Using the results from BIA Questionnaire for calculating MTPD

I've received this question:    In the following example on BIA, MTPD   2 hrs 4 hrs 24 hrs 48 hrs 1 week 2 weeks a. Impact on people, health & safety 1 1 1 1 2 3 b. Impact on environment 1 1 2 3 3 3 c. Impact on reputation 1 1 1 2 2 3 d. Impact on service performance delivery 1 1 2 2 3 4 e. Business impact 1 1 2 2 3 4    1= marginal impact, 2=acceptable impact, 3=high impact, 4=catastrophic impact MTPD = 36 hours (?) – this will be used to work on RTO with consideration also on dependencies. What about the rest of the MTPD under the other items, a, c, d, e?  Are they taken into consideration with the overall MTPD?   Answer: Yes, judging from this BIA Questionnaire, MTPD for this activity will be between 24 hours and 48 hours because in question b. this is where the assessment "3" has appeared for the first time. Whether it will be closer to 24 hours or closer to 48 hours is a matter of discussion with the responsible person from this activity.  The rest of the answers (a, c, d and e) are not relevant because they are not so time critical - you always have to take the answers that are the most time critical.
