Description

Developing IT architectures that enable e-Business: the practical, concise guide!

  • Key high-level principles and guidelines for e-Business architecture.
  • Covers every stage of the solution-building process: the activities involved and how they fit together.
  • Why e-Business architectures are fundamentally different from anything that has come before.
As all business becomes e-Business, managers and IT professionals must implement IT architectures that are effective, flexible, resilient enough to handle relentless change, growth, and acceleration -- or risk becoming uncompetitive virtually overnight. Written for both managers and technical professionals, E-Business and IS Solutions: An Architectural Approach to Business Problems and Opportunities offers complete, high-level guidance for defining and implementing IT architectures that enable e-Business instead of standing in its way. The book demonstrates the benefits of an architecture-based approach to e-business, and shows managers how to design effective e-Business architectures and infrastructure for their organizations. William J. Buffam reviews the core principles and practices associated with applying e-Business technology for competitive advantage, walks through each key activity needed to define an effective e-Business architecture, and presents powerful solutions for unique challenges of designing IT infrastructure for e-Business applications. For all managers and IT professionals involved with e-Business strategy, implementation, or IT architecture, including architects, analysts, strategists, project managers, developers, and many others.

William J. Buffam heads up the Unisys Architectural Center of Excellence in Malvern, Pennsylvania. A graduate of the University of Manchester, his perspective of information technology has been shaped by many years of endeavor as solutions architect, software engineer, technology specialist, manager, and educator. During leisure hours, you'll likely find him soaring high in the sky on his hang glider, keeping the world in proper architectural perspective.
