Statistical Process Control统计过程控制
Statistical process control is a quality method that uses control charts and statistical measures to monitor a process, distinguish common-cause variation from special-cause variation, and signal when a process may be drifting out of control. Quality plans, control plans, process capability studies, and shop-floor monitoring procedures describe how SPC is applied so that data-driven decisions guide process adjustments rather than after-the-fact inspection.

Where this term appears
In localization, statistical process control appears in quality software, control plan templates, training materials, and customer audit documentation. Translators encounter terms like 'SPC chart,' 'control limits,' 'out-of-control action plan,' and 'process capability index.' The term must remain stable across documents because SPC concepts are precise; a loose translation can confuse whether the text refers to process monitoring or product inspection.
Translation checks
A common error is translating statistical process control as 'statistical quality control' without recognizing that SPC focuses on process behavior rather than sampling inspection. Another is rendering control chart terms inconsistently, such as mixing 'control limits' with 'specification limits.' These errors can undermine training content and audit responses, especially when statistical terms carry specific meaning in quality engineering.

Check the distinction in context
Control limits and specification limits serve different purposes. Preserve their Chinese labels and chart references. An out-of-control signal should not be translated automatically as an out-of-specification product or a final disposition decision.
Check the returned Chinese file
Inspect the Chinese chart legend and associated instruction together. Retain different labels for control and specification boundaries, and query a source sentence that treats them as equivalent rather than repairing the statistical conclusion.
Prepare the connected files
Send the chart legend and relevant procedure wording. Keep statistical interpretation with the technical owner while terminology is checked across the set.
Keep the term aligned across your files
Check equipment names, units, safety instructions and interface labels against the source and approved references. Confirm any market-specific document requirements separately.
Provide approved terms and previous translations with the source files. Agree how variants, ambiguous wording and revisions will be reviewed. Terminology maintenance and any termbase handback are confirmed in the project scope. See the 8-step AI + expert workflow.
