The brackets are meant to be installed on tablets that are 30 inches high. The 90° mounting angle does not provide optimal viewing. The design group tries to find the optimal angle for the mounting surface.
Which step of the design process is the group working within as they make this decision?
Define Problem
Develop Solution
Evaluate Solution
Test Prototype
While the design group tests the first prototype, they notice that the screws used to mount the brackets scratch the surface treatment. The group decides that more research on existing technologies should be conducted.
Which steps of the design process are the design group working within as they notice the screws used to mount the brackets scratch the surface treatment? Select the three that apply.
Define Problem, Develop Solution, Evaluate Solution

The design group finds some various thicknesses of steel and aluminum and creates brackets to observe how each material performs.
Which step of the design process is the design group working within as they work with different materials?
Construct and Test Prototype
Define Problem
Develop Solution
Evaluate Solution
The design group proposes a few solid ideas and compares them to the design constraints. Each idea is ranked according to how it fits the criteria. The rankings are used to choose which idea to develop.
Which step of the design process is the design group working within as they develop rankings for ideas?
Generate Concepts
Test and Evaluate
