Design should include
- defining the problem
- performing background research
- generating ideas
- selecting a solution
- justifying the solution
- sketching a prototype
- making a prototype of the device
- documenting the process
- evaluating the device
- reiterating the process.
Process/Skill Questions:
- Why is user involvement crucial for design?
- At which points in the design process should users be involved?
- Why is it important to test functionality and user interface long before the prototype is fully implemented?
