Explanation
According to the PMBOK Guide, 6th edition, page 368, communication can be classified into formal and informal, written and verbal, and vertical and horizontal, depending on the context, purpose, and audience of the message. Informal verbal communication, such as a conversation, is a type of communication that is spontaneous, casual, and flexible, and that can be used to exchange information, ideas, opinions, or feedback in a timely and direct manner. Informal verbal communication is suitable for handling a situation where a team member is not performing very well, as it can allow the project lead to express concern, empathy, and support, as well as to identify the root causes of the poor performance, and to explore possible solutions or improvements. Informal verbal communication can also help to maintain a positive and trusting relationship between the project lead and the team member, and to avoid any misunderstanding, resentment, or demotivation that may arise from more formal or written communication.
