Résumé
And with this new attention comes a pragmatic guide to proven industry practices for emerging and fulfilling customer requirements. More than just an idealized view of the topic, Effective Requirements Practices addresses both managerial and technical issues that determine the success--or failure--of a project. The requirements practices described in this book enable you to redirect resources to satisfy customers' real business needs. Together, these practices provide a proven framework and process that help keep projects on the right track and ensure that requirements are addressed properly throughout a project's life cycle.
This book demonstrates proven methods and techniques. Topics covered include
- Strategies and methods for getting to the "real" customer requirements
- Developing and improving a requirements process
- The roles and responsibilities of the Joint Team for requirements elicitation
- Designing system requirements with the system architecture in mind
- Maintaining effective communication among team members
- Maintaining a set of work products
- Requirements verification and validation
- Accommodating changes in requirements throughout the project
- How the recommended requirements practices utilize the Capability Maturity Model (CMM) framework
- Achieving an environment of continuous improvement and mutual support of one another
- Also provided is a sample process that has been used in industry and deployed and tailored on dozens of projects. In addition, Effective Requirements Practices offers you recommendations for incorporating industry best practices into the development effort.
