A project manager is in a team meeting and the project team requires a decision to be made about a new suggested timeline due to an impact from a potential scope change. What should the project manager do?

This option is not advisable as it bypasses the collaborative nature of project management and could alienate team members and stakeholders. Making unilateral decisions can lead to dissatisfaction and resistance, undermining the project's success and stakeholder relationships.

While involving stakeholders is important, simply scheduling a meeting may not be efficient or necessary if the stakeholder engagement plan already provides a clear path for decision-making. This approach could also delay the timeline unnecessarily if a decision can be made following established protocols.

Delegating the decision to the most senior person may not align with the collaborative spirit required in project management. It risks sidelining other important stakeholder inputs, which can lead to decisions that do not reflect the collective understanding and needs of the project team.
