Mission Statement: To design and build a device that can effectively walk across a body of water and is able to be sold to consumers.
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
After surveying our potential buyers, we were able to identify and rank our 4 design specifications Safety Durability Ease of Portability Operation Row Total Row Totals Total 1 2 5 7 15.00 0.474 Safety Durability 1/2 1 4 5 10.50 0.332 1/5 1/4 1 3 4.45 0.141 Easily Operable 1/7 1/5 1/3 1 1.676 0.053 Portability Total: 31.626 Table 1.

From our stakeholder requirements we created a list of design specifications for our product. Cost Weight Safety Project Requirements ● Total Cost < $80 ● Must be able to hold ● Must meet the ● Must be able to ● Seling Price < $100 a maximum of 200 requirements of the mount the device lbs Consumer Product from inside body of Safety Commission water ● No liquid propellent, ● Ideally, product toxic materials, or should have speed waste left in pool to race across body of water ● Must be able to walk the distance of an Olympic pool Table 2.

We established a certain number of subsystems to make the design process more efficient Survey Market research Stakeholder requirements Group 6 Digital CAD Design Analysis Buy materials Fabrication Manufacturing
We did the calculations for our original design to ensure that it would float and hold our maximum weight
After our first design was unsuccessful, we redesigned and redid our calculations for our new prototype
