(OPI), is all about reduce costs and continue to improve
performance and improve the bottom line (profit %).
A systematic approach to help an organization optimize
its underlying processes to achieve more efficient results.
Reduce variation and/or waste in processes, so that the
desired outcome can be achieved with better utilization of
resources.

10. Six Sigma methodology for OPI
• A business management strategy, originally developed by Motorola,
USA in 1986.
• Seeks to improve the quality of process outputs by identifying and
removing the causes of defects (errors) and minimizing variability in
manufacturing and business processes.
• Uses a set of quality management methods, including statistical
methods, and creates a special infrastructure of people within the
organization ("Black Belts", "Green Belts", etc.) who are experts in
these methods.
• Each Six Sigma project carried out within an organization follows a
defined sequence of steps and has quantified financial targets (cost
reduction and/or profit increase).
