A business analyst (BA) is tasked with developing a business analysis plan and must decide...

According to the BABOK® Guide1, the business analysis approach is the set of processes, tools, deliverables, techniques, and standards that will be used to perform business analysis work on a project. The approach can be either plan-driven, adaptive, or a hybrid of both. A plan-driven approach is more suitable for projects that have stable and well-defined requirements, low levels of change, and clear acceptance criteria. An adaptive approach is more suitable for projects that have uncertain or evolving requirements, high levels of change, and emergent outcomes. Therefore, one of the factors that would drive the decision towards an adaptive approach is the organization’s tolerance for uncertainty, which means the degree to which the organization is willing to accept ambiguity and risk in the project. An organization with a high tolerance for uncertainty can benefit from an adaptive approach that allows for frequent feedback, experimentation, and learning. References:
