Introduction
In the Lean Six Sigma world, different certification levels represent increasing expertise and leadership. While a Black Belt leads improvement projects, a Lean Six Sigma Master Black Belt (MBB) leads entire programs and builds internal capability.
They are the architects of transformation—driving enterprise-wide improvement, mentoring others, and embedding Lean Six Sigma into the company’s DNA. If Jv’s Pizza expanded nationwide, the MBB ensures every branch follows a consistent and effective improvement strategy.
To explore Lean Six Sigma training options for every level—including Master Black Belt—visit Lean 6 Sigma Hub, your trusted platform for expert-led certification.
What is a Lean Six Sigma Master Black Belt?
A Lean Six Sigma Master Black Belt is a strategic coach, deployment leader, and systems thinker. They don’t just lead projects—they lead people who lead projects, and they design the systems that make improvement sustainable.
Their core responsibilities include:
- Coaching Black Belts and Green Belts
- Leading cross-functional improvement programs
- Designing and governing Lean Six Sigma rollouts
- Ensuring alignment with business strategy
- Measuring ROI and capability maturity
MBBs operate at a strategic level, often working closely with executives, sponsors, and operational leaders.
How is a Master Black Belt Different from a Black Belt?
| Area | Black Belt | Master Black Belt |
|---|---|---|
| Scope | Project-level or departmental | Enterprise-level and cross-functional |
| Focus | Problem-solving and execution | Coaching, strategy, deployment leadership |
| Tools | DMAIC, Lean tools, data analysis | Governance models, coaching systems, enterprise diagnostics |
| Influence | Operational teams | Executive leadership and culture |
| Outcome | Project success | System sustainability and capability building |
Black Belts execute change. Master Black Belts institutionalize it.
What Does a Master Black Belt Actually Do?
A certified MBB typically performs a combination of the following:
1. Coaching & Mentoring
MBBs support and guide Black Belts and Green Belts through all stages of DMAIC, providing review checkpoints and technical support.
2. Strategic Program Leadership
They help define which projects align with business priorities and ensure consistency in execution across the enterprise.
3. Governance & Oversight
They design review boards, project tollgate systems, and performance dashboards to measure impact across all initiatives.
4. Executive Communication
MBBs bridge the gap between improvement teams and leadership, translating project results into strategic language.
5. Capability Building
They are responsible for rolling out Lean Six Sigma training programs and building internal certification pipelines.

- Implement a shared data dashboard
- Train regional managers as certified Green Belts
