Study Notes
Methodology
- A formalized approach or series of steps to achieve a particular goal
- Necessary for large programs, as writing code without a well-thought-out system may not work
Structured Design
- A methodical approach where projects move from one step to the next
- Each step is typically finished before the next one begins
Waterfall Method
- Identifies system requirements early in the development process
- Design must be fully specified on paper before programming begins
- Long time between system proposal and delivery of new system
Alternatives to SDLC
Rapid Application Development (RAD)
- A software development model based on prototyping and quick feedback
- Emphasizes iterative design and construction process to accomplish more in less time
Phased Development
- A development project divided into several phases
- Each phase ends with a defined output
- Phases are performed in a specified order
- Breaks down software development into manageable parts to reduce cost and complexity
