introduction
Introduction
  • Object-oriented analysis is gaining in popularity
  • O-O designs translate very well into O-O programming languages, such as C++ and Java

Rapid Application Development
  • Overview
    • Group approach
    • Complete four-phase life cycle
    • Much prototyping and user involvement
    • Focus on working model

Rapid Application Development
  • RAD Advantages and disadvantages
    • Advantages
      • Fast and less expensive
    • Disadvantages
      • Focus is on methodology, not business needs
      • Fast design time may lower quality

Overview of Microsoft Solutions Framework
  • Objectives is to define and analyze business requirements and provide IT solutions
  • MSF is the plan and build phase
  • Microsoft Readiness Framework (MRF) is the prepare phase
  • Microsoft Operations Framework (MOF) is the manage phase
  • BAIT model – business, applications, information, technology

MSF Models
  • Risk management model
    • Risk is inherent in all projects
    • Risk is not necessarily bad or good
    • Risk should be managed, not feared
    • Risk involves technology, people, and processes
