Competitive pressures, industrial or societal innovations, and government regulations are some of the many factors that drive the need for new or better products. Companies respond to these drivers and changing needs by developing new products and employing product development processes (PDPs) to coherently manage the risks inherent in their development. Well-designed PDPs reduce development time, create better products, generate profit, and increase market share. In contrast, poorly-designed PDPs can severely harm both product lines and the companies that manufacture them. Many companies seek guidance in making important PDP design decisions. This thesis introduces PDPs as risk management frameworks. The research investigates the relationship between PDPs and risk management and seeks to help companies improve PDP design. It begins by discussing the drivers and risks of product development and then describes different PDPs. The traditional stage gate process is compared with the modified waterfall process, evolutionary prototyping, evolutionary delivery, design to schedule/budget process, the spiral process, and several other PDP variations. The research then proposes several iteration- and review-based metrics by which PDPs can be more effectively identified and compared. Ten company case studies exemplify a wide variety of actual PDPs, demonstrate the utility of iteration and review metrics in distinguishing PDPs, and illustrate how different processes manage different risks. Case study findings indicate that software development companies face rapidly-changing markets, generally perform quick integrations and tests, and are likely to employ flexible PDPs. / (cont.) In contrast, manufacturing companies that face greater integration difficulties and technical risks are likely to employ more rigid PDPs. Integration and risk are both instrumental in determining the applicability of different PDPs. The research employs case study lessons to propose a method for improved PDP design based on risk and integration. To demonstrate the method, it is applied to one company. The thesis concludes that PDPs vary more than previously documented; that the proposed metrics are useful in distinguishing PDPs, their different integrations, and their different risk management methods; and that companies facing different risks can more thoughtfully tailor their PDP designs to suit their own unique circumstances. / by Darian W.

In Brazil, scientists from different disciplines are reengineering sugarcane-a crop central to the colonial project-at molecular, organismic, and economic scales in order to expand biofuels as international energy commodities. I argue that biology has become central to what I call the plantation network: a postcolonial agricultural formation that includes laboratories as obligatory passage points in the growing of plants to meet human needs and desires, especially in the era of "sustainability" and "green capitalism." My research uses the plantation network formation to show that even though Brazilian scientists work under ethical and ecological threats posed by climate change, they also rely on Brazilian history, ideology, and cultural practices as they reshape life forms, landscapes, and labor in Brazil and Mozambique. This multisited analysis draws on ethnographic research conducted with molecular biologists attempting to create the world's first commercially viable transgenic sugarcane plant, biochemists working to develop waste-reducing fermentation technologies by using bioprospected "wild" yeasts to digest sugarcane bagasse, and a think tank of agronomic economists seeking to transfer a "Brazilian biofuel model" to Lusophone Mozambique. For these scientists, Brazil's long history of sugarcane is coming to center on ethoses and practices of what they call "sustentabilidade" (sustainability): a form of technoscientifically-aided industrial development that contributes to environmental wellbeing while maintaining the possibility of continued capitalist production for future populations. The dissertation examines "sustainability" as it has emerged in these sites by considering the plantation as a pharmakon-like entity: at the same time (1) a destructive nexus of social-ecological relations that has propelled the harmful, unjust conditions that have led to calls for "sustainable" practices and principles and (2) a redemptive space for ethically-sound renewable fuel and food production that scientists believe is central to creating a more just, livable world. I investigate how scientific practices related to ethically-rendered biofuels are motivating changes to the biotechnologies, production techniques, and locations of sugarcane plantations. / by Nicole Francesca Hayes Labruto. / Ph.

It is more the case for some pollutants than for others, but, in any case, policies tackling the emissions of these sectors have been very few, and of very limited effect. Even the measurement of the emissions is believed to be underestimated, especially for the informal sector, which is mostly unaccounted for in the recent emissions inventories developed in the MCMA. This thesis intends to improve the estimation of commercial and informal emissions in MCMA, through a qualitative assessment of the range of emission sources in these sectors, and an emissions model based on the integrated scenario analysis methodology implemented in the Mexico City Program at MIT. The ultimate goal of this research is to propose and evaluate new policies to reduce commercial emissions, both formal and informal, in MCMA. / by Andres Flores Montalvo. / S.M.

This problem is commonly known as the "spam problem." Solutions to the spam problem involve curbing the adverse affects of existing technology as well as steering technology development in a socially beneficial direction. Unlike some other technology and policy problems, the reasons for the existence of this problem are well known and the desired effects of ideal solutions can be readily articulated. However, attempted solutions to date have not made much progress at solving the problem. I posit that this failure stems from the fact the spam problem is really a complex system, and that solutions to date have not been designed to interact with this system in a useful manner. I show that the spam problem is a complex system, and should be dealt with by developing strategies to holistically interact with it. Such strategies must embrace both technical and legal realities simultaneously in order to be successful. They must also avoid causing negative side effects that negate their purpose. First, I build a model of the system surrounding the spam problem in the form of a Causal Loop Diagram. This diagram shows the causal interactions between the various technical, legal, social, and economic forces that are present in the spam system. Using this diagram, I then identify a number of places that solutions could interact with this system. These places comprise a set of possible levers that could be pulled to alleviate the spam problem. This set of levers is then used to make sense of the attempted and suggested solutions to date. / (cont.) Various solutions are grouped by how they interact with the system. These solution categories are then presented in detail by showing, diagrammatically, how they positively and negatively affect the spam system through their interactions with it. In so doing, I attempt to argue persuasively that much of the current energy expended toward the spam problem is largely unnecessary, and in some cases, counterproductive. I additionally argue that because of the current reality of the spam problem, i.e. particular facts, we are already in a decent position to largely solve this problem by just redirecting current efforts toward more appropriate activity. Such appropriate activity is suggested, which includes steps to increase the identifiability of email in order to enable more successful litigation. Finally, an optimistic conclusion is reached that there are no fundamental reasons why the spam problem can not be dealt with in such a manner to ensure the continued usefulness of email as a communication medium. / by Gabriel R.

It argues that early-to-mid twentieth century naval officers' development and employment of increasingly sophisticated shipboard command and control systems fundamentally altered the human experience of warfare at sea. Based predominately on archival research, Managing a Sea of Information follows a narrative format. It begins by examining the United States Navy's adoption of radio and challenges the notion that a conservative officer corps failed to appreciate the potential advantages of this new communications technology. The bulk of the study explores the Navy' s development of shipboard command and control systems from World War I through the beginning of World War II, focusing particularly on the efforts of operational commanders to maximize their capabilities through the adoption of devices, methods, and procedures for the collection, processing, and dissemination of information. These efforts gradually changed the nature of command at sea, from an environment in which commanders could make informed tactical decisions with relatively limited input from subordinates, to one characterized by epistemic actions and socially-distributed cognition. The dissertation concludes with a brief analysis of shipboard command and control systems during the Second World War, concentrating especially on the United States Navy's creation of the Combat Information Center (CIC). / by Timothy Scott Wolters. / Ph.D.

Every player needs an efficient strategy for achieving C()St effectiveness of processes and quick commercialization of innovations. In order to identify solution to these problems, this thesis focuses on technology strategies in data networking industry acquisitions. This thesis follows the acquisition efforts in recent years of two technology industry giants: Cisco Systems and Lucent Technologies. It probes the companies' motivations and rationale behind their acquisitions, the impact upon the firms' portfolio of technological competencies, and potential and actual penetration of new markets and access to new technologies as a result of the acquisitions. In addition, organizational issues posed by technology management and other subsequent effects on their core competencies are discussed. Comparative analyses of these companies led to key considerations of success/failure factors in acquisition and development (A&D) activities related to firm selection, integration, and evaluation processes. Effective formulas for A&D are summarized as they relate to critical strategic assets such as market, product, technology, value chain, IT, location, organization, people, culture, and vision. As a result of this study, the thesis produces guidelines for the technology strategy of Nippon Telegraph and Telephone Corporation (NTT). The Japanese telecom industry is currently exposed to more severe competition than ever before due to the partial breakup of NTT in July 1999. The guidelines focus on the importance of recognizing both the A&D execution model and the feasibility of the recommended formulas and execution of consistent technology strategies based on past internal/external know-how and experiences. / by Kazuhiko Ohkubo. / S.M.M.O.T.

This dissertation considers contemporary influenza policy as a case study in what I call medical politics, in which a disease that for most people is rather unremarkable has become the focus of intense (and costly) public health campaigns based on a shaky scientific basis. The dissertation seeks to explain how this could happen. The first two chapters show how influenza and its pandemics are marketed through an appeal to numerous scientific claims. Drawing on governmental marketing materials, statements by officials, and policy documents, I try to let officials speak for themselves and, as much as possible, refrain from analysis. Chapter 3 tells the story of the 2009 novel influenza H1N1 outbreak, showing how official understandings about influenza were called into question by an outbreak far milder than experts had predicted, and discusses investigations which highlighted the role of industry in shaping influenza policy. Chapter 4 analyzes official scientific claims regarding influenza, and argues that degree to which influenza is a serious public health problem is actually unclear. Furthermore, influenza vaccine effectiveness has been vastly overstated, predictive models of pandemic influenza are demonstrably flawed, and officials conflate true influenza with influenza-like illness (ILl), an often overlooked but critical distinction which allows officials to mislead the public into holding false assumptions about the potential benefits of influenza vaccine. Chapter 5 highlights the centrality of "virus-centric thinking" and the ethic of "saving lives" in public health practice as important factors that help explain how such a situation can exist and persist in light of the evidence. Chapter 6 addresses the policy implications of the dissertation's findings. / by Peter N. Doshi. / Ph.D.in History, Anthropology, and Science, Technology and Society (HASTS

Thesis (S.M.M.O.T.)--Massachusetts Institute of Technology, Sloan School of Management, Management of Technology Program, 2000. / Includes bibliographical references (leaves 103-105). / Recently Japanese oil companies have been struggling to provide customers with differentiated services and satisfaction, and to capture their perception. They tried changing the relationship with dealers over multiple distribution channels in order to solve this issue. Through trials and errors the oil companies managed to have dealers under their control by vertical integration, but the vertical integration did not result in positive impact for either the oil companies or the dealers since lack of communication brought about conflict between them regarding marketing approach. By learning from practice oil companies have been changing their channel control policy from vertical integration to partnerships that enable the oil companies and their dealers to create more intimate and consequently cooperative relationships. Furthermore, their challenge to channel management has resulted in developing new distribution channels by building partnerships with unrelated industries. This thesis focuses on the dynamics of two partnership models in the distribution channel, vertical partnerships, a new type of relationship between suppliers and their dealers, and horizontal partnerships that are strategic distribution alliances with unrelated industries. First, the driving forces of these partnerships are presented and from that hypotheses are built that determine successful relationships with partners and positive impact for customers. Following that is research and analysis of partnership cases from Japanese oil companies that verify these hypotheses. Further, key factors are extracted from the cases and their validity is checked by adapting each hypothesis. Finally, key factors are prioritized by using an attribution map and the conclusion is a successful methodology for vertical and horizontal partnerships specific to Japanese oil companies. / by Hirotaka Yamanami. / S.M.M.O.T.
