ABSTRACT
When an architect designs a house or an industrial designer designs a product or artifact, he or she-after consulting with the client and determining the program of requirements-makes a blueprint for the ultimate product. The blueprint for Leonardo da Vinci’s ‘flying machine’ above is an example. Such a blueprint is not just a schematic drawing of the final product, but is rather a detailed plan of action, scheme, program, or method worked out beforehand to achieve an objective. This is also the case for the instructional designer.
