Explain the engineering design process.

Explanation may include the following iterative steps:

Identify the need or opportunity for an engineering solution by listing the criteria and constraints.
Establish a system for documentation of workflow.
Research potential solutions to the design problem.
Generate (brainstorm) multiple solutions to the design problem.
Justify an optimal solution to the design problem.
Create a model or prototype for the chosen solution to the design problem, using appropriate materials and processes.
Test the solution to the design problem, using mathematical, conceptual, and/or physical modeling, simulating, and optimizing.
Redesign the solution.
Test the alternate solution.
Communicate the solution and results.
