Abstract

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.
