Statistical Process Control(SPC)

In order to deliver effective and repeatable quality control, many companies choose to use statistical process control (SPC) software, which tracks the data that comes off manufacturing lines and alerts machine operators and plant supervisors to potential problems.


In manufacturing, statistical process control (often associated with overall equipment effectiveness, or OEE) describes the process of collecting quality control data for statistical analysis. The collection of this data allows manufacturers to identify any quality concerns that need to be addressed before they escalate into expensive problems.

Statistical process control can be applied to individual components or end-products to ensure they perform within specified parameters. SPC can also be applied to manufacturing tools and machines themselves to optimize machine output. This helps reduce scrap rates and the number of components that need to be checked and replaced during the maintenance cycle, lowering the chance of machine failure and unscheduled downtime.


SPC software facilitates statistical process control by collecting data in real-time and alerting the manufacturer to any results that fall outside the accepted range. This, in turn, helps reduce process variation, improves manufacturing efficiency and lowers overall production costs.
