Chapter 5: 2) Modeling approach commonalities for structured analysis and information engineering – Both are model driven and both use the same data flow diagrams. Both attempt to synchronize data and process models. Fundamental differences- Structured analysis focuses on the flow of data though the business and software processes. With this, the process models are drawn first. Information engineering focuses on the structure of stored data and the data models are drawn first. 5) To assist Joseph, I recommend using an accelerated systems analysis approach with CASE tools. He can generate a system model or a system prototype. He can then reverse engineer the system to generate what he needs. 21) It is necessary to continually update the project plan in order to make sure the project plan is reflecting the true status. Because the project scope can be a moving target and if there are delays, changes or anything that could change the timeline or budget, it must be reflected in the project plan. Chapter 6: 1) A requirements error gets more costly to fix later in the project because of longer delivery times, additional costs of redevelopment due to the system not meeting users expectations, the system may be unreliable as well as a cost to the reputation of IT for not delivering a working system on time and on budget. The longer into the process that errors are discovered
