Maximum Allowable Outage and non financial impact

Answer: You can have situations where the non financial impact is high and the financial impact is low, so the non financial impact is more significant to determine the MAO. In such cases the MAO is not calculated, but determined considering the perceptions of the interested parties about how much time the outage should last so the organization wouldn't be able to resume business activities. Since this is a subjective approach, you should involve personnel with as much as experience and knowledge about the impact as possible, to ensure some degree of confidence in the MAO value.
