Information technology (IT) organizations increasingly are under pressure to improve their service and process capability. In the quest for improvement methodologies, organizations often adopt a “pick one” strategy – with Six Sigma being the widely favored choice. However, it is possible to integrate Lean and Six Sigma and reap the full benefits that these methodologies can bring to the table.
Defined as a measure of quality that strives for near perfection, six sigma is a disciplined, data-driven approach and methodology for eliminating defects (driving towards six standard deviations between the mean and the nearest specification limit) in any process -- from manufacturing to transactional and from product to service. To achieve six sigma, a process must not produce more than 3.4 defects per million opportunities.
