The stakeholders of this project are the buyers, the users, the natatorium, our group,

  • Dr. Colledge, the Consumer Product Safety Commision, and the waste company

From our stakeholder requirements we created a list of design specifications for our product.

Cost Weight Safety Project Requirements

  • Total Cost < $80
  • Seling Price < $100
  • Must be able to hold

a maximum of 200 lbs

  • Must meet the

requirements of the Consumer Product Safety Commission

  • No liquid propellent,

toxic materials, or waste left in pool

  • Must be able to

mount the device from inside body of water

  • Ideally, product

should have speed to race across body

  • f water
  • Must be able to

walk the distance of an Olympic pool Table 2. Design Constraints and Specifications
