Which of the following best defines "ad hoc meeting"?

An ad hoc meeting is characterized by its purpose-driven nature, meaning it is convened to address a specific issue, situation, or decision requiring immediate attention. This type of meeting is not part of a regular schedule, nor does it follow a predetermined agenda that dictates a routine discussion. Instead, participants gather to provide input and forge solutions for a particular challenge at hand, making the definition of an ad hoc meeting centered around its targeted objective.

In contrast, regularly scheduled discussions are planned in advance and occur at consistent intervals, which does not align with the spontaneity of ad hoc gatherings. Meetings that follow a strict agenda typically imply a structured process with allotted times for various topics, which again distinguishes them from the flexible nature of ad hoc meetings. Finally, conferences held for networking focus on relationship-building rather than on a specific problem-solving agenda, further highlighting the specific and immediate focus that defines ad hoc meetings.
