The project manager should use synchronous communication methods if they prefer to have immediate contact with team members. Synchronous communication is a type of communication that occurs in real time and allows for faster response times and more interactive discussions. Examples of synchronous communication methods include phone calls, video conferences, instant messaging, and face-to-face meetings. Synchronous communication can help to build rapport, clarify doubts, and resolve issues quickly among team members.
