Design and decision-making

Designing is a process of making decisions for execution. Decisions can be made at any time: long before the decisions are actually implemented, or at the instant of implementation. A product may be designed and then developed into a package which is used in a different time and place, or an intelligent agent can be made to make some or all of the decisions about instruction and implement them on the spot. The great power of both live instruction and (potentially) computer-based instruction comes from the making some or all of the design decisions at the moment of instruction.
