Part 3: Impact Over Time of Business Functions
Business Function and Function Code (Col 2 & 3)
- Cross-reference to the Business Function/function code or number from original Function No assigned in Part 1
Highest Impact Area (Col 4)
- Highest-Impact Area refers to the impact area determined during Impact analysis in part 2 of the BIA
Impact Over Time
- The timescale for a business function to be carried out on a normal day. You can consider it as to how long does it takes to do one transaction. Insert the appropriate timescale found in the BIA Questionnaire.
- Example of a typical entry is “1” if the time scale is less than 4 hrs, “2” if less than 1 day. Refer to the scale found in Part 2.
- Sometimes referred to as Disaster Timescale or Crisis Timeline
- During a disaster, would you be able to stretch the timescale during the delivering of this business function? Would your customer be able to bear with the delay?
- Please make a personal judgment based on a “credible” Worst Case Disaster Scenario.
- Could the business function be carried out over a longer period, possibly by using different means during a disaster?
- Assume it is not possible to access your office location.
- Maximum Tolerable Period of Disruption or MTPD/MTPoD is the maximum allowable time that the organization’s key products or services is made unavailable or cannot be delivered before its impact is deemed as unacceptable.
- State the specific time e.g.
- 25th of month
- 4.30 pm daily
- Not applicable
etc. whereby the business function is most vulnerable.
- Notes (1): Try to discourage answers such as “All day” and “Ad-hoc.” Additionally, try to give a definitive date instead of a range. For example, no 5 to 7 days
- Notes (2): The key is to identify how much time it takes to complete a transaction and compare this with the time to be taken during a disaster.
