The project sponsor receives updates promptly but is concerned that reports lack key information. What should the project manager do?

The project manager should review the communication needs of key stakeholders, including the sponsor, to ensure that reports contain the necessary information. This proactive step involves understanding what specific data points, level of detail, and format the sponsor requires to feel adequately informed. Verifying sponsor understanding and providing feedback opportunities are good practices but don't address the root cause of missing information. Defining communication methods, frequency, and level of detail is part of the solution, but it's a step that follows understanding the needs. Providing all available project information would likely overwhelm the sponsor and still might not contain the key information they are looking for, making it inefficient and potentially counterproductive.
