Abstract
In today's world of globalization and competitive environment, small scale industries have to develop economically sustainable plan which can provide them competitive edge. In this scenario customer satisfaction is replaced by customer delight by providing those products of their requirements at reduced cost. To attract the customers and making more profit a company must concentrate on quality of its product. Quality of the product depends on the reduced variation in the process during production. So if the process is under control than the quality of the product will be good but if it is out of control than it results in rework, rejection, scrap etc. which is indication of poor quality. So to reduce the variation in process the statistical process control techniques are used. This paper presents a case study of implementation of statistical process control (SPC) techniques for reduction of rework cost in a transformer radiator manufacturing small scale industry which is located in Vadodara, Gujarat, India.With the help of different tools and techniques such as 7 basic quality control tools, cost of quality etc. the rework cost of the radiator are reduced with improvement in quality and productivity.
