Engineers are testing a solution to a problem. The solution is failing. What should they do? CHECK ALL THAT APPLY

• consider using other materials for the design

• understand that sometimes things do not go as planned

• decide not to develop other solutions for the problem

• Use random variables

Why is it important to identify failure points in a prototype?

• To make the prototype more expensive

• To understand which parts need improvement

• To ensure the prototype is perfect
