Lesson Plan

• Describe the four stages of the product life‑cycle and their key characteristics.
• Explain how different extension strategies can prolong a product’s market presence.
• Apply the decision‑making framework to evaluate costs, benefits and risks of extension options.
• Analyse a real‑world case to select the most appropriate extension strategy.
• Compare product‑, market‑, pricing‑ and promotional‑related extensions.

• Projector and laptop for presentation
• Printed PLC diagram handout
• Smartphone case study worksheet
• Calculators
• Whiteboard and markers
• Exit‑ticket slips

Begin with a quick poll: “Which of your favourite gadgets is no longer on the shelves?” Use this to recall the concept of a product’s life‑cycle. Review the four PLC stages and set the success criteria: students will be able to map a product onto the PLC, identify suitable extension strategies, and justify a chosen strategy using a simple cost‑benefit analysis.

1. Do‑now (5’) – short quiz on PLC stages displayed on the board.
2. Mini‑lecture (10’) – present the PLC diagram, highlight sales/profit trends and key marketing focus for each stage.
3. Group case analysis (15’) – students work in fours on the smartphone decline scenario, fill out the decision‑making framework table.
4. Whole‑class debrief (10’) – each group shares its recommended extension and rationale; teacher highlights good practice.
5. Extension‑strategy brainstorm (10’) – quick whole‑class listing of product, market, pricing and promotional extensions with real examples.
6. Check for understanding (5’) – exit‑ticket: “Name one extension strategy you would use for a product in the maturity stage and why.”

Summarise how the PLC informs strategic decisions and revisit the checklist for extension choices. Collect exit‑tickets to gauge understanding, then assign homework: each student selects a current product, identifies its PLC stage, and proposes an appropriate extension strategy with a brief cost‑benefit justification.
