Description
Book SynopsisVital tools for implementing Lean Six Sigma--what they are, how they work, and which to use
The Lean Six Sigma Pocket Toolbook is today's most complete and results-based reference to the tools and concepts needed to understand, implement, and leverage Lean Six Sigma. The only guide that groups tools by purpose and use, this hands-on reference provides:
- Analyses of nearly 100 tools and methodologies--from DMAIC and Pull Systems to Control Charts and Pareto Charts
- Detailed explanations of each tool to help you know how, when, and why to use it for maximum efficacy
- Sections for each tool explaining how to create it, how to interpret what you find, and expert tips
Lean Six Sigma is today's leading technique to maximize production efficiency and maintain control over each step in the managerial process. With The Lean Six Sigma Pocket Toolbook, you'll discover how to propel your organization to new levels of competitive success--one
