Body of Knowledge Area Breakdown:

History of Six Sigma
Should be able to define Six Sigma and have an understanding of the history of Six Sigma and why it is used in business today.

y = f(x)
Although Six Sigma talks a lot about statistical analysis and measurements and various other mathematical applications, at the core of the process is one simple equation.  Understand the basic function of y=f(x)

Process Variances
Should have a basic understanding of identifying where variances are occurring in a function.

TQM & others
Have an understanding of the other process improvement methodologies and how they differ from Six Sigma.

Recognizing opportunities
Understand Six Sigma philosophies and how to recognize opportunity.

Managing Quality
Understand how to frame quality into what is important to the customer.

Deciding to start a Six Sigma project
Understand the “how and why” regarding a company launching a quality improvement initiative like Six Sigma.

Organizational Roles and Responsibilities
Understand how team are formed and the role of each belt level within the Six Sigma project.

The DMAIC Method
Understand and define DMAIC.  Define, Measure, Analyze, Improve, Control.

Why is DMAIC used
Understand why the DMAIC process is utilized.

DMADV variation
Understand the basis of DMADV (Design for Six Sigma) when you do not have an existing system or process to improve upon.

Project Communication
Understand why continual communication is critical to the success of the project.

Supporting Delivery
Understand the critical role that a Yellow Belt, or “Subject Matter Expert” plays within the Six Sigma team.

Defining a process
Determine how to define a process.  Process owners, scope and boundaries.

Critical to Quality Characteristics
Understand Critical to Quality (CTQ) measures.

Cost of Poor Quality (COPQ)
The Cost of Poor Quality is the sum of internal and external failures.  Understand the cost of poor quality.

Six Sigma Metrics
Understand the Sigma level, RTY, DPU, DPMO, FPY.  Consequential metrics, Quality Metrics, Cost Metrics, Scheduling Metrics.

Estimating the Baseline
Understand the process to estimate the baseline.

The Define Stage
The Project Definition and scoping of goals and objectives.  How the process is defined in terms of stakeholders, and the functionalities of the process.

The Measure Phase
Getting more detail into the process, what metrics and measurements are involved as well as estimating the baseline of the current “as is” process.

Six Sigma Tools
Understand the different tools that may be useful throughout the many parts of the Six Sigma project.

The Analyze Phase
Understand the value stream proposition and analysis.  Determination of the factors that influence the process output.

The Improve Stage
Understand how the new process is defined, potential benefits examined and verification of the new process determined.

The Control Stage
Understand the standardization of new practice, verifying the impacts /savings, and how to document lessons learned.

Valuing Six Sigma
Understand the role, like activities of a Green Belt and how that differs from a Black Belt.  Understand the communication project tasks that a Green Belt will likely be asked to undertake.
