Six Sigma – Quality and Process Improvement

​

Approach

​

Six Sigma is an effective and adaptable measurement-based improvement methodology which can be used for delivering quality IT services. The main aim of Six Sigma is to reduce variation in processes by offering a structure by which organisations can constantly improve routine IT processes and eliminate defects, waste and cost, thereby increasing service quality and customer satisfaction.

​

Six Sigma can be used in conjunction with the ITIL (Information Technology Infrastructure Library) framework.

​

There is no formal certification for an organisation against the Six Sigma framework. However, one of the main parts of Six Sigma implementation is the need to train certain individuals to a high degree of familiarity with the methodology itself so that they can work on the implementation/project team.

​

Various levels of qualification are available for these individuals to demonstrate their level of competence in Six Sigma. Black Belt, for example, certifies the individual is a highly experienced Six Sigma practitioner; Green Belt demonstrates that an individual has trained in Six Sigma and is qualified to work on the implementation/project team under the direction of a Six Sigma Black Belt.
