Zero Defects is a concept used across lean production to describe: A quality philosophy that aims to prevent defects rather than detect or correct them later. It emphasizes doing the work correctly the first time, every time, and building quality into every process. It is one of the vocabulary items that operators, team leaders and continuous-improvement engineers rely on daily to describe how work flows through a factory.
Shared vocabulary is what makes lean transformations move. When everyone on the floor uses "Zero Defects" the same way, teams can spot problems, design experiments and improve processes without translation loss. That common language is a small thing that quietly makes every other improvement effort faster.
The principle of designing equipment to stop automatically and to detect and address problems immediately.
Techniques designed to prevent errors by making it impossible to perform a task incorrectly.
A process of 'continuous improvement' to ensure maximum quality, eliminate waste, and improve efficiency.
The documented best-known method for safely performing a task using the correct sequence, timing and inventory.
A root cause analysis technique used to identify the underlying cause of a problem by repeatedly asking “Why?” until the fundamental issue is discovered. Rather than treating symptoms, the method helps reveal the true source of the problem and supports effective, long-term corrective actions.
The percentage of products that pass through a process correctly without requiring rework.
A Japanese lean concept meaning "self-study" or "self-directed improvement." It is a hands-on improvement activity that involves a cross-functional team.
