The 20 questions

  1. What is the first step when testing design ideas against a specification?

    • Discard the prototype
    • Advertise the item
    • Package the product
    • Plan measurable tests

  2. Why should a designer test an idea against a written specification?

    • Reduce product mass
    • Speed up manufacturing
    • Lower retail price
    • Judge requirements objectively

  3. How should a designer test if an egg box survives a 1 m drop?

    • Weigh empty packaging
    • Measure box thickness
    • Perform a drop test
    • Calculate box volume

  4. What must a designer record during prototype testing?

    • Advertising budgets
    • Worker wages
    • Factory rent
    • Specification results

  5. What action follows a prototype failing a specification point?

    • Stop all production
    • Redesign and retest
    • Ignore the failure
    • Sell the product

  6. Which method measures the physical strength of a manufactured joint?

    • Electrical resistance test
    • Visual colour check
    • Thermal imaging scan
    • Loading with weights

  7. What is the best way to test if a product is waterproof to 1 m?

    • Inspect colour
    • Measure dimensions
    • Weigh the product
    • Submerge and check

  8. What is essential to ensure a practical test is completely fair?

    • Use multiple testers
    • Control all variables
    • Vary testing times
    • Change test locations

  9. Why is it important to repeat a prototype test multiple times?

    • Check consistency
    • Increase speed
    • Change colour
    • Reduce mass

  10. A test gives results of 4.8 s, 5.2 s and 5.0 s. What is the mean time?

    • 5.2 s
    • 4.8 s
    • 15.0 s
    • 5.0 s

  11. Which of these is an example of a quantitative test result?

    • 350 cycles
    • feels smooth
    • looks weak
    • bright red

  12. Why should testing conditions always be recorded carefully?

    • To speed production
    • To lower costs
    • To allow replication
    • To save materials

  13. What is a major limitation of using card for a functional prototype?

    • Different material properties
    • It is heavy
    • It is opaque
    • It is magnetic

  14. A switch survives 5,000 uses in a test. What does this demonstrate?

    • Target durability
    • Electrical safety
    • Thermal mass
    • Total waterproofing

  15. Which method best checks if a product meets a comfort requirement?

    • Tensile strength test
    • Electrical resistance
    • User rating scale
    • Weighing the item

  16. What is the main purpose of a control in a fair test?

    • Increases the voltage
    • Reduces material cost
    • Speeds up testing
    • Provides a baseline

  17. Why is a test that fails a specification point still useful?

    • Lowers prototype cost
    • Highlights design flaws
    • Saves manufacturing time
    • Eliminates all errors

  18. A prototype is 20 percent too heavy. What is the best next step?

    • Change the label
    • Sell it anyway
    • Ignore the weight
    • Redesign and retest

  19. Why should testing include the people who will actually use the product?

    • Reveal hidden flaws
    • Design packaging
    • Order raw materials
    • Set retail prices

  20. A product part overheats during testing. What is the immediate next step?

    • Paint it white
    • Increase the price
    • Add more packaging
    • Investigate and modify
