About Custom Line

After you have drawn the Demonstrated Line, the Process Reliability Line, and the Nameplate Line, you can optionally draw one or more additional Custom Lines to compare historical or projected production rates to the observed production rate. For example, you might draw a Custom Line:

To compare the current year's production to the previous year's production.
To compare your company's production rates with the production rates of another company that is using the same process.
To project how much more you could produce the next year if you improved your process to achieve a projected production rate.
