When sample measurements fall inside the control limits, it means that the process is in control, as there is no other pattern in the samples. This is the basis of Statistical Process Control (SPC), where these control limits are used to monitor and control processes. It does not necessarily mean that each unit manufactured is good enough to sell or that the process output exceeds the requirements, but it indicates that the process is stable and predictable within the control limits.
