Like all teams, your Capstone team will need to learn how to work together effectively. Fortunately, getting teams to work well effectively is a problem with known solutions. In 1965, Psychologist Bruce Tuckman identified four stages through which teams progress as they learn to become effective: Forming, Storming, Norming, and Performing (see Tuckman's stages of group development on Wikipedia). These stages are described below.
Note that teams must progress through each lower stage to reach a higher stage. If teams don't form, storm, and norm, they never get to the Performing stage. This can cause problems at BYU because we understand that contention is wrong, so we try to be `nice' and avoid sharing our true feelings so as not to raise the level of conflict in the team. Teams that are afraid of conflict may back away as soon as they start to reach Storming, thus remaining permanently in the Forming phase and failing to reach their potential.
It may be helpful to understand that not all conflict is contention. People will have differences of opinion. This is to be celebrated; it means that the team is stronger than any individual on the team. As long as team members are respectful of others with whom they disagree, conflict will not become contention. With respect for other team members, conflicts can be resolved and accommodated as the team moves into the Forming stage. If instead, the team backs away at the first sign of conflict, they never become a high-performing team.
During the transition from Forming to Storming, there is a real possibility for the team to fail by having team members go along with a proposal even if they don't agree with it. Sometimes, even the member who made the proposal is not in favor of it, but the team still moves forward because they value lack of conflict more than they value getting the right solution. It's important that every member feel free to voice their opinions, even if the rest of the team disagrees.
