COMM 335 Lecture Notes - Lecture 4: Software Development Process, Graphical User Interface, Business Process Modeling
Document Summary
Divides system development work into distinct phases. Determines the order of how and when the phases are performed: examples, waterfall methodology & prototype methodology. Plan -> analyze -> design -> build/buy -> install -> deploy. Humans: build/buy = build/buy the system, install = install the new system including hardware and software. Convert data from old system to new system: deploy = operate the new system as users enter data, execute processing, and generate reports. Problems = cannot tell if system satisfies their requirements until its finished. An incomplete version of the system being developed: eg. Prototype is presented to stakeholders(end users) making sure that their requirements are understood correctly by the development team. (cid:1) (cid:1) Model: a representation of selected aspects of certain parts of a. Introduction to modeling (cid:1) (cid:1) (cid:1) certain world for some pragmatic purpose. (cid:1) (cid:1) Representation: it is based on an original. Reduction: it only represents selected aspects of the original.
