Although the team member was absent, they possess expert knowledge that may impact project outcomes. The appropriate course of action is to schedule a meeting to hear their concerns and determine whether any adjustments are necessary. This aligns with stakeholder engagement best practices and the PMBOK Guide's principle of team collaboration and empowerment.
Option A discourages engagement and feedback.
Option C focuses on compliance rather than collaboration.

The first response should focus on alignment and awareness. The team charter defines the expected behavior and working norms. It is essential to clarify these expectations with the new team member to provide an opportunity for correction before escalation.
PMBOK Guide - Seventh Edition emphasizes the use of the team charter as a primary tool for setting and maintaining team norms and culture.
Option B escalates prematurely.
Option C could follow if the behavior continues.
Option D is reactive and should be used only if alignment efforts fail.

The Stakeholder Register is a critical document in project management that lists all stakeholders involved in a project, including their roles, requirements, expectations, and influence on the project. The fact that the leader of a user party was not included in the requirements collection communications suggests that the Stakeholder Register was either missed or outdated. This document should have been used to identify all parties with a vested interest in the project, ensuring their needs and expectations are considered during the requirements collection phase. An up-to-date Stakeholder Register is essential for effective communication and project success12.
