Build the Prototype Rubric

Elements / Weight / 5 Points / 4 Points / 3 Points / 2 Points / 1 – 0 Points / Total
Prototype Concept / Clearly based upon group’s research. Ease of construction, operation, and maintenance are incorporated into prototype plans. Plans are well-documented as technical drawings with dimensions and tolerances. Excellent mock-up constructed where beneficial. / Clearly based on group’s research. Minor specification errors or omissions are present in prototype plans. Evidence of consideration given to construction, maintenance, and operation. Acceptable mock-up constructed where beneficial. / Loosely based on group’s research. Major specification errors present but few in number. Little consideration given to facilitate construction, operation, or maintenance. Mock-up would be beneficial but has not been constructed. / Unrelated to group’s research. Functional parts that require testing are missing from plans. / Little or no evidence of prototype plans.
Prototype Build Procedure / Procedure is well documented, easy to follow, and results in excellent prototype model. Excellent images used to facilitate/document construction. / Procedure is mostly well documented with minor errors or omissions. Good images used to facilitate/document construction. / Procedure is documented but unclear or confusing in places. Images are not well chosen or not appropriate. / Procedure is poorly documented, mostly unclear and confusing and could result in an unacceptable model. Unacceptable effort to include images. / Little or no evidence of build procedure.
Prototype Design Iteration / The prototype design/construction process involved substantial purposeful iteration; it was supported by clear and thorough explanation of the choices made as the design evolved and of how the final iteration could be improved for testing purposes. The prototype design process facilitates testing by suitable means to the fullest extent realistically possible so that the solution design addresses primary goals. / The prototype design/construction process involved substantial and mostly purposeful iteration; it was supported by clear and well-developed explanation of the choices made as the design evolved and of how the final iteration could be improved for testing purposes. The prototype design process often facilitates testing by suitable means / The prototype design/construction process involved adequate and generally purposeful iteration; it was supported by clear and adequately developed explanation of the choices made as the design evolved and of how the final iteration could be improved for testing purposes. The prototype design process generally facilitates / The prototype design/construction process involved some purposeful iteration; it was supported by somewhat clear and partially developed explanation of the choices made as the design evolved and of how the final iteration could be improved for testing purposes. / The prototype design/construction process lacks iteration. Little or no explanation of the choices made as the design evolved and/or how the final iteration could be improved for testing purposes.
Prototype Construction / Construction free of workmanship defects. No temporary rigging present. Construction shows dimensions and tolerances specified in design drawings. The prototype is constructed with enough detail to assure that some level of objective data demonstrating the success with which the stated goal has been met can be determined through testing, mathematical modeling, or detailed expert reviews. / Adequately constructed but with some obvious defects. Strict adherence to design drawings and notes not observed. The prototype is constructed with enough detail to assure the some level of objective data demonstrating the success with which the state goal has been met can be determined through testing, mathematical modeling, or detailed expert reviews. / Constructed to be functional, but not well executed. Numerous workmanship defects present. Deviates from design drawings to a significant extent. The prototype was constructed with enough detail to assure that some level of object give data demonstrating the success with which the stated goal has been met can be determined through testing, mathematical modeling, or detailed expert reviews. / Dysfunctional, incomplete, or unsafe to operate. The prototype was constructed with minimal detail to convey that the success with which the stated goal has been met can be determine through testing, mathematical modeling, or detailed expert reviews. / No evidence of prototype construction.
Aesthetics / Prototype appears to be professionally constructed. It includes colors, logos, or other visual additions which enhance its appearance. / Prototype is neat, clean, and uncluttered. / No attempt was made to address the appearance of the prototype. / Prototype appears to be in a state of disrepair, has corrosion, blemishes, surface defects, etc. / The prototype is not available for evaluation.
