Cost of Outages calculations
To calculate the information displayed in the graphs, the ROI flashboard uses data gathered from the user (by way of the flashboard interface) as well as from the various configured parameters.
The formulas used by these calculations are described in the following table.
The values used in the formulas are:
- A = Cost (per minute)
- B = Monthly Outages (in minutes)
- C = Number of months calculated by the system, based on user input
Although the user can enter a date range that includes a day of the month, the day of the month is ignored and only the month and the year are considered. For the purposes of the system calculations, Start Date is always assumed to be the first day of the selected month and year, and the End Date is always assumed to be the last day of the selected month and year. For example, if the user entered May 21, 2009, as the Start Date, and July 10, 2009, as the End date, the system uses May 1, 2009, as the start date and July 31, 2009, as the end date.
- G = The total amount of outages during the date range specified by the user (calculated by the system).
H = The estimated number of minutes lost to outages on a monthly basis that is used by your organization for creating baseline estimates.
Cost of Outages flashboard calculations
Baseline Cost of Outages (ProjCstO)
A x B = ProjCstO
Actual Cost of Outages (ActCstO)
The formula used to calculate the actual cost of outages depends on the parameter that you select in Outages Input.
- Specify Estimated Outage
A x H x C = ActCstO
- Calculate Resolution Time
A x H = ActCstO
- Calculate Cumulative Outage
A x G = ActCstO
