Lean Six Sigma: Simplified - How to Implement The Six Sigma Methodology to Improve Quality and Speed (Lean Guides with Scrum, Sprint, Kanban, DSDM, XP & Crystal)

Inside:

- The principles, in their original form, before consultants softened them.
- The practices that produce the results everyone wants from these methods.
- When Lean is the wrong answer. Honest cases where waterfall is faster.
- How to introduce these frameworks to teams that have heard the buzzwords too many times.
- The cultural and organizational patterns that determine success or theater.
- Real-world examples - both wins and the kind of failures that get hidden in case studies.

Read this if you're tired of doing the rituals without the results.

Greg Caldwell writes for entrepreneurs, founders, and team leads who want to build faster, smarter, and leaner. His books break down the methodologies that drive modern business - Lean Startup, Agile, Scrum, Kaizen, and Lean Analytics - into clear, implementable frameworks anyone can apply, whether you're launching a startup or scaling a team.

Greg's style is practical and outcome-driven: less theory, more execution. Each book gives readers the tools and mental models they need to ship better products and run leaner operations.
