Statistical quality control (SQC) is a method of visually monitoring manufacturing processes. With the use of control charts and collecting few but frequent samples, this method can effectively detect changes in the process that may affect its quality. ProFicient provides crucial statistical quality control analysis tools that support SPC for long- and short-run SPC applications and for both attribute and variable data types. Choose from hundreds of different quality control charts to easily manage the specific challenges of your SPC deployment. Control Chart A control chart is a time plot of a statistic, such as a sample mean, range, standard deviation, or proportion, with a center line and upper and lower control limits . The limits give the desired range of values for the statistic. Pareto Charts Cause and Effect Diagrams Defect Concentration Diagrams Scatter Diagrams Control Charts Statistical Quality Control (SQC) Tools of statistical quality control. Several techniques can be used to investigate the product for defects or defective pieces after all processing is complete. Typical tools of SQC are: Basic SPC Tools In statistical control: a process operating with only chance causes of variation Out of control: a process operating in the presence of assignable causes A control chart contains A center line An upper control limit A lower control limit A point that plots within the control limits indicates the process is in control A point that
6 Jun 2019 Control charts, the key tools of SPC, use control limits to monitor the performance of a process over time to determine whether special variation Once the control limits have been established of the X-bar and R charts, these limits may be used to monitor the mean and variation of the process going forward.
