A Practical, Start-to-Finish Approach to Managing, Evolving, and Transforming Legacy IT Systems For every IT executive, manager, architect, program leader, project leader, and lead analyst aRichard and Kevin introduce us to a reality thatas often neglected in our industry: the problem of evolving legacy systems, a domain they call aBrownfield development.a The authors identify the root of the problem as that of complexity, and offer an approach that focuses on the fundamentals of abstraction and efficient communication to nibble at this problem of transformation bit by bit. As the old saying goes, the way you eat the elephant is one bite at a time. Richard and Kevin bring us to the table with knife and fork and other tools, and show us a way to devour this elephant in the room.a Grady Booch, IBM Fellow, co-creator of UML aMost organizations in the 21st century have an existing, complex systems landscape. It is time that the IT industry face up to the reality of the situation and the need for new development methods and tools that address it. This book describes a new approach to the development of future systems: a structured approach that recognizes the challenges of aBrownfielda development, is based on engineering principles, and is supported by appropriate tooling.a Chris Winter, CEng CITP FBCS FIET, IBM Fellow, Member of the IBM Academy of Technology Most conventional approaches to IT development assume that youare building entirely new systems. Today, aGreenfielda development is a rarity. Nearly every project exists in the context of existing, complex system landscapes--often poorly documented and poorly understood. Now, two of IBMas most experienced senior architects offer a new approach that is fully optimized for the unique realities of aBrownfielda development. Richard Hopkins and Kevin Jenkins explain why accumulated business and IT complexity is the root cause of large-scale project failure and show how to overcome that complexity aone bite of the elephant at a time.a Youall learn how to manage every phase of the Brownfield project, leveraging breakthrough collaboration, communication, and visualization tools--including Web 2.0, semantic software engineering, model-driven development and architecture, and even virtual worlds.
