According to the Professional in Business Analysis (PMI-PBA)® Examination Content Outline, one of the tasks of a business analyst is to “manage stakeholder collaboration to achieve project objectives” (Task 4.1). This includes “facilitating conflict resolution” and “addressing issues that may impact stakeholder relationships” (Task 4.1.3 and 4.1.4). Therefore, the project manager should explain the impact of the scenario to the project team member and help them understand how their behavior is affecting the project and the client relationship. This is also consistent with the PMI Code of Ethics and Professional Conduct, which states that project managers should “respect the property rights of others” and “act in a manner that is in the best interests of society and the environment” (Section 4.3.1 and 4.3.2). References:
