doing research
choosing one solution
identifying the problem
communicating results
It's probably on page 56 in your book. Good luck finding it!

An engineer is developing a new design for a tram. The engineer has three designs to choose from. Which design should the engineer select?
The quickest one to produce.
The most costly one to make.
The smallest one.
The one that meets the most important needs.
