If these are the specifications, what

criteria will you be looking for in the

team’s design?

What does the team need to show you

to conince you the design will do

what is needed?

!id the team meet these re"uirements

in its design solution? #ow do you

know?

"his team puts its conclusions at the end and didnot use informative headings on its process flowdiagrams. "he headings do not outline the

argument.

# pitch that presented the recommendation firstand gave evidence of calculations to support

claims would have been more persuasive."he PP" can’t reinforce the oral message orpersuade readers on its own.
