Choose Your User

​

​

​

​

​

​

Engineers design solutions with a user in mind.

​

Users:

  • Can be a person, a group, or a part of the environment
  • Help define problem, the criteria and the constraints
  • Provide feedback on the solution and help determine success

Choose Your Engineering Focus

  • Each member of the team will have a different engineering focus.
  • Decide who will be a(n):
    • Coastal Engineer
    • Environmental Engineer
    • Structural Engineer
  • Decide on the name for your engineering firm.

DEFINE:

  • What is the problem? What forces/factors are involved?
  • What is causing the problem?
  • Who does the problem affect?
    • Who is your user?
    • What do they need?
  • What solutions have been tried?
    • How have others approached it?
    • What were the successes of prior solutions?
    • What were the challenges of prior solutions?

IDENTIFY:

  • What is the criteria for success?
  • What are your constraints on your solution (e.g: time, money, materials, etc.)?
  • Any other things you should consider?

BRAINSTORM:

  • Brainstorm ideas.
    • What are some solutions to the problem?
    • What forces need to be overcome?
    • What materials are best to use?
      • Cost, availability, environmental impact, aesthetics, comfort, etc.

SELECT:

  • Select the most promising solution
    • Consider the users (what do the little pigs want and need)
    • Consider criteria and constraints
    • Yes, and… (combine ideas and points of view)
    • Draw a labeled diagram

  • PROTOTYPE: Follow your plan to create your solution.
  • TEST: Test and evaluate your prototype
  • ITERATE: Improve your prototype.
    • What works? What doesn't?
    • What could work better?
    • Modify your design to make it better.
    • Test it out!
