7Epsilon Background and Vision

In 2010, a European call for proposals bought together a consortium of foundries and premier academic institutions together. The objective was to overcome limitations of Six Sigma techniques so that the foundry industry moves towards the zero defects manufacturing environment.

  • The 7Epsilon word was coined by Dr. Patricia Caballero at Tecnalia, Spain to signify a European approach for introducing a culture of innovation ’ within foundries. The research team, led by Dr Rajesh Ransing at Swansea University, has developed the 7Epsilon concept with a goal of realising in-process quality improvement and introduced 7 steps to ERADICATE defects.
  • For mathematicians an epsilon is a small positive quantity, whereas for economists it measures the responsiveness of a function to changes in parameters. It quantifies error for statisticians i.e. calculates deviation of the modelled value from its true value.
  • In the proposed Zero Defect Manufacturing approach, an Epsilon is a positive step that is responsive to changes in business and manufacturing process parameters. Zero defect manufacturing requires a cultural and step change in the thought process, across the industry.
  • 7Epsilon concept was launched in 2012 via series of road shows, YouTube videos and courses .
  • The 7Epsilon approach of data visualisation using penalty matrix approach has inspired formation of a start-up company p-matrix Ltd that developed a software tool for the data visualisation and is now co-ordinating 7Epsilon case studies and courses across the world.
  • The 7Epsilon philosophy integrates ISO9001:2015's requirements on risk based thinking and organisational knowledge to provide a pathway for in-process quality improvement overcoming the limitations of Six Sigma.
