Part 3 BIA Questionnaires: Impact Over Time Of Business Functions

Business Function

Name of business function.
State a name or identifier (of up to 3 words).
Cross-reference to the business function from original business function assigned in Part 1

The acronym for each business function and its serial number.
This function number is used as a shorter form of unique identification of each business function within the entire BIA exercise and also as a cross-reference to the rest of the document.
For example, “HR” is the acronym for Human Resource Department and say, the function is "Payroll". The function number “HR-01” is CBF Number 01 (first of the series of business function) for HR Department.
Cross-reference to the function code from original function code assigned in Part 1

Highest-Impact Area refers to the impact area determined during Impact analysis in part 2 of the BIA

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.

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.
