Thank you for your reply. This is a difficult thread for me. Going further with the example of the same activity:
The activity let's assume is about development, maintenance and debugging for system x
MAO time for an activity is 24 hours.
RTO time is 12h.
Resources needed for restoration are: 3 people, 1 key system, telecommunication links.
The basic assumption for the location is hybrid work by default and office work as an alternative. The hardware will be purchased after the loss and the system is backed up in an alternative server room.
Using the Employees resource as an example:
1. In the case of an office related failure - the situation is unchanged, the interruption of operation has not occurred.
2. in case of failure of the system x - suppose it needs these workers to repair it (they are also responsible for its maintenance), the scheduled time for error verification is 1 hour, 8 hours takes the procedure to run the backup, 1 hour testing after the backup. A total of 10 hours. Then it needs the resource after 2 hours max to maintain the RTO time.
3. in the situation of failure of telecommunication lines necessary for remote work - needs employees to 10 hours in the office to provide them with 2 hours to check the configuration, start up computers, etc.
What resource availability time should I enter in this case. The time depends on the type of disruption and the strategy adopted. With the increase in the number of resources, increases the difficulty of determining the time of availability.
On the basis of the sent example, will it be correct to assume the availability time of the resource as 2 hours and add in additional information message, which results in this time, will be ok?
Or is the assumption of the form different? The instructional video went through this thread, I feel, very quickly, and this is in my opinion a very important assumption.
I've seen BIA analyses where resource availability times were dropped, but I wouldn't want to do that if I can confirm that I know how to use the tool accurately. Best regards
