There are a number of things the PM can and cannot do when it comes to dealing with team members that have diverted their time and efforts away from the project. The obvious first course of action is to have a sit down with the associate and professionally discuss the concern. If this does not resolve the situation, it may be worth bringing it up to the associate’s manager. Whether the distractions are due to personal or professional non-project related factors, the associate and his or her manager should be able to re-establish priorities so that the deliverables for the project can be made on time. Worst case scenario, another employee may be needed to join the project team to support where there is a lack of results. This is actually something I experienced in a team I am a part of this week.
