You Can't Manage What You Don't Measure!

Frequently Asked Questions

Q:What is Five S?
A: 5-S was initially made famous by the Toyota Corporation. The late Dr. Shigeo Shingo was the main promoter of this concept within TPS (Toyota Production Systems). By starting with the premise that quality often circles back to lack of organization and neatness, it is not such a difficult transition to believing that opportunity in lean materials management lies also in the 5-S concepts.

Q: What is Six Sigma?
A:Six Sigma is a business management strategy originally developed by Motorola, USA in 1986. As of 2010, it is widely used in many sectors of industry, although its use is not without controversy.

Six Sigma seeks to improve the quality of process outputs by identifying and removing the causes of defects (errors) and minimizing variability in manufacturing and business processes. It uses a set of quality management methods, including statistical methods, and creates a special infrastructure of people within the organization ("Black Belts", "Green Belts", etc.) who are experts in these methods. Each Six Sigma project carried out within an organization follows a defined sequence of steps and has quantified financial targets (cost reduction or profit increase).

The term Six Sigma originated from terminology associated with manufacturing, specifically terms associated with statistical modeling of manufacturing processes. The maturity of a manufacturing process can be described by a sigma rating indicating its yield, or the percentage of defect-free products it creates. A six sigma process is one in which 99.99966% of the products manufactured are statistically expected to be free of defects (3.4 defects per million). Motorola set a goal of "six sigma" for all of its manufacturing operations, and this goal became a byword for the management and engineering practices used to achieve it.

Like its predecessors, Six Sigma doctrine asserts that:
◦Continuous efforts to achieve stable and predictable process results (i.e., reduce process variation) are of vital importance to business success.
◦Manufacturing and business processes have characteristics that can be measured, analyzed, improved and controlled.
◦Achieving sustained quality improvement requires commitment from the entire organization, particularly from top-level management.

Features that set Six Sigma apart from previous quality improvement initiatives include:
◦A clear focus on achieving measurable and quantifiable financial returns from any Six Sigma project.
◦An increased emphasis on strong and passionate management leadership and support.
◦A special infrastructure of "Champions," "Master Black Belts," "Black Belts," "Green Belts", etc. to lead and implement the Six Sigma approach.
◦A clear commitment to making decisions on the basis of verifiable data, rather than assumptions and guesswork.

Q: What is Lean Production?
A: Lean manufacturing or lean production, often simply, "Lean," is a production practice that considers the expenditure of resources for any goal other than the creation of value for the end customer to be wasteful, and thus a target for elimination. Working from the perspective of the customer who consumes a product or service, "value" is defined as any action or process that a customer would be willing to pay for. Basically, lean is centered on preserving value with less work. Lean manufacturing is a generic process management philosophy derived mostly from the Toyota Production System (TPS) (hence the term Toyotism is also prevalent) and identified as "Lean" only in the 1990s. It is renowned for its focus on reduction of the original Toyota seven wastes to improve overall customer value, but there are varying perspectives on how this is best achieved. The steady growth of Toyota, from a small company to the world's largest automaker, has focused attention on how it has achieved this.

Q: What can I do to start a safety program in my shop?
