Lean Banking is one of the first comprehensive works to apply Lean Six Sigma principles to the financial services industry.
Published by Il Sole 24 Ore and prefaced by Mikel J. Harry — the father of Six Sigma — the book provides a rigorous and practical approach to improving efficiency, reducing waste, and enhancing customer value in banks and financial institutions. Drawing on real improvement projects and years of experience across major international banks, the authors demonstrate how Lean methodologies can be adapted to the unique complexities of financial services:
from operational processes, back-office functions, and credit operations, to compliance, risk management, and customer service.
The book offers:
- practical case studies from real banking environments;
- tools and frameworks for analyzing and redesigning processes;
- guidance for executives and managers leading operational excellence programs.
Lean Banking remains a reference text for CEOs, Transformation Leaders, Lean Managers, and professionals seeking to bring scientific rigor and measurable results into the financial sector.
It is not simply a technical manual it is a blueprint for building a culture of excellence inside banks.
