A method and system for assessing whether adjustment factors used in a process for testing or monitoring an operational system need to be updated or changed, as well as changing and updating these adjustment factors if needed or desired. At least one current adjustment factor is selected, along with the relevant data. The relevant data is then analyzed to generate results that are collected so that a determination can be made as to whether the current adjustment factor(s) needs to be changed. If it is determined that the current adjustment factor(s) needs to be changed, an updated adjustment factor(s) is provided to replace it. Preferably, the updated adjustment factor(s) is validated before incorporating it into the testing or monitoring process.
