When sample measurements fall inside the control limits, it indicates that the process is in control, meaning that the process is predictable and stable. It does not necessarily mean that every unit manufactured is good enough to sell or that the process output exceeds the requirements. Additionally, it does not imply that the process output fulfills the requirements. Control limits are determined statistically based on process data, and falling within those limits indicates that the process is operating within the expected range.
