Overview

Effective and efficient use of IT is crucial to all organizations. On the one hand, using IT ineffectively throughout an organization will have a detrimental impact on business. On the other hand, the optimal use of IT puts a huge strain on a corporation's organizational skills to manage all the IT aspects of a business as a coherent whole. Dynamic Enterprise Architecture: How to Make It Work provides step-by-step guidance to designing, implementing, and managing an enterprise architecture with a focus on embedding this architecture throughout the entire organization.

Written by a team of leading enterprise architects, Dynamic Enterprise Architecture introduces DYA® (Dynamic Architecture for modeling and development) (DYA® is a registered trademark of Sogeti Nederland B.V.), a conceptual and practical model to help integrate a successful enterprise architecture system into an organization. Written by a team of innovators in IT architecture, this groundbreaking book provides accessible tools for designing and implementing the architectural processes within a corporation. Featuring a multidisciplinary approach, it's the first book of its kind to structurally address the day-to-day ups and downs that every organization encounters when working under architecture.

The authors present a successful field-tested approach to enterprise architecture that enables corporations to achieve their business objectives faster. The key elements of this approach include multidisciplinary teams, purposeful architectural design, and room for deliberate noncompliance with the standard enterprise architecture. With a close examination of management techniques for correct implementation and maintenance, DYA® combines three processes to help corporations get the full benefits of using enterprise architecture:

  • Strategic Dialog—companies' business objectives are determined and are further defined as project proposals
  • Development with Architecture—IT solutions are implemented
  • Architectural Services—supports the other two processes with principles, guidelines, and models

Complete with useful, tangible tools for implementing and designing the architectural process within a corporation, Dynamic Enterprise Architecture enables business and IT managers, controllers, CIOs, COOs, and CTOs to make major contributions to achieving the business objectives of their organizations.
