Framework for Systems Development Life Cycle (SDLC) that details the stages of information system development
Phases: Analysis, Design, Implementation, and Evaluation Testing
<h3>What are predictive models associated with the SDLC?</h3>
- Waterfall Model
- Stages of system development and support that are clear and logical
- Assumes that needs will stay stable after they are defined
- Spiral Model Admits that most software is produced iteratively or spirally, as opposed to linearly.
- Later in the cycle, the project team is receptive to adjustments and revisions.
- Allows for the gradual creation of functional software, with every new release bringing additional features.
- Prototyping Model
- Rapid Application Development (RAD) Model is a technique for creating software prototypes to explain user requirements for operational software.
- Utilizes a method where developers collaborate on a developing prototype
