the earlier stages of the process. Six Sigma teams are interested in determining whether this relationship or difference is due to random chance or if it is a true difference. If it is a real difference, Six Sigma teams like to determine if it has practical significance. The goal of this course is to explore...

Introduction to Hypothesis Testing and Testing for Means in Six Sigma

Overview/Description The Analyze phase in Six Sigma closely examines the many process inputs identified in the Measure phase to determine if they are related to outputs, and if a relationship does exist, if it is statistically significant. An important tool for this analysis is hypothesis testing. Hypothesis testing uses statistical analysis to determine if the observed relationship between two or more samples is real or due to random chance. A variety of tests are used to find statistical evidence to reject or "not to reject" a hypothesis. Once this is accomplished, the Six Sigma team is...

Measuring Process Capability and Performance in Six Sigma

Overview/Description Businesses exist to meet the needs of the customers they serve. As such, you must listen to the voice of your customers and build processes that deliver products and services to them. It is also necessary to review processes to ensure they remain within the targets and specifications set by your customers. Measuring the capability and performance of a process is an important activity in Six Sigma DMAIC methodology. Six Sigma teams use process capability and performance measurements, such as process capability (Cp), process capability index (Cpk), process performance (Pp...

Mentoring Six Sigma Green Belt (SSGB)

Overview/Description SkillSoft Mentors are available to help students with their studies for the Six Sigma Green Belt (SSGB) exam. You can reach them by entering a Mentored Chat Room or by using the E-mail My Mentor service. Target Audience Individuals who are studying the associated SkillSoft content in preparation for, or to become familiar with, the skills and competencies being measured by the actual certification exam. Prerequisites Familiarity with the exam objectives listed below and skills and competencies being measured in the associated certification exam. Expected Duration (hours)...

Modeling and Analyzing Processes in Six Sigma

Overview/Description "If you can't describe what you are doing as a process, you don't know what you are doing," says W. Edwards Deming, a well-known American quality advocate, statistician, and educator. During the Measure stage of the Six Sigma methodology, you need to identify and map processes and procedures for problem areas identified during the Define stage, and present them to the Six Sigma team for a closer look. As you start uncovering and analyzing these processes, the likely causes of problems become clearer. This course will examine the tools and techniques used to model and...
