B. Lean Foundations and Principles:

Describe the purpose of lean (waste elimination) and its methodologies (just-in-time, poka-yoke, kanban, value stream mapping). Describe the value of lean to the organization as a whole. (Understand)

C. Six Sigma Roles and Responsibilities:

Define and describe the roles and responsibilities of Six Sigma team members (i.e., individual team members, Yellow Belt, Green Belt, Black Belt, Master Black Belt, process owner, champion, sponsor).

D. Quality Tools and Six Sigma Metrics

1. Quality tools

Select and use these tools throughout the DMAIC process: Pareto charts, cause and effect diagrams, flowcharts, run charts, check sheets, scatter diagrams, and histograms. (Apply)

2. Six Sigma metrics

Select and use these metrics throughout the DMAIC process: defects per unit (DPU), defects per million opportunities (DPMO), rolled throughput yield (RTY), cycle time, and cost of poor quality (COPQ). (Apply)

✅Module-2: DEFINE PHASE

A. Project Identification:

1. Voice of the customer

Define the voice of the customer and describe how customer needs are translated into quantifiable, critical-to-quality (CTQ) characteristics. (Understand)

2. Project selection

Describe how projects are identified and selected as suitable for a Six Sigma project using the DMAIC methodology. (Understand)

3. Stakeholder analysis

Identify end users, subject matter experts, process owners, and other people or factors that will be affected by a project, and describe how each of them can influence the project. (Understand)

4. Process inputs and outputs

Use SIPOC (suppliers, inputs, process, outputs, customers) to identify and define important elements of a process. (Apply)

✅Module-3: MEASURE PHASE

A. Basic Statistics

Define, calculate, and interpret measures of central tendency (mean, median, mode) and measures of dispersion (standard deviation, range, variance). (Apply)

B. Data Collection

1. Data collection plans

Describe the critical elements of a data collection plan, including an operational definition, data sources, the method to be used for gathering data, and how frequently it will be gathered. Describe why data collection plans are important. (Understand)

2. Qualitative and quantitative data

Define and distinguish between these types of data. (Understand)

3. Data collection techniques

Use various data collection techniques, including surveys, interviews, check sheets, and checklists to gather data that contributes to the process being improved. (Apply)

C. Measurement System Analysis (MSA)

1. MSA terms

Define precision, accuracy, bias, linearity, and stability, and describe how these terms are applied in the measurement phase. (Understand)

2. Gauge repeatability and reproducibility (GR&R)

Describe how and why GR&R is used in the measurement phase.

✅Module-4: ANALYZE PHASE

A. Process Analysis Tools

1. Lean tools

Define how 5S and value analysis can be used to identify and eliminate waste. (Understand)

2. Failure mode and effects analysis (FMEA)

Define the elements of severity, opportunity, and detection, and determine how they are used to calculate the risk priority number. Describe how FMEA can be used to identify potential failures in a process. (Understand)

B. Root Cause Analysis

Describe how the 5 Whys, process mapping, force-field analysis, and matrix charts can be used to identify the root causes of a problem. (Understand)

C. Correlation and Regression

1. Correlation

Describe how correlation is used to identify relationships between variables. (Understand)

2. Regression

Describe how regression analysis is used to predict outcomes. (Understand)

D. Hypothesis Testing

Define and distinguish between hypothesis terms (i.e., null and alternative, type I and type II error, p-value and power). (Understand)

✅Module-5: IMPROVE & CONTROL PHASE

A. Improvement Techniques

1. Kaizen and kaizen blitz

Define and distinguish between these two methods and describe how they can be used to make improvements to any process in an organization. (Understand)

2. Plan-do-check-act (PDCA) cycle

Define and distinguish between the steps in this process improvement tool. (Understand)

3. Cost-benefit analysis

Explain the importance of this analysis and how it is used in the improve phase. (Understand)

B. Control Tools and Documentation

1. Control plan

Describe the importance of a control plan for maintaining improvements. (Understand)

2. Control charts

Describe how X-R charts are used for monitoring and sustaining improved processes. (Understand)

3. Document control

Describe the importance of documenting changes to a process and communicating those changes to stakeholders. (Understand)
