Statistical Process Control (SPC) is a scientific, data-driven methodology for quality and process improvement. It removes guesswork out of quality control.
Statistical Process Control (SPC) is a statistical technique for measuring and controlling product quality. It is applicable for in-coming, in-process and out-going quality control. Quality data in the form of Product or Process measurements are obtained in real-time during measurement. This data is then plotted on a graph with pre-determined control limits. Control limits are determined by the capability of the process, whereas specification limits are determined by customer.
Data that falls within the control limits indicates that process is operating as expected. Any variation within the control limits is likely due to a common cause—the natural variation that is expected as part of the process. If data falls outside of the control limits, this indicates that an assignable cause is likely the source of the product variation, and something within the process should be changed to fix the issue before defects occur.
To quantify the return on your SPC investment, start by identifying the main areas of waste and inefficiency at your facility. Common areas of waste include scrap, rework, over inspection, inefficient data collection, incapable machines and/or processes, paper-based quality systems and inefficient lines.
You can start to quantify the value of an SPC solution by asking the following questions:
