Q.3.
Engineers test 4 dishwashers, models A through D. The engineers discover that dishwasher model B does not clean the dishes well. Which is the next step for the engineers?
Make and sell the model B dishwasher anyway.
Start all over with a brand new design for a dishwasher.
Evaluate what is wrong with model B and work to redesign it.
Choose a different appliance to make and sell instead of dishwashers.
Q.4.

add new criteria
use the same criteria
change all the criteria
get rid of old criteria
