Question 1 Easy

Why is "The package should be strong" considered a weak specification?

  • Answer: It is not measurable or testable. A strong specification defines the exact limit, such as: "The package must withstand a vertical load of 15 kg without deforming."
  • Hint: If you can't prove it with a tool (like a scale or a ruler), it isn't a technical specification.

Challenge 1 Hard

The Smartphone Audit: Think about a phone designed specifically for Extreme Outdoor Adventurers.

  • Task: List three "Must-have" specifications and one "Optional" specification for this target user.
  • Solution Example:
  • Must 1 (Safety/Durability): Must be IP68 rated (waterproof to 1.5m for 30 mins).
  • Must 2 (Performance): Battery must last 48 hours on a single charge with GPS active.
  • Must 3 (Size): Must be operable while wearing thick winter gloves (Physical limit).

  • Task: Use the SMART rule to rewrite this into two high-quality specifications.
  • Solution:
    1. Sustainability: "The snack box must be made of 100% biodegradable bamboo fiber."
    1. Ease of Use: "The lid must require less than 5 Newtons of force to open, as measured by a tension gauge, to ensure use by children aged 4–6."
  • Hint: Add a number and a way to test it.
