Enterprise architecture at work

Meer over het boek

An enterprise architecture aims to describe and control an organization’s structure, processes, applications, systems, and techniques in an integrated manner. Achieving a clear specification of components and their interrelations requires a coherent architecture modeling language. Lankhorst and his co-authors introduce such a language that encapsulates the complexity of architectural domains and their relationships, enabling the construction of integrated enterprise architecture models. They provide architects with practical tools to enhance their architectural practice and present techniques for effective communication with relevant stakeholders. The architecture model serves not only to provide insights into current or future situations but also to evaluate the transition from ‘as-is’ to ‘to-be.’ The authors outline analysis methods for assessing both the qualitative impacts of architectural changes and quantitative aspects, including performance and cost considerations. The modeling language and techniques discussed have been validated through numerous real-life case studies. This resource is an invaluable companion for enterprise IT or business architects in industry and for students in computer or management science studying enterprise architecture.
