Gather Information
Use a KWL chart What information must we locate?
Perform the research

Brainstorm Alternative Ideas
All ideas are ok This begins the creative part
Any format is ok. (words, sketches)

Decide on the Final Design
Narrow down the possibilities Decide on the best idea
Justify the idea

Test and Evaluate
Does it work as anticipated? Does it meet all criteria and constraints?

Redesign or Refine
If it works, improve it. If it doesn’t work, redesign it.
What went wrong? How can we fix the problem?
