Working in a team can be quite challenging. Deciding what to agree on for an outcome or goal is important for the success of a project. Some key actions to evaluate solutions and gain consensus on the decision to be implemented are:

1. Describe the decision and how it will be made.
2. Jointly establish decision-making guidelines.
3. Jointly evaluate options against the guidelines.
4. Gain agreement on the best alternative.

Keep it cool, civilized, and concise. Keep discussions on topic and on time. Most of all, communicate well!
