Document Summary

Why systems fail: 20% of systems succeed, 80% fail. Skipping sldc phases (take short cuts in designing) Failure to manage project scope, the details (scope creep and feature creep) Failure to manage project plan (larger budget issues) When building an information system you are influencing organizational change and need to understand risk ex) hub, shifted from old to new. Information systems planning- needs to support organization mission. Organization mission (everyone needs to be aligned) Is strategic plan, works with organization strategic plan ex) voice of ip upgrade for ub 2020. New information technology architecture- need architecture in place to support strategic plan ex) ub voice over ip system, but network was not up to par, so upgraded equipment on campus. Sdlc- the development method used by most organizations today for large, complex systems. Waterfall approach- a sequence of steps in the sdlc with cycles returned to previous stops.
