Your First Design ExerciseYour First Design Exercise

Suppose we are to give out an award for excellence in software design. Create a design for this award…

…and be able to explain its meaning…

…in 10 minutes…

…and money is no object.

(We will take some pictures)

Your Second Design ExerciseYour Second Design Exercise

Create a design for your ideal classroom “seat” to be produced and sold by a major retailer…

…using any of the following…– paper– pencil– wire– wire cutter– Play-Doh

…in 20 minutes.

Cost is a concern, and this will be also be your final design that you hand off to the manufacturer for production.
