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...

An organization's success depends upon how it delivers on its processes. Before Black Belts can begin to improve an organization's processes, they must measure those processes with the appropriate data. The crucial steps of data collection and measurement precede process improvement in any Six Sigma initiative. Successful data collection starts with careful planning; a knowledge of various data types, sampling strategies, and measurement methods; and an ongoing awareness of best practices for ensuring data accuracy and integrity. Only reliable and suitable data will yield...

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...

"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...
Overview/Description
Six Sigma teams concluding the Analyze phase with a well-understood problem strive in the Improve phase to generate a well-designed solution. Design of experiments (DOE) is a controlled approach to experimentation that enables teams to systematically change the level of one or more input factors and observe the effects on the targeted response. If teams exercise care in choosing the right design â including suitable factors, levels, and responses â their experiments can reveal the precise combination of factors that will optimize the response. Later, that combination...
Overview/Description
Successful organizations are founded on effectively developing and deploying strategic plans. Organizations must identify their primary goals and objectives based on their mission and vision statements. Other success factors include understanding market forces, internal strengths and weaknesses, stakeholders, relevant technology, and legal and regulatory factors. With these considerations, an organization's action plan can be developed and deployed, and its effectiveness evaluated. This course explores the concepts of strategic planning models, business environmental...

A project charter is the most important document used to initiate and manage a Six Sigma project, and it is treated as an informal contract between an organization and the Six Sigma team. The project charter articulates the problem that the Six Sigma team is going to work on, and the project's scope, goals, and objectives in very clear, specific, and measurable terms. As part of the process of developing a project charter, some performance measures such as cost, revenue, and schedule are identified and developed. Once the project is kicked off, its progress is measured...
Overview/Description
Though a successful approach to error reduction and process improvement, Six Sigma can be difficult to implement and is not ideally suited to every business or task. This Challenge weighs the benefits of adopting Six Sigma and under what circumstances it is best applied.

Overview/Description
Evaluating the performance of your suppliers and maintaining mutually fulfilling relationships with them are essential activities in supplier relationship management. There are many types of supplier-related problems that you may have to deal with, and effective purchasing personnel use key performance criteria to analyze and track their suppliers' performance. Analysis of supplier performance can help you ensure that your company is getting the best value and service from suppliers, and detect areas in which corrective action needs to be taken. Effective performance...
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...
