Most software process models don't include, or even consider, the capability of the user. In this book, the authors have developed a capabilities-oriented software process model, which has been formalized in Unified Modeling Language and implemented as a tool. The text explores concepts from selection to assessment to psychology that make up this approach. This handbook adds a valuable contribution to the literature on people-related aspects in software engineering, meeting the challenge of extending software process definitions to more directly address people-related considerations. Step by step, the Handbook guides the reader to incorporate of the individual's capabilities into the software process.
