Grade: Date: 17/01/2026
Subject: Design and Technology
Lesson Topic: Strategies to evaluate how well a manufacturing system has worked.
Learning Objective/s:
  • Describe the principal quantitative indicators used to evaluate manufacturing performance (efficiency, availability, performance, quality, OEE, cost per unit, waste ratio).
  • Calculate these indicators from a set of production data using appropriate formulas.
  • Analyse indicator results to pinpoint performance gaps and trends.
  • Apply root‑cause techniques (Pareto, fishbone, 5 Why) to explain identified shortfalls.
  • Formulate realistic improvement actions based on the evaluation outcomes.
Materials Needed:
  • Projector and screen
  • Whiteboard and markers
  • Student worksheets with sample production data
  • Calculators
  • Laptops/computers with spreadsheet software
  • Printed OEE formula sheet
  • Post‑it notes for brainstorming
Introduction:

Begin with a short video clip showing a factory dashboard and ask students what “good performance” looks like. Link this to their prior knowledge of production planning and the need for measurable targets. Explain that today they will learn how to quantify system performance and use the results to drive improvement. Success criteria: students will accurately calculate key indicators and propose evidence‑based actions.

Lesson Structure:
  1. Do‑now (5'): Quick quiz on the difference between planned and actual output.
  2. Mini‑lecture (10'): Introduce the seven core indicators and the OEE formula, using the projector.
  3. Guided calculation (15'): In pairs, students input the example data into a spreadsheet and compute each indicator.
  4. Interpretation discussion (10'): Whole‑class analysis of the results, highlighting where performance falls short.
  5. Root‑cause activity (10'): Groups create a fishbone diagram (or 5 Why) to explore reasons for low OEE.
  6. Improvement planning (10'): Each group proposes two realistic actions, records them on post‑its, and shares.
  7. Exit ticket (5'): Write one indicator they consider most valuable and why.
Conclusion:

Recap the key indicators and how they feed into the OEE calculation. Collect exit tickets to gauge understanding and remind students that the next lesson will involve applying these strategies to a real‑world case study. For homework, ask them to gather simple production data from a household or hobby activity (e.g., baking, printing) and calculate at least three indicators.
