Lean and Six Sigma are buzz-words we hear in business all of the time. Before we get started, let’s make sure we all understand just what we mean by “lean” and “Six Sigma”.

About Six Sigma

Six Sigma is a structured, data-driven process of solving critical issues from a business perspective that we haven’t been able to solve with current methodology.

Six Sigma is the single most effective problem-solving methodology for improving business and organizational performance.

The common measurement scale is called the Sigma capability or Z and is a universal scale. It is a scale like a yardstick measuring inches or a thermometer measuring temperature.

The scale allows us to compare business processes in terms of the capability to stay within the quality limits established for that process.

The Sigma scale measures Defects per Million Opportunities (DPMO). Six Sigma equates to 3.4 defects per million opportunities.

What Six Sigma is and is not:

About Lean

“Lean” means continuously improving towards the ideal and achieving the shortest possible cycle time through the tireless reduction of waste.

History Behind Lean

The phrase “lean manufacturing” was coined in the 1980’s and has its roots in the Toyota Production System. (See later in this module)

Most of the basic goals of lean manufacturing are common sense, and some fundamental thoughts have been traced back to the writings of Benjamin Franklin.

Henry Ford cited Franklin as a major influence on his lean business practices, which included Just-in-time manufacturing. The founders of Toyota designed a process with inspiration from Henry Ford and their visits to the United States to observe the assembly line and mass production that had made Ford rich. The process is called the Toyota Production System and is the fundamental principle of lean manufacturing.

Two books have since shaped the ideologies of Lean: “The machine that changed the world” (1990) and “Lean Thinking” (1996).

Toyota Production Systems

The Toyota Production System (TPS) is a mindset and management system that embraces continuous improvement. TPS organizes manufacturing and logistics, including interaction with suppliers and customers. Originally called “Just in Time Production,” it builds on the approach created by the founders of Toyota. TPS revolves around 5 simple steps:

The Toyota Precepts

The five methods defined by Toyota contain some basic principles:

CHALLENGE: Form a long-term vision, meeting challenge with courage and creativity to realize your dreams.

KAIZEN: Improve your business operations continuously, always driving for innovation and evolution.

GENCHI GENBUTSU (Go and see): Go to the source to find the facts to make correct decisions, build consensus, and achieve goals at our best speed.

RESPECT: Respect others, make every effort to understand each other, take responsibility and do your best to build mutual trust.

TEAMWORK: Stimulate personal and professional growth, share the opportunities of development, and maximize individual and team performance.
