Six Sigma is a rigorous and disciplined methodology that uses data and statistical analysis to measure and improve a company's operational performance by identifying and eliminating "defects" in manufacturing and service-related processes. Commonly defined as 3.4 defects per million opportunities, Six Sigma can be defined and understood at three distinct levels: metric, methodology and philosophy.
The Six Sigma Strategy
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. This means we need to be nearly flawless in executing our key processes. Clients value consistent, predictable business processes that deliver world-class levels of quality. This is what MAC strives to produce through our Six Sigma process improvements.
Critical to Quality:
Attributes most important to the customer
Failing to deliver what the customer wants
What our process can deliver
What the customer sees and feels
Ensuring consistent, predictable processes to improve what the customer sees and feels
