A simple tool for when you want to calculate the upper control limit of your process dataset. The upper and lower control limits are critical indicators to help you determine whether variation in your process is stable and caused by an expected source.The control limits of your control chart represent your process variation and help indicate when your process is out of control. Control limits are the horizontal lines above and below the center line that are used to judge whether a process is out of control. The upper and lower control limits are based on the random variation in the process.Navigating the world of healthcare can be overwhelming, especially when it comes to understanding Medicaid income limits.
