Definition
The set of procedures and standards used by an organization to ensure that a product or service meets specific requirements and is free from defects.
Why It Matters
Quality control is the primary defense against “systemic rot.” Without it, a $4 part can destroy a $60 million rocket. It is the practice of universal verification that acknowledges that the most complex machine is still only as reliable as its weakest, least-inspected link, and that the cost of failure far outweighs the cost of inspection.
Core Concepts
- Inspection: Physical checking of parts or products against a specification.
- Process Control: Monitoring the manufacturing process itself to prevent defects.
- Factor of Safety: Designing a system to handle loads higher than operational loads.
- Root Cause Analysis: Identifying the fundamental reason for a failure.
