In this era of stiff competition the economic success of manufacturing firms depends on their ability to identify the needs of customers and to quickly create products that meet these needs and can be produced at low cost. Achieving these goals is not solely a design problem or a manufacturing problem; it is a product development problem involving all of these functions. The present work is carried out in a manufacturing unit, developing industrial products. In its product range the company involves the manufacture of key duplicating machine on small basis and this machine required improvement to survive in competitive market (key making). The paper highlights how the product development techniques are applied in improving the key duplicating machine effectively and efficiently. The present paper discuses about the re-designing and improvements in the product performance. The work was further extended for developing a revised product with better features. The scope of work involves extensive survey of users and design options available. The significant aspect of the present work is that, the theoretical concepts involved in product development have been realized with a practical perspective. The work has been realized by incorporating these improvements in the product. The work is supported by digital prototyping of the model usingCADmodeler.

Key words: Product Development, Performance, re-designing.
