In new economics such as high-tech, knowledge-driven industries, the competitive game changes frequently and dramatically. Two maxims are widely accepted in these markets: 1. it pays to hit the market first. 2. it pays to have superb technology. These industries face a high change and high speed competitive business environment. Information systems of these firms often have to be modified or created based on imprecise requirements or even conceptual ideals. According to past research literature, precise requirement is one of the key success factors for software development outsourcing. Imprecise requirements indicate uncertain project scope and tend to risk. This research of imprecise requirement software development outsourcing base on Adaptive Software Development and Incomplete Contract theory. A case study is used to analyze below imprecise requirement software outsoucing issues issues in a semiconductor foundry MES project: 1. How to deliver a usable system to achieve project goals from imprecise requirements? 2. How to manage frequent change ascribed to imprecise requirements? 3. How to manage project escalation and cost issue ascribed to imprecise requirement?

A distributed online curriculum and courseware (DONC2) development model is proposed in this study. Collaborative courseware development teams which may work in distributed academic or private institutions who need to develop higher quality, reduced cost, on time products are the users of DONC2 development model. The related features from the disciplines of instructional design and software engineering were combined and concepts like usability, especially in terms of formative and summative evaluation, interoperability and reusability were integrated into the model. The research is conducted as a collective case study, including four cases with distinctive characteristics to reveal the several practices in online curriculum and courseware development work. The DONC2 development model was proposed using the results gathered from the investigated cases and a literature survey. The model uses the iterative incremental and agile software development approaches in order to overcome the disadvantages of other linear system development approaches. This enables building releasable products in short time periods with increased quality. Furthermore, continuous communication, evaluation and feedback as well as good project management and readiness to adapt to changes are integrated as the essential characteristics. DONC2 development model is different than previous linear and non-adaptive models in all of these aspects.

Com objetivo de viabilizar entregas frequentes, processos adaptáveis, flexíveis e focados no cliente, as metodologias ágeis se tornaram referência sobre como produzir software de forma produtiva. Contudo, com objetivo de tornar o processo mais simples, essas abordagens invariavelmente incorrem em problemas como: modelos pouco generalistas para cobrir todo o ciclo de vida da Engenharia de Software; foco em disciplinas específicas do processo de software; subestimação de aspectos relevantes em iniciativas de desenvolvimento, como esforços de arquitetura, design e documentação; e indicação para equipes e projetos de pequena escala. A proposta desta dissertação de mestrado é propor um framework de processo eficiente de desenvolvimento de software, o qual se baseia nos ideários das metodologias ágeis, porém cobre todo o ciclo de vida de projeto desde a concepção, gestão, implementação e entrega. O framework inclui ferramentas como princípios, valores, atividades, artefatos e práticas específicas, incluindo esforços como arquitetura, design e documentação, concebendo um processo ágil, eficiente e extremamente produtivo para projetos de concepção e manutenção software, independentemente da sua escala.
