Enterprise IT Architecture Essay - 573 Words

Zachman was one of the pioneers of enterprise IT architecture. His article, Business Systems Planning and Business Information Control Study: A comparison†, was an early effort to suggest that businesses should think more carefully about how they integrated systems and data. He used the analogy of architecture, since, as Hurley and Tompkins summarise, â€Å"each stage in the building of a house requires different levels of detail. At each stage, decisions need to be made about what materials compromise the product, how it will work, where the components are located, who is involved, when tasks need to be completed, and why they are important† (Hurley and Tompkins, 1999:76). This was developed in the early 1990’s by authors like Wiley, who†¦show more content†¦Information technology strategy theorists have also commented on this disparity between plan and information, such as Gottschalk (Gottschalk 1999a). In fact, Gottschalk attempted to address this issu e with his ‘strategy implementation matrix’, which tried to resolve the disparity by appeal to enterprise resource planning (Gottschalk 1999b). M. J. Earl wrote on information system strategy, and argued that there were five different models: business-led, method-driven, administrative, technological, and organisational (Earl 1990:181). He argued that organisational was the best, which is the system that treats strategic information system planning as being â€Å"based on IS [information systems] decisions being made through continuous integration between the IS function and the organization.† (Earl 1990:195) One interesting development of this that links Earl’s work with later IT Architecture theory is the work by Kanungo, Sadavarti and Srinivas, which, via a case study of the Indian public sector, draws connections between strategy implementation and organisational culture (Kanungo, Sadavarti and Srinivas, 2001). What can be concluded from this literature is that the term ‘Enterprise IT Architecture’ has evolved to mean something quite distinct from other concepts. This is confirmed by discussions had with IT professionals, who understand it to refer to the synthesis of all the organisation’s assets, which includes (but is notShow MoreRelatedEnterprise Architecture : Business Architecture1206 Words   |  5 PagesEnterprise Architecture IA-3 2.
