Lean Six Sigma
Globalization continues to change the way our customers conduct business and the way we conduct business with our suppliers. Instant access to information, products and services drives a competitive environment that leaves no room for error. We must delight our customers and relentlessly look for new ways to exceed their expectations. This is why Lean Six Sigma has become a part of our culture, not just in language but in execution.
What is Six Sigma?
It is not a secret society, a slogan or a cliche. Six Sigma is a highly disciplined process improvement methodology that helps us focus on developing and delivering near-perfect products and services. "Sigma" is a statistical term that measures how far a given process deviates from perfection. The central idea behind Six Sigma is that if you can measure how many "defects" you have in a process, you can systematically figure out how to eliminate them and get as close to "zero defects" as possible. To achieve Six Sigma Quality, a process must produce no more than 3.4 defects per million opportunities. An "opportunity" is defined as a chance for nonconformance, or not meeting the required specifications.
|Key Concepts of Six Sigma|
|Critical to Quality:||Attributes most important to the customer|
|Defect:||Failing to deliver what the customer wants|
|Process Capability:||What your process can deliver
|Variation:||What the customer sees and feels|
|Stable Operations:||Ensuring consistent, predictable processes to improve what the customer sees and feels|
|Design for Six Sigma:||Designing to meet customer needs and process capability|
What is Lean?
While Six Sigma focuses on minimizing variation resulting in stable and predictable processes, Lean focuses on the elimination of waste. Lean improvements require a deep dive into the effectiveness and efficiency of our processes and that of our supply base.
|Value:||Defined from the customer's view|
|Value Stream:||Identify the process|
|Flow:||Keep it moving, left to right|
|Pull:||From the prior step in the process|
|Perfection:||Always improve the process|
