Correct Answer: AWhen an organization shifts from a waterfall methodology to an agile approach, the timing of business analysis work is most impacted. In a waterfall approach, business analysis tasks are typically performed in a linear and sequential manner at the beginning of the project. Conversely, in an agile approach, business analysis work is iterative and ongoing throughout the project lifecycle. Requirements are continually refined and adjusted, necessitating the business analyst's involvement beyond the initial planning phase. Therefore, the timing of business analysis work is significantly impacted by this methodological change.
