Software Incident Mean Time to Recovery (MTTR) Calculator computes Mean Time to Recovery per incident in s using the defined engineering formula and the input values provided. Mean Time to Recovery per incident is expressed in s. No universal acceptance threshold is defined by this calculator.
Worked Example
Verified calculation
Given:
- Total cumulative recovery time across all incidents = 3600
- Number of resolved incidents in measurement period = 4
Expected Result:
- Mean Time to Recovery per incident = 900
Engineering Interpretation:
Under the given input conditions, the calculated result is: Mean Time to Recovery per incident = 900 s.
The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.
Formula / Method
mean time to recovery per incident = total cumulative recovery time across all incidents / number of resolved incidents in measurement periodMean Time to Recovery per incident.
