According to the PMBOK® Guide, the Monitor Communications process (referred to in earlier versions as Control Communications) is the process of ensuring the information needs of the project and its stakeholders are met.

Work Performance Information (WPI): This is a primary output. It involves taking the raw work performance data collected during execution and comparing it against the communications management plan. For example, it might include data on the effectiveness of communication activities, such as whether stakeholders are receiving and understanding the reports as planned.

Change Requests: If the monitoring process identifies that the current communication strategy is ineffective—perhaps a stakeholder is not receiving critical updates or the chosen medium is causing delays—the project manager will issue a change request. This could lead to updates in the Communications Management Plan or other components of the Project Management Plan.

Other Outputs: These include updates to the Project Management Plan (specifically the Communications Management Plan and Stakeholder Engagement Plan) and updates to Project Documents (such as the Issue Log and Stakeholder Register).

Comparison with other options:

A. Expert judgment: This is a Tool and Technique used to assess the communication requirements and the influence of stakeholders, not an output.

C. Project management plan updates and work performance information: While both are technically outputs, the standard pair often emphasized in PMI examinations for the " Control " or " Monitor " phase of any knowledge area is the generation of Work Performance Information and the resulting Change Requests.

D. Issue logs and organizational process assets updates: These are Project Document Updates and OPA Updates, respectively. While they can occur, they are secondary to the primary functional outputs of WPI and Change Requests that drive the project ' s corrective actions.
