Section 3.3.2
Principles of Agile Business Analysis: This section highlights the principle
"Welcome changing requirements

Section 5.2.3
Feedback: "Agile approaches use frequent feedback loops to confirm a shared understanding of the need and of the solution that is emerging." The question implies a need for more frequent feedback to process new information
which additional review sessions provide.
Section 7.4
Decision Making: This section discusses the importance of making timely decisions to avoid delaying the team. Facilitating more frequent stakeholder sessions is a key technique to enable this.
