downtime

It's obvious that downtime is bad for business.

Here are some suggestions for calculating the likely costs of downtime:

* Detail the number of users for each application and the number of hours that they would use it in a normal day.
* Add a rough valuation of the cost per hour for that group.
* Downtime is a major variable in terms of risk and likely cost, so calculate a number of them: 15, 30, 60 minutes; 4, 8, 16, 24, and 48 hours.
