Definition
A tool system that reduces external defects by driving down internal defects and containing them immediately, building a quality-first operating culture and lowering warranty cost.
In detail
Quality System Basics (QSB) is a set of tools that reduces external defects by decreasing internal defects and implementing immediate containment, fostering a quality-first culture. It addresses source control of quality issues, preventing defects from escaping. Unlike Total Quality Management, QSB emphasizes rapid on-site response. Its outputs include quality metrics, containment reports, etc., used for continuous improvement and often combined with reliability systems.
Example in practice
When a factory discovers batch defects on the production line, QSB is used for containment. For example, immediately stopping production, isolating defective products, and analyzing root causes. Through QSB's immediate containment, defects are prevented from reaching customers, reducing external complaints. Simultaneously, the team develops corrective actions to prevent recurrence. QSB helps the factory build a quality culture and reduce warranty costs.
