  • The Telecommunication Industry: Cisco and Lucent's Supply Chains
    The Telecommunication Industry: Cisco and Lucent’s Supply Chains by Yishai Boasson M.Eng. Massachusetts Institute of Technology © 2005 Yishai Boasson All rights reserved The author hereby grants to MIT permission to reproduce and to distribute publicly paper and electronic copies of this thesis document in whole or in part. The Telecommunications Industry: Cisco and Lucent’s Supply Chains by Yishai Boasson Abstract This work aims at describing the current trends in supply chain management prevalent in the telecommunications industry. This is done through looking at the telecommunications industry (telephony and data communications), its history and the factors shaping what it currently is. In addition, two companies – Cisco Systems Inc. and Lucent Technologies Inc. are used as two case studies. Looking at these two companies enables us to dive deeper into actual supply chain practices, trying to understand current best practices. As we analyzed these two companies’ supply chains, we used a framework delineated by the belief that excellent supply chain management is a collection of business processes supporting operational goals, which in turn should enable an overall business strategy. Our initial perception of current supply chain practices was shaped by available literature as well as by the image projected by telecommunications companies in forums and publications concerning their supply chain management practices. However, the opportunity to look closely and intimately at one of Cisco’s supply chains has revealed a slightly different picture, where supply chains are not necessarily used as a means to gain sustained competitive advantage. In addition, marked differences in the two companies’ 2 practices might be attributed not only to differing strategies, but also do differing histories.
