Selecting and Alternate Site would not be done within the initial BIA. It would be done at a later stage of the BCP and DRP recovery effort. All of the other choices were steps that would be conducted during the BIA. See below the list of steps that would be done during the BIA.
A BIA (business impact analysis ) is considered a functional analysis, in which a team collects data through interviews and documentary sources; documents business functions, activities, and transactions ; develops a hierarchy of business functions; and finally applies a classification scheme to indicate each individual function’s criticality level.
BIA Steps
1. Select individuals to interview for data gathering.
2. Create data-gathering techniques (surveys, questionnaires, qualitative and quantitative approaches).
3. Identify the company’s critical business functions.
4. Identify the resources these functions depend upon.
5. Calculate how long these functions can survive without these resources.
6. Identify vulnerabilities and threats to these functions.
7. Calculate the risk for each different business function.
8. Document findings and report them to management.
