Subject: SAP Quality Management (QM)
In quality management, monitoring and controlling process performance is crucial to ensure consistent product quality. Control charts are vital statistical tools used to track process variation over time and detect any signs of instability. In SAP Quality Management (QM), control charts help analyze inspection data to maintain control over production and service processes.
This article explains the concepts of control charts for variables and attributes, their application in SAP QM, and their significance in quality control.
A control chart is a graphical tool used to plot data points collected from a process over time against predefined control limits. It helps identify trends, shifts, or unusual variations indicating that a process may be out of control.
Control charts distinguish between:
Variables data are measurable quantities with continuous numeric values, such as length, weight, temperature, or time.
SAP QM supports control charts for variables by integrating inspection results recorded during quality inspections. These charts allow quality engineers to:
Attributes data are countable and represent qualitative characteristics, such as the number of defects or defectives in a sample.
SAP QM facilitates the creation and evaluation of attribute control charts by capturing defect counts and inspection lot data. This helps:
Control charts for variables and attributes are indispensable tools within SAP Quality Management for ensuring process stability and product quality. By effectively applying these charts, organizations can identify deviations early, reduce defects, and foster a culture of continuous quality improvement.
Leveraging SAP QM’s capabilities to capture and analyze data empowers quality professionals to maintain high standards and achieve operational excellence.
