Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    Distinguish between quality control and quality assurance.

    Model answer

    Quality control inspects output at the end of the process to remove defective items, while quality assurance builds checks into every stage so that defects are not produced in the first place.

  2. 2

    Define Total Quality Management.

    Model answer

    Total Quality Management is an approach in which every employee takes responsibility for quality, with the aim of getting the product right first time throughout the organisation.

  3. 3

    What is the main weakness of relying on inspection at the end of the production line?

    Model answer

    Defective items have already consumed materials and labour by the time they are found, so the cost of the fault is incurred whether or not the item is sold.

  4. 4

    How does quality assurance reduce a firm's costs?

    Model answer

    Fewer defective units are produced, so less material and labour are wasted and there are fewer returns, repairs and warranty claims.

  5. 5

    What is meant by getting it right first time?

    Model answer

    It means designing the process so that the product meets the standard at every stage, rather than correcting faults after they occur.

  6. 6

    Why does Total Quality Management require a change in corporate culture?

    Model answer

    Responsibility for quality moves from an inspection department to every worker, which only works if staff are trained, trusted and willing to halt production.
