Lesson Plan

• Describe the characteristics, typical uses, advantages and disadvantages of direct changeover, parallel running, pilot running and phased implementation.
• Compare the four methods in terms of risk, cost and implementation speed.
• Evaluate which implementation method best suits a given organisational scenario.
• Apply decision‑making criteria to recommend an appropriate implementation approach.

• Projector and screen
• Whiteboard and markers
• Printed handouts summarising the four methods
• PowerPoint slide deck
• Case‑study worksheets for group work
• Sticky notes / index cards for brainstorming

Begin with a quick poll: “What’s the biggest challenge when a new system replaces an old one?” Connect this to the previous lesson on the Systems Development Life Cycle. Explain that today’s success criteria are to identify each implementation method and justify the most suitable choice for a given scenario.

1. Do‑now (5’) – Short quiz on the SLCT phases to activate prior knowledge.
2. Mini‑lecture (10’) – Present the four implementation methods using slides and the comparison table.
3. Guided analysis (10’) – Students complete a worksheet matching advantages/disadvantages to each method.
4. Group case study (15’) – In small groups, analyse a provided organisational scenario, choose the best implementation method, and record justification.
5. Whole‑class debrief (5’) – Groups share decisions; teacher highlights key differences and correct misconceptions.
6. Exit ticket (5’) – Individually write one advantage and one risk of the method they selected.

Recap the four methods, emphasizing how risk, cost and speed influence the choice. Collect exit tickets to gauge understanding, and remind students to complete the homework: research a real‑world system implementation and write a brief report outlining the method used and why it was appropriate.
