A project team conducts regular standup meetings to keep everyone updated on what each one of them is working on. What type of communication is this?

Informal communication includes unplanned or routine verbal exchanges such as team standup meetings. Standups are not governed by official protocols, do not produce formal documentation, and are held as casual team check-ins, which classifies them as informal under PMI communication frameworks.

Unofficial communication implies communication that is not sanctioned or recognized by the organization, but standups are an established, recognized team practice.

Formal communication refers to structured, documented communication such as official reports, presentations, or written notices that follow organizational protocols.

Hierarchical communication describes the direction of information flow along a management chain, not the formality or format of a meeting type.
