In the present state of affairs, data is collected and analyzed for any change. Data is, in fact, experience is stored. This data with statistical analysis gives results about performance of a process. The main attempt of the top management is to decide on the benchmark for improvement and to devise a methodology for change in work ethics and process improvement. This is done by what is called ‘six-sigma’, which is about precision and accuracy leading to data driven strategy and decisions. The current practice of six sigma is an extension of the previous work of Brandy and Allen [2].
The paper outlines the basic essentials of six-sigma theory, its main characteristics and the powerful methodology (DMAIC) consisting of 5 steps: Define, Measuring, Analyze, Improvement and Control. Interestingly, Mumbai’s ‘Dabbawala’ case study is a case of six-sigma rating.
