Agile Management for Software Engineering: Applying the Theory of Constraints for Business Results (軟體工程的敏捷管理：運用約束理論達成商業成果)

"This book does a good job of describing the methods employed at Sprintpcs.com ... over 250 people practicing Feature Driven Development and reporting their progress to me at the monthly operations review."
--Scott B. Relf, Chief Marketing Officer, Sprint PCS

"A tremendous contribution to the literature in the field. This should be required reading for all development teams going forward."
--John F. Yuzdepski, VP & GM, Openwave Systems

A breakthrough approach to managing agile software developmentAgile methods might just be the alternative to outsourcing. However, agile development must scale in scope and discipline to be acceptable in the boardrooms of the Fortune 1000. In Agile Management for Software Engineering, David J. Anderson shows managers how to apply management science to gain the full business benefits of agility through application of the focused approach taught by Eli Goldratt in his Theory of Constraints.

Whether you're using XP, Scrum, FDD, or another agile approach, you'll learn how to develop management discipline for all phases of the engineering process, implement realistic financial and production metrics, and focus on building software that delivers maximum customer value and outstanding business results.Coverage includes:

• Making the business case for agile methods: practical tools and disciplines
• How to choose an agile method for your next project
• Breakthrough application of Critical Chain Project Management and constraint-driven control of the flow of value
• Defines the four new roles for the agile manager in software projects--and competitive IT organizations

Whether you're a development manager, project manager, team leader, or senior IT executive, this book will help you achieve all four of your most urgent challenges: lower cost, faster delivery, improved quality, and focused alignment with the business.
