 A business analysis communication plan is a document that describes how the business analyst will communicate with the stakeholders, including the stakeholder groups, communication needs, level of formality, frequency, format, and methods of communication. It is one of the outputs of the business analysis planning and monitoring knowledge area, and it helps to ensure that the stakeholders are informed, engaged, and satisfied with the business analysis process and deliverables. A business analysis communication plan is not the same as a project communication plan, which covers the overall communication needs of the project and is typically created by the project manager. A business analysis communication plan focuses on the specific communication needs related to the business analysis activities and requirements. References:
