Production should include
•    use of appropriate tools and materials
•    a scaled model or working prototype.

Process/Skill Questions:

•    How does one develop the model to resemble the drawing?
•    What proportion/ratio is appropriate for the model?
•    What materials and tools are required?
•    When creating the model or prototype, what issues arose that had not been considered during the planning stages?
•    How did those issues force changes to the plan?
•    What was the reasoning for making those changes?
•    Why should a model use the same materials as the prototype?
