Lean Six Sigma Master Black Belt: Governing Programmes and Developing Practitioners takes Lean Six Sigma beyond individual improvement projects and into the leadership, governance and capability required to make improvement work across an organisation.

Written for experienced practitioners, operational leaders and those progressing towards Master Black Belt-level responsibility, Robert Porter connects analytical discipline with the realities of leading complex, cross-functional change.

The book explores how Master Black Belts select and govern improvement portfolios, establish effective DMAIC governance, challenge evidence, develop measurement systems and ensure that analytical methods support real operational decisions rather than becoming exercises in statistics.

Readers are introduced to capability analysis, hypothesis testing, regression, designed experiments, statistical process control, benefits assurance and analytical governance alongside the equally important disciplines of leadership, coaching, assessment and organisational capability building.

The guide also examines strategy deployment, practitioner development, project selection, cross-functional governance, maturity and the ethical responsibilities that accompany senior improvement leadership.

Practical operational examples demonstrate how these principles translate into real environments where people, systems, risk, customers and competing priorities interact.

Rather than treating the Master Black Belt as simply the highest technical belt, this book presents the role as one of organisational stewardship: developing practitioners, challenging assumptions, protecting the integrity of evidence and creating an improvement system capable of sustaining itself.

Practical experience. Clear thinking. Better work.
