According to the PMBOK Guide, 6th edition, one of the key processes of the Project Communications Management knowledge area is Plan Communications Management, which involves determining the information and communication needs of the project stakeholders. One of the tools and techniques for this process is communication requirements analysis, which considers factors such as the availability, frequency, format, and level of detail of the information. By asking the project sponsor what sort of information is needed and agreeing on a frequency for the communication, the project manager is performing communication requirements analysis, which will help to tailor the communications management plan to the specific needs and preferences of the project sponsor.
