I recently created a simple tool to help me effectively calculate the Availability, Reliability and Maintainability of I.T. Services. I find that such tools offer some helpful objectivity to the often chaotic world of Non-profit organizational management I work in. I hope that this tool helps people learn and apply these simple disciplines to their own I.T. management processes.
The tool itself is just an Excel spreadsheet that contains ITILv3 Availability Management formulas. I like to manage I.T. Availability down to the second. But you can change to tool to fit your needs.
Hopefully the tool is self explanatory. Just let me know if you have any questions.
