  1. MBI 630: Week 12 Finalizing Design Specifications 1/5/2020

  2. Week 12: Finalizing Design Specifications • Finalizing Design Specifications • Structure Charts • Rapid Application Development (RAD) • Video "Application Engineering" • Broadway Entertainment Co. Inc., Case • Group Discussion

  3. The Process of Finalizing Design Specifications • Deliverables and Outcome • Set of physical design specifications, which contains detailed specifications for each part of the system • Database • Input forms & output reports • Interface • Software structure?

  4. Representing Design Specifications • Structure Charts • Shows how an information system is organized in hierarchical modules • Shows how parts of a system are related to one another • Shows breakdown of a system into programs and internal structures of programs written in third and fourth generation languages

  5. Structure Charts

  6. Representing Design Specifications • Prototyping • Construction of the model of a system • Allows developers and users to • Test aspects of the overall design • Check for functionality and usability • Iterative process • Two types • Evolutionary Prototyping • Throwaway Prototyping

  7. Rapid Application Development • Systems development methodology created to radically decrease the time needed to design and implement information systems radically. • Five key factors • Extensive user involvement • Joint Application Design sessions • Prototyping • Integrated CASE tools • Code generators
