3. Team Norms/Values Team Meetings and Punctuality: Details of team meetings will be expected to be maintained on the edge website starting the second week of senior design I. Individual members are required to notify the project leader along with other members in the event a meeting cannot be made. It is understood that all members are expected to be punctual. In the event that members frequently miss team meetings or are late, consequences will be discussed with the remainder of the group. Informing the course guides will remain a viable option. Assignments and Deliverables: Any assignments or deliverables are to be assigned as evenly as possible among group members. The agenda of deliverables and who they are assigned to is to be updated during all meetings. All work submitted is expected to comply with the academic honesty policy. This policy is easily available on campus thus is beyond the scope of this section. All assignments are expected to be done on time and on schedule. In the event that completion is either unlikely or known to be unlikely, those assigned the task must promptly inform all other group members. A certain degree of unexpected obstacles should be allowed for during the quarter.

4. Team Norms/Values Idea Generation and Decision Making: Any and all ideas are valid through the course of this design project. Special effort will be placed on ensuring every member has a voice and is contributing to the process. It is also very important that decisions and direction or made by the team as a whole. The typical raise of hands voting system along with silent voting will be used whenever necessary. Efficient work for the team requires many diverse ideas along with concrete direction. Peer Assessment: Peer assessments will be done on Fridays informally at the very least. Members of the group can discuss and all concerns during this time with their peers. Focus will placed on constructive criticism and balancing work load.
