People first. Project teams are about people. It sounds simple enough, but it is rare for leaders and organizations to think like this. Focus on creating a sense of appreciation and inclusion for team members. Let them know they have an opportunity to do and be part of something special.
At the start of a project, take time to acknowledge and introduce all of the team members. Ask them to discuss what they most appreciate about the opportunity to work on the assignment. A short gratitude activity like that can have a powerful impact by reminding team members about the benefits of the journey they are beginning. These conversations also allow team members to identify shared experiences and build rapport quickly.
