What is a Control Limit Change Ratio?

A control limit change ratio is a measure used to determine the relative change between an old control limit and a new control limit. This ratio is important in various fields such as quality control, manufacturing, and process management, where maintaining specific control limits is crucial for ensuring product quality and process stability. By calculating the control limit change ratio, one can assess the impact of changes in control limits and make informed decisions to maintain optimal performance.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ R = \frac{120 - 100}{100} = 0.20 \]

The Control Limit Change Ratio is 0.20.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ R = \frac{150 - 100}{100} = 0.50 \]

The Control Limit Change Ratio is 0.50.
