Set up and work through the 5 stages of a project. Mix and match worksheets to create your own projects.
(See readymade projects for examples.)
Start a project by filling in a cover sheet and understanding the design process.
Decide on who you want to design for, and what you want to help them do.
Know the people you are designing for, so you understand their needs better.
Dream up lots of different solutions that might be useful to people.
Turn your ideas into something more real, so you can test them out on people.
Show your prototype to the people you designed for, to see what they think.
