**Module 5: Enterprise Architecture Methods** **Overview** **Lesson Outcomes** - - - **Lesson1: Evolution of Systems Development Methodology** **Evolutions of Software Engineering** **Evolution of Information Engineering** **Evolution of Object-Oriented Methods** - Strategy A: Implementation in top-down, rigorous detail; - This strategy achieves enterprise-wide data integration with a fully attributed, fully normalized logical data model. It identifies architecturally normalized business processes before they are submitted for applications design and development deliverables. The time and cost savings of this strategy---when compared to traditional systems development methods---are impressive. - Strategy B: Selective EA, based on ROI business case; - Strategy B is appropriate if an ROI business case must first be established before a decision is made to introduce an enterprise architecture approach. This strategy evaluates the ability of legacy systems to support required data, processes, organizational structure, and business plan relationships. It assesses the benefits and trade-offs of enterprise architecture to address the needs for the future and prioritize the systems that should be addressed. The business case can then be established for enterprise architecture. The most appropriate enterprise architecture implementation approach can be selected. - Strategy C: Deliver progressively in 3-month incremental builds. - This approach leads to incremental implementation of priority areas that are needed first, before other areas that can wait until later. This approach enables strategic business plans for the future to be defined using the strategy analysis methodology of enterprise engineering. The business plans are used to identify data and information that are required for the future. This is documented in a strategic model, which is a high-level enterprise model that achieves enterprise-wide data integration. - - - - - **Assessment** 1. 2. 3.
