Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What is meant by quality in a business context?

    Model answer

    The extent to which a good or service meets the requirements of the customer and is fit for its purpose.

  2. 2

    What is quality control?

    Model answer

    Checking output against a standard, usually by inspecting finished or part-finished goods and removing those that fail.

  3. 3

    What is quality assurance?

    Model answer

    Building quality into every stage of the process so that faults are prevented, with each worker responsible for the quality of what they pass on.

  4. 4

    Distinguish between quality control and quality assurance.

    Model answer

    Quality control detects faults after they have been made by inspecting output, while quality assurance prevents them by designing the process and working practices so that faults do not arise.

  5. 5

    Give two reasons a business inspects output before despatch.

    Model answer

    To stop defective goods reaching customers and damaging the brand, and to identify where in the process faults are arising so that the cause can be corrected.

  6. 6

    What is the drawback of relying on end-of-line inspection alone?

    Model answer

    The materials and labour in a defective unit have already been paid for by the time it is found, so waste is discovered rather than prevented.
