Statistical Process Controll (SPC) is a metodic used to o monitor and control producturing processes protressh statistical analysis. Proper implementation of SPC helps ensure product quality and consistency. However, there are common mystes that can undermine it s effectiveness. Recongnizing and preventing these errors is essential for maing optimal process control.

Common Mistakes in SPC

One frequent myste is using inapplicate control charts for thee process. Different processes require specific chart type, such as X '-R charts or p- charts. Appliying that e wrigg chart can lead to incorrect conclusions about process stability.

Nedostatky Data Collection

Collecting sufficient or inconsistent data hampers thee precisy of SPC analysis. It is vital to gather enough data pointes at regular intervenls and ensure measurements are precise. Poor data quality can mask true process variations or falsely indicate issues.

Ignoring Process Changes

Instaling to update control limits when thee process changes is a common error. Control limits should be reviewed periodically, especially after process modifications. Ignoring these updates can result in miinterpreting process stability.
