Six Sigma basically is a Management philosophy which aims at Customer Satisfaction. If a corporation produces a product or delivers a service which is not up to the Customer’s Satisfaction, then it will have a tough time being Competitive or Profitable for that matter. Reworking on a Product or Service due to inefficient processes means loss of not only Cost of Material, Labour and Time but also of Customers and its Reputation.
It is important to involve the Customer to define what is important to them as, retaining a Customer is as important as gaining a Customer. With appropriate understanding of consumer’s expectation, Corporation should go back and work on their processes to improve the Product or Services on the basis of customers’ requirements. Once these required improvements or changes are identified, and then there should be an objective, numerical approach to evaluate Current Practices as well as its Future Goals. While Six Sigma has many process and steps involved, these are not the only things involved to improve the System it also involves lots of Statistical measurement to do this.
