Molly would like to design a dog collar that has a short leash capable of winding back into the collar. She has researched the market and found that there are no similar products currently for sale. She has also conducted focus groups with pet owners and received feedback
about what potential customers would like to see in a new product. She has found her best option: a thin but durable material that can
feed back into the collar.
After reading the above scenario, which design phase would you conclude comes next?

A. Identify the need
B. Preventative maintenance
C. Build a model
D. Explore possible solutions
