I think the best strategy is to get the disagreeing parties together in a room and have a face to face meeting so that everyone can understand the full picture and determine a strategy for moving forward. A very important thing for a project manager to remember is to avoid finger pointing and try to reduce finger pointing among team members, as this does not help the project at all and causes hard feelings. If the project manager had tried to resolve this by talking separately with Patty and Malekai it would have been much more leg work for the project manager, and could have resulted in additional misunderstanding, whereas in the simulation, once Patty, Malekai and the project manager sat down together to discuss the issue with the animal study timeline, although Patty was not happy with the outcome, she understands why the animal studies are need to take so long and accepts the timeline.
