      Quality assurance when manufacturing: communal areas

      Lesson details

      Learning outcome

      I can manufacture accurately and to a high quality.

      Key learning points

      1. Designers and manufacturers use quality assurance (QA) and quality control (QC).
      2. Quality assurance is about checking the planning and processes.
      3. Quality control is about checking the product to make sure it meets the required standard.
      4. When QA and QC checks take place, they are ensuring accuracy.

      Keywords

      • Manufacture - the process of making products from raw materials using machines or labour

      • Quality assurance - ensuring the production process prevents mistakes and maintains quality

      • Quality control - checks made on a product before, during and after its production so it meets quality and safety standards

      • Accuracy - being correct and precise

      • Tolerance - the acceptable range of variation in a product's dimensions

      Common misconception

      Quality control and quality assurance is the same thing.

      Quality control focuses on identifying defects in finished products, while quality assurance is about preventing defects through planned processes and systems during production.

      Teacher tip

      Defining the difference between these two areas will be the key point of this lesson as these are so often muddled or misunderstood.
