Mission Statement - It was our mission to grab the opportunity to make money by building a device that would
allow the user to “walk” on water.
Stakeholders, functionality- Any customer that wishes to walk on water and ANGEL investors are our
Needs assessment - Define the Scope: To make money off our design, Gather Raw Data, Interviews, Focus
Groups, Observation, Interpret Raw Data, Needs statement, Organize Needs, Hierarchy, Establish Importance, Surveys, Quantify needs, Reflect on the Process, Continuous Improvement
Design specifications-
1. Walking- bipedal motion; legs move independently 2. The device must be portable 3. Meant for people ranged from a certain age group 4. The device should be able to handle different people of different sizes and weights 5. Should be stable 6. Should be able to be used over many years 7. Easy to dispose of should it break 8. The person using the device should be moving in a motion similar to walking

➢ System - Twin Ski like system
○ User shuffles rather than steps ○ Allows flap subsystem to work
Fig 9. Skis together Fig 10. Front, Back
➢ The Subsystem - Flap design
○ Underneath skis to displace water ○ Allows user to glide forward on water
