What is Six Sigma?

Six Sigma is the continuous pursuit and reduction of waste and defects, utilising statistics and other tools and techniques to identify opportunities, implement and measure improvement and maintain control of the process.

What is the literal meaning of Six Sigma?

Six Sigma is a statistical measure of performance of anything you care to analyse.

Sigma (σ) is statistical shorthand for a standard deviation.

A standard deviation is a statistical way to describe how much variation exists in a set of data or a group of items – a process. For example if you look at the length of time it takes to clear all invoices the standard deviation will be higher than if you only looked at invoices from one supplier. To take this example a stage further, look at this table:

Six Sigma
% of invoices cleared on time Sigma Defective invoices per million
30.85 1 691500
69.15 2 308500
93.32 2 66800
93.32 3 66800
99.38 4 6200
99.977 5 230
99.99966 6 3.4

Six Sigma is a tool that leads to

  • genuine focus on the customer
  • improved quality and lower costs
  • data and fact driven management
  • processes governing the systems
  • proactive management
  • a company with fewer boundaries
  • a drive for perfection by addressing failure
