How would you feel if you visited your financial planners office and saw past-due credit card notices on their desk? Would you trust an auto mechanic whose car backfires and produces black smoke? A dentist with bad teeth? A banker in shabby clothes?An interior designer whose offices are a shambles? This is the position of the IT capability in many large organizations. The designated custodian of critical business processes and data does not manage its own processes and data reliably. A response in the form of Enterprise Resource Planning for Information Technology is emerging from major companies, research firms, and vendors; they are labeling these offerings "ERP for IT," IT Resource Planning, and related terms. This groundbreaking, practitioner-authored book provides an independent examination of and response to these developments. An analysis of the large scale IT capability, with specific attention to business processes, structured data, and enabling systems, it is essentially acomprehensive systems architecture, not for the business capabilities IT supports, but for IT itself.
