What is objective evaluation?Show answer
Objective evaluation is based on measurable facts that anyone testing the product would agree on. It uses measurement and testing to produce results that are not a matter of opinion. Examples: the chair supports 120 kg without breaking; the seat height is 440 mm; the torch runs for 6 hours; the bottle does not leak. Objective evaluation proves whether the product meets its functional, safety and dimensional requirements, and it is the backbone of an honest evaluation because it cannot be argued with.
What is subjective evaluation?Show answer
Subjective evaluation is based on opinion and personal judgement. It captures qualities that cannot be measured: comfort, appearance, appeal, how pleasant something is to use. Examples: users find the chair comfortable; the product looks attractive; the colours suit a bedroom. Subjective evaluation reflects the human response to a product, which strongly affects whether people want to buy and use it.
What is matching the method to the quality?Show answer
The skill is choosing the right method for each specification point. Strength, size, weight, battery life and leak-proofing are evaluated objectively by measurement. Comfort, appearance, appeal and ease of use are evaluated subjectively through user opinion (often alongside objective measures like task times). A well-planned evaluation decides, for each point, whether to measure it or to judge it with users.
