As a consequence of economic reforms, the Indian manufacturing sector faces a variety of technology related challenges. It not only has to quickly develop world-class manufacturing capabilities but also gear up to develop new products and process. In this paper we analyse the technology strategies of six Indian firms in different products groups which are trying to build competitive manufacturing & technology capabilities. The linkages between corporate, technology, and manufacturing strategies are explored and the role of complementary assets is studies in order to identify patterns through which these firms are building capabilities of various kinds. Specifically, we evaluate the extent to which firms use supply chains to develop product & process technologies.
