Quality Control Glossary for Level 3 QA/QC Training

Purpose:

To help learners compile and understand essential QC terminology, its definitions, andpractical applications in UK engineering and manufacturing workplaces. This ensurescorrect usage of terms and alignment with UK laws and standards.

Key Terminology for Glossary-Building

Learner Task

Instructions:

ISO 9001:20151. Review the glossary table above.

  1. Expand it by adding at least 5 additional QC terms relevant to your workplace (civil engineering or manufacturing). For each:
    • Write a clear definition.
    • Provide a UK workplace example of its application.
    • Identify the relevant UK law or standard.
  2. Select three terms from your glossary and write a short paragraph (50–70 words each) explaining how understanding and applying these terms helps maintain quality, ensure compliance, and improve efficiency in UK engineering projects.
  3. Optionally, create a visual mind map linking all glossary terms to their practical workplace application
