Software Development Life Cycle CS Thinking Example 3
Follow the full solution, then compare it with the other examples linked below.
Example 3
mediumA school wants a new student attendance system. For each SDLC stage, describe one specific activity that would be performed.
Solution
- 1 Step 1: Analysis: interview teachers about current attendance process. Design: create database schema for students and attendance records. Implementation: code the attendance entry form.
- 2 Step 2: Testing: verify that marking a student absent updates the database correctly. Deployment: install the system on school computers. Maintenance: add a feature for parents to receive absence notifications.
Answer
Each SDLC stage has a specific deliverable: requirements document, design diagrams, working code, test results, deployed system, ongoing updates.
Applying the SDLC to a real project shows how each stage contributes. The analysis stage is especially critical — building the wrong thing is worse than building it wrong.
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.
