| Subject: Information Technology IT |
| Lesson Topic: Analyze maintenance types (corrective, adaptive, preventive) |
Learning Objective/s:
- Describe the purpose and triggers of corrective, adaptive, and preventive maintenance.
- Compare the typical activities and key metrics for each maintenance type.
- Analyse a scenario to select the most appropriate maintenance approach.
- Evaluate how maintenance decisions affect system reliability and business continuity.
|
Materials Needed:
- Projector or interactive whiteboard
- Slide deck summarising maintenance types
- Case‑study handouts with system scenarios
- Whiteboard and markers
- Demo access to a bug‑tracking tool (e.g., JIRA)
|
Introduction:
Begin with a quick poll: “When an app you use crashes, what happens next?” Connect this to prior learning on the system life‑cycle and explain that today’s success criteria are to identify triggers, describe activities, and choose the correct maintenance type.
|
Lesson Structure:
- Do‑now (5’): Students list recent technology changes they’ve experienced and share examples.
- Mini‑lecture (10’): Overview of corrective, adaptive, and preventive maintenance with real‑world examples; display comparison table.
- Guided analysis (15’): Small groups work through a case study, identify the trigger, propose a maintenance type, list typical activities, and note relevant metrics.
- Whole‑class debrief (10’): Groups present findings; teacher clarifies misconceptions and completes a decision‑flowchart on the board.
- Quick check (5’): Exit ticket – write one key difference between corrective and preventive maintenance.
|
Conclusion:
Recap how each maintenance type contributes to system longevity and business goals. Students complete an exit ticket stating which maintenance type they would prioritize for a legacy system. For homework, research a recent real‑world incident and describe the maintenance response that was applied.
