.3 Stakeholder Communication Needs
The business analyst evaluates:
• what needs to be communicated,
• what is the appropriate delivery method (written or verbal),
• who the appropriate audience is,
• when communication should occur,
• frequency of communication,
• geographic location of stakeholders who will receive communications,
• level of detail appropriate for the communication and stakeholder, and
• level of formality of communications.
Communication considerations can be documented in the form of a stakeholder
communication plan. Business analysts build and review communication plans
with stakeholders to ensure their communication requirements and expectations
are met.
