Enterprise Architecture at Work: Modelling, Communication and Analysis, 3/e (Hardcover)

An enterprise architecture tries to describe and control an organisation’s structure, processes, applications, systems and techniques in an integrated way. The unambiguous specification and description of components and their relationships in such an architecture requires a coherent architecture modelling language. Lankhorst and his co‑authors present such an enterprise modelling language that captures the complexity of architectural domains and their relations and allows the construction of integrated enterprise architecture models. They provide architects with concrete instruments that improve their architectural practice. As this is not enough, they additionally present techniques and heuristics for communicating with all relevant stakeholders about these architectures. Since an architecture model is useful not only for providing insight into the current or future situation but can also be used to evaluate the transition from ‘as‑is’ to ‘to‑be’, the authors also describe analysis methods for assessing both the qualitative impact of changes to an architecture and the quantitative aspects of architectures, such as performance and cost issues. The modelling language presented has been proven in practice in many real‑life case studies and has been adopted by The Open Group as an international standard. So this book is an ideal companion for enterprise IT or business architects in industry as well as for computer or management science students studying the field of enterprise architecture.

企業架構試圖以一種整合的方式描述和控制組織的結構、流程、應用、系統和技術。在這樣的架構中，對組件及其關係的明確規範和描述需要一種一致的架構建模語言。Lankhorst及其合著者提出了一種企業建模語言，可以捕捉架構領域及其關係的複雜性，並允許構建整合的企業架構模型。他們為架構師提供了具體的工具，以改進他們的架構實踐。由於這還不夠，他們還介紹了與所有相關利益相關者溝通有關這些架構的技術和啟發法。由於架構模型不僅有助於了解當前或未來情況，還可以用於評估從“現狀”到“目標”之間的過渡，作者還描述了評估架構變化的定性影響和性能、成本等定量方面的分析方法。所介紹的建模語言在許多實際案例研究中得到了驗證，並被The Open Group採納為國際標準。因此，本書對於業界的企業IT或業務架構師以及研究企業架構領域的計算機或管理科學學生來說是一個理想的伴侶。
