According to the BABOK^® v3 guide, the purpose of the task: Communicate Business Analysis Information is as follows:

A key success factor in effectively managing business analysis information is that the information is communicated at the right time and in formats digestible and relevant to the intended stakeholder audience. It is therefore also important that the business analyst pays attention to the tone, style, and language used when deciding to communicate business analysis information to a particular stakeholder audience.

When the business analyst communicates information to stakeholders, it is important to understand that this process is iterative and interactive, meaning the information and feedback flows between the business analysts and the stakeholders in a two-way communication format. The business analyst should, therefore, be clear about the audience that business analysis information is being shared with, and be equally clear on the content, purpose, context, and what the business analyst is expecting to receive as a result of the business analysis information sharing.

It is important to remember that it might be required for the business analyst to distill information in multiple ways to cater to different audience communication styles. It is also important that the business analyst works with stakeholders to ensure that they provide their agreement that the information is accurate and relevant to the purpose of what the delivery is working toward.

Example of communicating business analysis information

In a practical example, you will have a set of draft requirements that you elicited from a group of stakeholders during your recent requirements workshop. As a first step of communicating your findings, you may send out an email with the draft requirements available for review. You know that some of your stakeholders don't really respond to or read detailed emails and therefore decide to follow up the message with an invitation for a short meeting to walk them through the details of the requirements. 

By providing the stakeholders with these two different opportunities to review and understand your requirements, you are optimizing communication with your stakeholder audience.
