House of Quality

ScopeWith a 5 person team, students should

design and build a working prototype that meets the specifications within the constraints.

Ideal Team- 2 Electrical Engineers 2 Mechanical Engineers 1 Industrial Engineer

FeasibilityFinancial – all of the major

components have been benchmarked for cost. Design is possible with the requested budget.

Time- Project Scoped to allow team to complete within Senior Design 1 & 2 especially if run on semesters.

Skill Constraints- Design feasible for team with requested skill set, electromechanical device requires some background in Controls.
