(Sequential phases with defined outputs
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
Learn about different methodologies like structured design and the waterfall method in software development. Understand the pros and cons of using each approach.
