Correct Answer: BCTo expedite the approval process for the analysis phase, the business analyst should focus on the business analysis information architecture. This is because the architecture helps ensure that the complete set of requirements is properly organized and related. It defines and verifies the relationships among various types of business analysis information, such as requirements, designs, and elicitation results, ensuring the requirements package is comprehensive and cohesive. This thoroughness helps facilitate stakeholder understanding and decision-making, thereby speeding up the approval process.
