Definition
A linear approach where each stage (requirements, design, development, testing, installation, maintenance) is finished before the next starts, like falling water. Advantages: clear structure and documentation. Disadvantages: hard to change, late testing. Suits large, well-defined projects.
Example: Fixed requirements and a big government system suit Waterfall.
Found in: school notes.
Sequential, plan-driven phases.

How to use it
A model sentence
“A linear approach where each stage (requirements, design, development, testing, installation, maintenance) is finished before the next starts, like falling water.” Then apply it: Fixed requirements and a big government system suit Waterfall.
In a short answer, give the definition in your own words first, then tie it to the situation in the question. Do not copy the example above unless it fits the scenario.

Quick multiple choice
Which development approach is a hybrid of Waterfall and Agile?
- Parallel
- Direct
- Pilot
- WAgile
Show the answer
D
WAgile combines upfront Waterfall planning/requirements with Agile iterative development. Pilot, parallel and direct are implementation methods, not development approaches.
