PURPOSE OF THE UNIT STANDARD 
This unit standard is required by people working in the manufacturing environment. They need to understand and apply the principles of JIT and lean manufacturing and to ensure continuous improvement in the workplace.

Learners credited with this unit standard are able to:
  • Explain Just in Time (JIT) and lean manufacturing.
  • Discuss the principles of flow shop manufacturing operations.
  • Explain waste and waste elimination in a manufacturing environment.
  • Explain the concept of the theory of constraints.
  • Implement continuous improvement. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
  • Mathematical Literacy at NQF Level 2.
  • Communication at NQF Level 2. 

  • UNIT STANDARD RANGE 
    Specific range statements are provided in the body of the unit standard where they apply to particular outcomes or assessments.
