According to the PMBOK® Guide, specifically within the Project Communications Management knowledge area, effective communication requires a " closed-loop " system to ensure that information is not only sent but also received and understood.

The Feedback Loop: In the scenario described, the communication is " one-way " —one person talks while others listen. This lacks the Feedback component of the Interactive Communication Model. Feedback is the response from the receiver that confirms they have decoded and understood the message.

Addressing Missed Deadlines: When a team is missing deadlines, it often indicates a lack of alignment or misunderstanding of tasks. Without a feedback response, the project manager and the speaker have no way to verify if the instructions were clear or if the team members have the information they need to succeed.

Interactive Communication: Daily meetings (such as Daily Stand-ups in Agile or coordination meetings in Waterfall) are intended to be Interactive Communication. This requires a multi-directional flow of information where participants provide status updates, raise blockers, and confirm their understanding of the day ' s goals.

Why other options are incorrect:

Option A: Interpersonal communication: This is a broad category of communication (face-to-face or virtual interaction). While the team is engaging in interpersonal communication, the specific step missing from their process to ensure effectiveness is the feedback loop.

Option C: Push communication: The scenario actually describes an over-reliance on push communication (sending information to recipients without expecting an immediate response). Adding more push communication would not solve the problem of team members simply listening and not engaging.

Option D: Pull communication: This is used for very large volumes of information or large audiences where recipients access content at their own discretion (e.g., an intranet or a shared drive). It is not appropriate for a daily meeting where immediate synchronization is required.
