The alternative of the implementation of 6 sigma is the enhancement of the quality level of the firm to such degree as 6 sigma level based upon the current level which reflects customers satisfaction of products or services Many firms are trying to implement 6 sigma by a project basis which, sometimes results to inconsistency with the managerial objectives of the firm. Under the such circumstances, the successful implementation of 6 sigma depends on the features of the project selected. This paper proposes a model to the efficient project selection based on Total Productivity. This method is an alternative to the CTQ(critical to quality), which has been found sometimes to be inconsistent to managerial objective. This paper constructs a process model for project selection, finding out strategies which are consistent to managerial objectives, and a process of the establishment of strategy to 6 sigma planning. Finally, this paper shows the application of the new model to a firm and test its validity, and finds that 71 method is more efficient than CTQ method.
