Often we have heard that the work lacks quality and the project is resulting in high cost. So is there any method by which the quality can be improved and cost can be reduced? The answer is YES, the method is six sigma methodologies. Six sigma is a management philosophy that was developed to reduce costs, increase profits and reduce wastage of an organization. The method was developed by MOTOROLA in 1986. It had been made as central business strategy for General Electric in 1995. This method was developed to improve the quality, establish a world class standard and save the cost for the company. As the costs are reduced the revenues generated increase thus creating a profitable situation for the organisation.
