Carmakers and suppliers must work aggressively to improve their warranty management approach as warranty cost often equals or exceeds their investment in engineering. This thesis focuses on studying warranty management in a supply chain from a systems perspective. Warranty data in the automotive industry, focused upon a "Tier one" supplier, is analyzed to obtain general warranty trends and typical failure types. Following the data analysis and hypothesis formation, a sequential series of surveys and interviews within the supplier are conducted in attempt to determine the root causes of warranty failures. A major finding of the study is the lack of a cross-company and long-term approach for dealing with warranty. Other root causes (though not as deeply imbedded as that noted first) include the lack of design discipline, design knowledge, and resources in the product development process. In addition, unclear accountability, poor communication, and lack of a supplier management process delay the warranty resolution process. Furthermore, the culture and mindset in an organization is a critical element in effective warranty management. A reactive warranty firefighting mindset is inadequate to attack the significant warranty issues. Based upon solving the root causes found in the research, the thesis provides five specific recommendations. These recommendations appear likely to be useful to a wide variety of automotive companies as well as manufacturers in other industries.

The methodology used is the application of the Scope and Solution Neutrality principle to develop a general model for Project Systems using the Object- Process-Method (OPM) for systems modeling. By correlating the elements and attributes that constitute basic project artifacts with process performance enablers, a Systems Approach to Performance Improvements is developed. Systemic factors that affect a project's performance, and its ability to address issues, are identified using the Project System model, and project failure modes as well with their underlying causes are examined. The Systems Approach to Process Improvements is then applied to addressing these issues. A key insight gained from the modeling is the importance of communication and information flow as a critical function for effective project management and execution. Consequently the impact of optimizing information flow on project execution is demonstrated through systems dynamics modeling.

S. (Amarnath Sury) The mobile services ecosystem has evolved and continues to evolve at a rapid pace adjusting to the different players competing to be part of the value creation and capture. This thesis attempts to capture a holistic view of the entire ecosystem and performs a stakeholder value network analysis on the ecosystem and its members. The qualitative model lists, maps and identifies the stakeholders and the monetary, goods / services, information, participation and public benefit value flows between the stakeholders in the ecosystem. The quantitative model attaches numerical values to the different value flows based on a characterization of needs and the importance of the sources fulfilling those needs and creates a value network that is then analyzed to produce relative importance of stakeholders from various perspectives and a ranking of the importance of different types of direct and indirect value flow loops in the system thus creating a framework for strategic ecosystem analysis.
