Enterprise IT architecture made practical--finally!

There's only one way to maximize legacy infrastructure while integrating new partners, technologies, applications, and data streams: begin with a coherent enterprise architecture. But most approaches to enterprise architecture have been far too complex and theoretical--until now. IT Architecture Toolkit is a breakthrough: a practical, simple, rapid, and complete approach to delivering on the promise of enterprise architecture.

Jane Carbone's approach has been proven in mid-market and Fortune 500 enterprises alike. Step by step, Carbone shows how to integrate business, architecture, implementation, and all key outputs: for data, applications, technology, and people. Whether you're an IT leader, architect, planner, or analyst, you'll learn how to:

  • Create strong, auditable links with business drivers
  • Model your architecture simply, easily, and quickly
  • Translate your models to real, manageable projects.
  • Define the value proposition for architecture and establish realistic metrics
  • Achieve buy-in throughout your organization
  • Manage the "soft" aspects of your architecture initiative, including processes, roles, responsibilities, and organizational structure

Carbone provides a "soup to nuts" collection of methods and examples. Using her exercises, you'll construct a complete draft architecture for your own business: one that will handle change, opportunity, growth, mergers, downsizing . . . whatever comes your way.
