Software Development Life Cycle CS Thinking Example 2
Follow the full solution, then compare it with the other examples linked below.
Example 2
mediumCompare the Waterfall and Agile approaches to software development. Give one advantage of each.
Solution
- 1 Step 1: Waterfall completes each SDLC stage fully before moving to the next. It is linear and sequential — you do not go back to earlier stages.
- 2 Step 2: Agile works in short cycles (sprints of 1-4 weeks), delivering small increments of working software. Each sprint includes some analysis, design, coding, and testing.
- 3 Step 3: Waterfall advantage: clear documentation and milestones, good for well-defined projects. Agile advantage: adapts to changing requirements, delivers working software faster.
Answer
Waterfall: linear, thorough documentation, good for stable requirements. Agile: iterative, adaptable, delivers working software in short cycles.
Most modern software teams use Agile because requirements frequently change. Waterfall is still used for projects with fixed requirements, like safety-critical systems.
About Software Development Life Cycle
The structured process of planning, creating, testing, deploying, and maintaining software, typically following phases: requirements gathering, design, implementation (coding), testing, deployment, and maintenance. Different methodologies (waterfall, agile, spiral) organize these phases differently.
