(Optional) Justify calculations and assumptions made during the design process.

Justification should include

• examples of research of similar design problems and solutions to obtain supporting data
• software simulation of material/structural testing
• use of the design process model
• mathematical calculations of specific materials used.

Process/Skill Questions:

• Why is it important to provide information to justify production decisions?
• What are the steps in the design process model?
• What external forces or conditions might affect a design?
• What has made similar designs succeed or fail, and how does this design compare?
