Concept Generation Note: Final grading of the team's concepts (based on the info in the design report) will include points for documenting failed attempts (fail often to succeed sooner) and will reward authentic creativity. > A-level work must include the use of creativity-enhancing methods and “customer perspective” activities and result in at least 4 feasible alternatives and at least one unique idea that responds to the need but is not based directly on a customer request or a benchmarked product - a new idea that the customer will appreciate but that he/she hadn't imagined. > B-level work includes the use of creativity-enhancing methods that result in at least 3 feasible alternatives that respond to the need, with some originality of features and approaches. > C-level work is at least 2 feasible alternatives that respond to the need, with only moderate originality of features and approaches. > Unacceptable work means feasibility is not shown, that all ideas are derivative (have been done before) and do not really respond to the need.
