Dear Reader,

This research studies three broad Enterprise Architecture (EA) implementation models in enterprises as published by James Lapalme (2012) in the article: “Three Schools of Thought on Enterprise Architecture”. These schools of thought include:

  • EA for IT Architecting;
  • EA for Enterprise Integrating;
  • EA for Ecosystem Adaptation.

This article expands upon these schools of thought by highlighting the merits and demerits of each. The study also x-rays the EA implementation model adopted in Nigerian National Petroleum Company (NNPC) Limited and its attendant opportunities and drawbacks.

The authors then propose a matrix to guide the selection of suitable EA implementation models based on certain identified organisational characteristics including the enterprise size, regulatory environment and business scope. This research is particularly useful as it builds upon existing knowledge in the EA discipline as well as drawing from the experiential knowledge of the authors, and the review of EA subject matter experts working in a large energy enterprise with multiple subsidiaries (i.e., the NNPC Limited).

This study is suitable for individuals/organisations who are looking to maximise the benefits of EA in their organisations or mitigate/remediate risks often encountered in the implementation of EA as an organisational practice. It is also useful for academic purposes.
