As mentioned, the privilege of picking one’s ideal team is not always an option. If one does have a choice though, knowledge in the department is more important than the relationship. Having a good relationship is beneficial for good communication and compromising but it is only a bonus to being a good knowledgeable worker. If a team member does not get a long with the project manager, but does know their department very well, they should always be able to act professionally and work around it for the time being. On the other hand, if a team member has a good relationship but is not knowledgeable, the project can be delayed.
