The Executive Sponsor is a senior leader who champions Six Sigma initiatives across the organization. This individual provides strategic direction, allocates resources, removes organizational barriers, and ensures alignment with business objectives. They approve project charters and support cultural transformation.
The Deployment Champion oversees the entire Six Sigma program implementation. This person develops training programs, selects projects, tracks portfolio performance, and ensures methodology consistency throughout the organization. They bridge the gap between executive leadership and project teams.
The Project Champion or Sponsor owns specific improvement projects. They define project scope, secure necessary resources, eliminate roadblocks for the team, and communicate progress to stakeholders. This individual ensures the project delivers measurable business value.
Master Black Belts are technical experts who train and mentor Black Belts and Green Belts. They possess advanced statistical knowledge, facilitate complex projects, and develop organizational capability in Six Sigma methodology. They typically work full-time on Six Sigma initiatives.
Black Belts lead improvement projects full-time and serve as change agents within the organization. They apply DMAIC methodology, perform advanced statistical analysis, coach Green Belts, and drive significant process improvements that deliver substantial financial results.
Green Belts work on improvement projects part-time while maintaining regular job responsibilities. They support Black Belt projects or lead smaller-scale initiatives within their functional areas. Green Belts apply basic statistical tools and participate in data collection and analysis activities.
Team Members contribute subject matter expertise and process knowledge to projects. They participate in brainstorming sessions, collect data, implement solutions, and help sustain improvements over time.
Process Owners maintain improved processes after project completion, ensuring gains are sustained and standardized across the organization.

Why Six Sigma Roles and Responsibilities Matter
Understanding the roles and responsibilities within a Six Sigma framework is essential for successful project execution. Each role has specific duties that contribute to the overall success of process improvement initiatives. When team members understand their responsibilities, projects run more efficiently, communication improves, and organizational goals are achieved more effectively.
What Are the Key Six Sigma Roles?
Executive Leadership (Champions/Sponsors) These are senior executives who provide strategic direction and resources for Six Sigma initiatives. They remove organizational barriers, allocate budgets, and ensure alignment with business objectives. Champions select projects and assign Black Belts to lead them.
Master Black Belt (MBB) Master Black Belts are the highest level of Six Sigma expertise. They train and mentor Black Belts and Green Belts, develop training materials, and serve as technical experts. MBBs typically work full-time on Six Sigma and may oversee multiple projects across the organization.
Black Belt (BB) Black Belts lead Six Sigma projects full-time. They are responsible for project execution using DMAIC methodology, team leadership, data analysis, and delivering measurable results. Black Belts report to Champions and mentor Green Belts.
Green Belt (GB) Green Belts work on Six Sigma projects part-time while maintaining their regular job responsibilities. They support Black Belt projects or lead smaller improvement initiatives within their functional areas. Green Belts apply Six Sigma tools and techniques to solve problems.
Yellow Belt (YB) Yellow Belts have basic awareness of Six Sigma concepts. They participate as team members on projects, contribute subject matter expertise, and support data collection efforts.
Process Owner Process Owners are responsible for maintaining improvements after project completion. They ensure sustainability of gains and have authority over the process being improved.
How the Role Structure Works
The Six Sigma hierarchy functions as a cascading system of expertise and responsibility. Executive Leadership sets strategy and selects high-impact projects. Master Black Belts provide technical guidance and training. Black Belts execute projects with support from Green Belts and Yellow Belts. Process Owners take over once improvements are implemented to ensure long-term success.
This structure ensures proper resource allocation, clear accountability, and knowledge transfer throughout the organization.
Exam Tips: Answering Questions on Six Sigma Roles and Responsibilities
1. Know the Full-Time vs. Part-Time Distinction Black Belts and Master Black Belts typically work on Six Sigma full-time. Green Belts work part-time on projects while performing their regular duties. This distinction frequently appears in exam questions.
2. Understand the Hierarchy of Expertise Master Black Belt > Black Belt > Green Belt > Yellow Belt. Questions often test your knowledge of who mentors whom and who has greater technical expertise.
3. Remember Key Champion Responsibilities Champions select projects, provide resources, remove barriers, and ensure business alignment. They do not perform statistical analysis or lead project teams.
4. Focus on Process Owner Responsibilities Process Owners maintain improvements after project closure. They are accountable for sustaining gains and have authority over the process.
5. Watch for Scenario-Based Questions When given a scenario, identify which role is most appropriate based on the task described. Resource allocation suggests Champion. Statistical training suggests Master Black Belt. Leading a project suggests Black Belt.
6. Remember the DMAIC Connection Black Belts and Green Belts use DMAIC methodology. Champions approve projects during the Define phase. Process Owners become critical during the Control phase.
7. Pay Attention to Keywords Terms like strategic direction, mentoring, training, leading, supporting, and sustaining often indicate specific roles. Match these action words to the appropriate role.
8. Eliminate Wrong Answers First If unsure, eliminate options that assign inappropriate responsibilities to roles. Yellow Belts would not lead projects. Champions would not perform detailed statistical analysis.
