According to the BABOK Guide, Version 3.0, the business analysis approach is the set of processes, activities, techniques, deliverables, and roles that are tailored to suit the specific needs and context of a change initiative1. The business analysis approach should be defined in collaboration with the key stakeholders, such as the project manager, the sponsor, the solution owner, and the subject matter experts2. Working with the appropriate stakeholders to determine how the business analysis work should be completed is the best action to take to begin business analysis, as it ensures that the approach is aligned with the project objectives, scope, constraints, and stakeholder expectations3.
