These sources collectively address the topic of Enterprise Architecture (EA), primarily through the lens of The Open Group Architecture Framework (TOGAF). The pocket guide provides a comprehensive overview of TOGAF Version 9.1, detailing its structure, the phases of the Architecture Development Method (ADM), and key concepts such as Architecture Views and Architecture Viewpoints. A discussion thread from Reddit attempts to clarify the distinction between the Architecture Viewpoint (the perspective) and the Architecture View (the resulting representation) for stakeholders, often relying on practical analogies. Finally, a case study demonstrates the practical application of the TOGAF ADM to improve the business processes of a car spare parts distributor, PT Dirgamitra Pacific, by designing a new integrated website system to replace inefficient manual and disparate processes.
