Six Sigma seeks to improve the quality of process outputs by identifying and removing the causes of defects, errors, failures, and minimizing variability in service, transactional, manufacturing and other business processes. It 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.). Each Six Sigma project carried out within an organization follows a defined sequence of steps namely Define, Measure, Analyse, Improve and Control (DMAIC) and has quantified financial targets (cost reduction or profit increase).
The maturity of an existing or new process can be described by a sigma rating indicating the percentage of defect-free products or successes it creates. A six sigma process assures 99.99966% of the products manufactured or services rendered are statistically free of defects (3.4 defects per million).
Six Sigma is being coveted by manufacturing & services industries including Motorola, GE, BOAMerrill Lynch, AXA, HSBC Group, Credit Suisse, Samsung, Mc-GrawHill, Starwood Hotels, PepsiCo, Toshiba and other diverse corporate powerhouses. Individuals trained in PMP, CAPM, ITIL, ISO, CMMI and other Technical/Professional Courses can add Six Sigma certification for better career growth, as Six Sigma certification best fits into continuous improvement approaches. |
