Developing Enterprise Architecture for Railway Machinery Engineers

Abstract

This thesis presents an analysis of the machinery department organization at the Central Japan Railway Company (CJR) with the aim of enhancing the company's resilience in response to ecosystem and stakeholder changes, as well as the impact of technological advancements on company operations. Based on the publication review of cutting-edge maintenance-related technologies, theories, and contract types, this study uses the Architecting Innovative Enterprise Strategy (ARIES) framework to analyze the machinery department of CJR as an enterprise. ARIES models the enterprise from holistic views including ecosystem landscape analysis, and stakeholder analysis, and generates an architectural concept.

The study suggests that a direct maintenance strategy in collaboration with academic research would be a more flexible and resilient enterprise architecture than the current architecture. This new enterprise architecture is expected to deliver better value to both internal and external stakeholders. Finally, the study validates this generated enterprise architecture using evaluation criteria such as the Pugh matrix and future-proofing scenario analysis.
