Six Sigma at many organizations simply means a

measure of quality that strives for near perfection.

Six Sigma is a disciplined, data-driven approach and

methodology for eliminating defects (driving toward

six standard deviations between the mean and the

nearest specification limit) in any process – from

manufacturing to transactional and from product to


To Coast to Coast Circuits, Lean Six Sigma means maximizing yields and reliability for everyone of our customer's projects. We identify and eliminate waste and then optimize what is value added by reducing unwanted variation. 

The statistical representation of Six Sigma describes quantitatively how a process is performing. To achieve Six Sigma, a process must not produce more than 3.4 defects per million opportunities. A Six Sigma defect is defined as anything outside of customer specifications. A Six Sigma opportunity is then the total quantity of chances for a defect. 

The fundamental objective of the Six Sigma methodology is the implementation of a measurement-based strategy that focuses on process improvement and variation reduction through the application of Six Sigma improvement projects. This is accomplished through the use of two Six Sigma sub-methodologies: DMAIC and DMADV. The Six Sigma DMAIC process (define, measure, analyze, improve, control) is an improvement system for existing processes falling below specification and looking for incremental improvement. The Six Sigma DMADV process (define, measure, analyze, design, verify) is an improvement system used to develop new processes or products at Six Sigma quality levels. It can also be employed if a current process requires more than just incremental improvement. Both Six Sigma processes are executed by Six Sigma Green Belts and Six Sigma Black Belts, and are overseen by Six Sigma Master Black Belts.

Coast to Coast will preserve and evolve while deploying and maturing a world-class Lean Six Sigma program. Our customer's will directly benefit.
