6 SIGMA Can It Work Outside Japan? Dr Adeeb Saify RESPECT ACADEMY palinvest2010@yahoo.com
PPM 6 (Distribution Shifted ± 1.5) Process Capability Defects per Million Opportunities Sigma is a statistical unit of measure which reflects process capability. The sigma scale of measure is perfectly correlated to such characteristics as defects-per-unit, parts-per million defective, and the probability of a failure/error. Operational Excellence Training
Lean Principles Being Fast, Flexible, Economic
Summary • Lean manufacturing was developed by the Japanese. • Lean is a philosophy that seeks to eliminate waste in all aspects of a firm’s production activities. • Lean is principally associated with manufacturing industries but can be also equally applicable to both service and administration processes. • Works on 5 basic principles. • Cornerstone of Lean is the Toyota Production System. • Considers 9 Wastes (muda). • Utilises 5 S methodology.
What is lean? • Lean manufacturing was developed by the Japanese automotive industry, with a lead from Toyota and utilising the Toyota Production System (TPS), following the challenge to re-build the Japanese economy after World War II. • The concept of lean thinking was introduced to the Western world in 1991 by the book “The Machine That Changed the World” written by Womack, Jones, and Roos. • Lean is a philosophy that seeks to eliminate waste in all aspects of a firm’s production activities: human relations, vendor relations, technology, and the management of materials and inventory.
5 principles of Lean • Value - specify what creates value from the customer’s perspective. • Thevalue stream – identify all the steps along the process chain. • Flow - make the value process flow. • Pull - make only what is needed by the customer (short term response to the customer’s rate of demand). • Perfection - strive for perfection by continually attempting to produce exactly what the customer wants.
The Cornerstone of Lean – The Toyota Production System • Based on two philosophies: • 1. Elimination of waste • 2. Respect for people
