A business owner has identified a high priority requirement that needs to be implemented immediately.

The BA should consider the number of systems being affected by the requirement when performing an impact analysis of this change. This is because an impact analysis is a technique that involves assessing the potential effects of a change on the existing or proposed solution, business processes, stakeholders, or organization. The number of systems being affected by the requirement is an important factor that can influence the feasibility, cost, risk, and complexity of implementing the change. The other options are not as relevant or significant as considering the number of systems being affected by the requirement. References:
