🔍 Quality control vs quality assurance
Quality control (QC)
Quality control means checking products at the end of the production process to find and remove faulty ones.
- Inspection happens AFTER production
- Faulty products are rejected or fixed
- Simple to implement
- But: waste has already happened — defective items used up resources
Quality assurance (QA)
Quality assurance means building quality into every stage of production, so defects are prevented rather than found.
- Every worker is responsible for quality at their stage
- Standards and processes are set in advance
- Less waste — problems are caught early
- Can lead to certifications (e.g. ISO standards)
QC = catch defects at the end. QA = prevent defects throughout. QA is more proactive! 🛡️
