Dear Chandrasekhar, The concept of sixsigma deployment is not"plug and play" model or simply use JMP or Minitab and get some facinating graphical out puts . Primary requirement is the need for business growth combined with the ownership and commitment for continuous improvement. cost of training and cost of implementation - change management . For any company which has calculated the COPQ and the contribution of poor quality on the customer satisfaction would make them turn towards adopting a methodology to improve the situation and make the organisation survive in the global market. six sigma alone will not help ,it also requires Lean to hasten up the process speed. You will be surprised to know that, many big and small companies donot even know their current process capability , and keep continue blaming the production /service enivronment. If a company makes a holistic approach towards improving the quality of the product by minimising the waste and variance which could be identified and eleminated in each process, then that company will surely adopt Lean six sigma for generating more profit with out investing much on other futile efforts.
