"On any large project or working as part of a larger team, a true team effort is a must. Every person involved has a specific role to play. If a team member wasn't doing the necessary work or giving the necessary information, as a leader, I would first approach them directly in a one-on-one situation to reset my expectations for them as part of the team. I wouldn't place blame. I would listen to them and absorb what they were saying to me. Ultimately, I would stay positive. I'd stress just how critical their involvement in this team was, and that the team goes as the people driving it goes. If they lacked support in some way, then we would resolve that issue together."
