Six-Sigma Implementation


What is Six-Sigma?

Six-sigma is a statistical term that refers to the standard deviation of a process about its mean.

In a normally distributed process, 99.73% of measurements will fall within +/- 3.0 sigma, and 99.99966% will fall within +/- 4.5 sigma. A process with a normal distribution and normal variation of the mean, would need to have a specification limits of +/- 6.0 sigma in order to produce less than 3.4 defects per million opportunities – this is Six-Sigma.

The roots of Six Sigma as a measurement standard can be traced back to Carl Frederick Gauss, who introduced the concept of the normal curve. Six-Sigma, as a Total Quality Management (TQM) implementation is a concept that originated in Motorola. Bill Smith, of Motorola, is considered as the “Father of Six Sigma” movement.

In 1986 Bill Smith introduced the concept of Six Sigma to standardize the way defects are counted. In Smith’s words, “We recognized that the issue was not building a single part with one characteristic, it was building a product with thousands of parts. If you reduce the total defects, you increase customer satisfaction and reduce costs.”

When operations reach Six-Sigma quality, defects becomes so rare that when they do occur, they get into limelight and thus receive full attention necessary to determine and correct the root-causes.

Six-Sigma implementation is a process generally defined by its acronym “DMAIC”, viz.:

Define: Select the appropriate variables to be improved;

Measure: Collect data to measure the response variables;

Analyze: Identify the root-causes of defects;

Improve: Reduce or eliminate variability;

Control: Monitor the process to sustain improvements.

What do we offer in Six-Sigma Implementation?

At Rao Strategic Solutions, we have adopted the standards proposed by the American Society for Quality, ASQ. As ASQ, suggests, the two implementation options are:

  1. Implementing a Six-Sigma program
  2. Creating a Six-Sigma Infrastructure.

Each company and each situation requires a unique solution. we do not prescribe “cookie-cutter” solutions. Our team of experts will help you to assess your organization in light of your goals and mission in order to identify, analyze and reengineer the core business processes of your venture in an effort to reduce costs and maximize efficiency.
