Exam CBAP topic 1 question 425 discussion

A company with a big information technology (IT) department has hired a lead business analyst (BA) to enhance its business analysis practices. The lead BA discovers that sponsors are not satisfied with project outcomes. Developers complain about incomplete, ambiguous, and changing requirements. All stakeholders, including project managers, are blaming long cycles of analysis for the delays. The business analysts, in turn, feel overwhelmed with the number of projects and frustrated by the lack of collaboration from reviewers of their deliverables. All of the evidence is anecdotal and none of the groups could strongly substantiate their options.
The lead BA wants the BAs to report anticipated and actual completion dates for their deliverables, as well as the time spent on planned and unplanned activities.
What is the lead BA trying to do by analyzing the results of such measurements?
