Superior software productivity requires a relentless focus on people, motivation, and communication. In Improving Software Development Productivity, world-renowned software engineering expert Dr. Randall W. Jensen introduces a proven, quantitative approach to achieving this focus. Jensen helps you measure your organization’s capacity and productivity, and then use that information to improve multiple facets of developer and team performance, and to build more accurate estimates and schedules.
Focusing on management as the principal cost and schedule driver in software projects, he demonstrates a powerful tool based on his Jensen II (Seer) model: the model that underlies many leading software estimation tools. Through real case studies, you’ll learn how to predict the productivity impact of any major management decision, and quantitatively support a transition to “extreme” or “agile” software development environments.
For decades, Jensen has been the industry’s go-to expert on improving software project productivity. This book distills his insights and gives you the tools and knowledge to apply them.
