Control charts play a crucial role in detecting whether a process is in-control or out-of-control. The standard Shewhart-type control charts (Shewhart, 1931) are based on inspecting samples at equally spaced time intervals and issuing an alarm (a signal) if the “result of the sample” is considerably worse (i.e. larger or smaller) than what one can expect if the process was operating on target. In this article we construct the non- parametric control limits for mean based on grouped signed rank with process capability for the data on balance with the presently available control limits.
