Quality Management Approaches

🔍
Quality Control (QC)

Inspection and testing AFTER production to identify and reject defects.

  • Reactive approach—detects problems after they occur
  • Sample testing or 100% inspection
  • Defects are reworked or scrapped
  • Cost: Waste, rework, possible recalls

✓ Pros

  • Simple to implement
  • Lower initial cost
  • Catches major defects

✗ Cons

  • Costly rework/waste
  • Reactive, not preventive
  • Reputation risk
🛡️
Quality Assurance (QA)

Prevention systems built into production to maintain quality standards DURING manufacturing.

  • Proactive approach—prevents defects before they happen
  • Standardised processes and procedures
  • Staff training and clear specifications
  • Monitoring at each production stage

✓ Pros

  • Reduces waste & rework
  • Consistent quality
  • Improves reputation

✗ Cons

  • Higher upfront cost
  • Requires training
  • More complex systems

Additional Quality Philosophies

Total Quality Management (TQM)

Continuous improvement culture where ALL employees are responsible for quality. Aims for zero defects. Involves benchmarking against competitors and Kaizen (continuous small improvements).

Lean Production

Eliminates all waste (muda) from production while maintaining quality. Just-In-Time ordering, flexible workforce, minimal inventory. Associated with Japanese manufacturing.
