Identifying the stakeholders early on in the business analysis duties helps the business analyst to understand the needs, expectations, and interests of the stakeholders, as well as their influence and authority on the project. This helps the business analyst to plan and manage the requirements activities, communicate effectively with the stakeholders, and address any issues or conflicts that may arise. By involving the stakeholders throughout the business analysis process, the business analyst can ensure that the requirements deliverables are aligned with the stakeholder needs and expectations, and that they are delivered on time and within budget. References:
