Team Values and Norms

Members of the ‘SpringBrakers’ MSD Team agree to the values and norms listed below. Team members will use these to assess one another in Peer Reviews.

Punctual

Each team member will be prompt and arrive at the team meetings on time. If an unexpected conflict comes up, the absent team member will notify at least one teammate prior to the expected absence. An absent team member should confirm that a teammate has received their message (in person, voice mail, email).

Thorough

Each team member will complete his or her tasks thoroughly and completely, so that the team does not have to do work for member. If a member does not know how to complete a task, feels overwhelmed, or needs assistance then the member notifies peers, and seeks assistance from a peer, the faculty guide, a faculty consultant, or another person.

Accurate

Each team member completes their work accurately and in a way that peers can easily check for accuracy by peers and the faculty guide. All work is fully documented and easy to follow.

Professional and Ethical

Each team member gives credit where credit is due. All work completed includes citations to appropriate literature, or sources of assistance. If a team member has gotten assistance from a publication or individual, then that assistance or guidance is fully documented in the reports prepared. All team members are honest and trustworthy in their dealings with their peers.

Committed

Each team member will contribute an equal share to the success of the project.

Respectful

Team members will be courteous of the work, effort, and time spent by the team. Proposed ideas and concepts will be fairly reviewed without personal influence.
