"EA originated from and is influenced by a number of business areas: The manufacturing industry, with Material Requirements Planning (MRP) and later Manufacturing Resource Planning (MRP II). These approaches developed into the so-called supply chain or value chain (Porter, et al). Not only the incoming logistics and internal operations were considered, but also the flow of material to customers and back. The second origin of EA growth was from Process Modelling and Design approaches, e.g. Business Process Re-engineering (Hammer, et al). These approaches seek to depict the enterprise in terms of business processes, leading to process improvements and “end-to-end” process integration. Corporate and process governance, organisational adaptability and IM/IT system integration were typical considerations. Organisations were consequently often restructured, to become “flatter” (less management layers) and coined process-centred or process-oriented organisations. A third development is a type of backward integration where software developers trie to better understand and serve the business world with “functioning and value-adding” software solutions (business applications). It is a well-known fact that enterprise integration software (ERP, etc.), according to business users and owners, are often considered to be failures."
