Large IT organizations are increasingly willing to purchase "commercial off-the-shelf" (COTS) products built on open systems rather than building software from scratch. However, along with the potential advantages of speed to market, reliability, and lower cost, acquiring software brings it own complex management challenges. In Managing Software Acquisition, two leading experts in acquiring enterprise software review those challenges -- and offer new best practices for purchasing and implementing open-systems-based COTS software solutions.KEY TOPICS:Managing Software Acquisition is based on extensive new research at the Software Engineering Institute, the world's leader in defining best practices for software quality. SEI researchers Meyers and Oberndorf begin by reviewing the key elements and attributes of open systems and COTS software, the promise of approaches that minimize custom development -- and the risks. Define reference models and architectures based on open, off-the-shelf solutions; understand how to evaluate and compare standards; then, walk through a start-to-finish roadmap for transitioning to open systems and COTS-based software acquisition. Finally, gain an in-depth understanding of how COTS software implementation is different from traditional IT project implementation -- and the significantly different management skills needed for success. Managing Software Acquisition includes a detailed glossary, IT self-assessment questions, and extensive references to additional information.MARKET:For all IT professionals involved with choosing and implementing software strategies, including software architects and analysts, project managers, developers, and IT managers.

The acquisition of open systems and commercial off-the-shelf (COTS) products is an increasingly vital element of corporate and government software development. Properly managed software acquisition offers potential for significant time and cost savings over a system's lifetime. The transition from proprietary, custom-built systems to systems based on standards and commercial products is not easy, however. Managers and their staff must understand the risks and opportunities associated with this acquisition approach.

Managing Software Acquisition presents the fundamental principles and best practices for successful acquisition of open, COTS-based systems. It explores the many opportunities and challenges of this approach, defines key terms, anticipates potential problems, and discusses the effect of software acquisition on the manager's job. The information presented addresses critical concerns affecting the entire software industry; it also discusses important issues particular to government acquisition.

Managing Software Acquisition moves from a broad overview of the topic to experience-based advice on managing the transition and more detailed information on acquisition. You will find coverage of such topics as:
  • Promises and pitfalls of open, COTS-based system acquisition
  • Implications for industry and government--quality, loss of control, and risk
  • Reference models, architectures, and standards for open systems and COTS products
  • Implications for cost, schedule, performance, and staff
  • Engineering practices, including defining requirements, integration, testing, deployment, and support
  • Contracting strategies and relationships with vendors
  • Integrated acquisition using standards and COTS products

Each major section concludes with realistic, open-ended exercises that illustrate vital issues confronting software acquisition managers. In addition, the book includes an extensive reference section containing a glossary, list of acronyms, sample questions to help organizations evaluate their needs, and more.
