Improving Quality with Six Sigma

What is Six Sigma?

Six Sigma is a rigorous and structured management approach that aims at developing and delivering near-perfect products and services. 

Initially set as a manufacturing goal towards zero defect, over time, Six Sigma has evolved into a management philosophy as more service industries adopt the approach.  Today, it is widely adopted as a management system and business strategy.

Sigma is a statistical term that represents how far a given process deviates from perfection. It is used as a measure of process capability. The core idea behind Six Sigma is that if we can measure the "defects" in a process, we can adopt a systematic approach to eliminate them and get as close to "zero defects" as possible.

When a process operates at a Six Sigma level, the deviation is so small that the resulting products and services are 99.9997% defect free or no more than 3.4 defects per million opportunities (DPMO).  An "opportunity" is defined as a chance for non-conformance, or not meeting the required specifications.  This means we need to be nearly flawless in executing our key business processes.

While Six Sigma corresponds to being 99.9997% defect free, not all business processes need to attain this level of performance.  Organizations can also use the Six Sigma approach to identify top opportunities with the highest value and then focus their improvement efforts there. ​

 

The DMAIC Approach to Process Improvement

All your existing business and supporting processes can be improved using the Six Sigma DMAIC approach. The five phases of the DMAIC methodology are commonly used in process improvement.  The phase objectives are described below.

DEFINE

Define the problem or opportunity.

MEASURE

Measure the current performance or capability.

ANALYZE

Analyze to identify root causes.

IMPROVE

Improve by implementing potential solutions.

 CONTROL 

Control by standardizing solutions and monitoring performance.

Learn how to implement Six Sigma as a rigorous and structured approach to help your organization improve its performance in meeting customer requirements.  

Benefits of Six Sigma

One of the distinguishing features of Six Sigma from other approaches is a clear focus on achieving bottom-line results within a relatively short period of time.

The benefits of Six Sigma are many.  They include the following:​
 

  •     Defining a measurable way to track performance improvements

  •     Focusing our attention on process management at all levels of the organization

  •     Improving customer relationships by addressing “defects”

  •     Improving the efficiency and effectiveness of processes by aligning them with customers’ needs

​After seeing the huge financial successes at Motorola, GE, Bank of America and other early adopters of Six Sigma management, many organizations world-wide have now instituted Six Sigma management programs.

 

The Six Sigma management approach can be applied to both manufacturing and service industries.
