Unintended Functions
● not purpose of design
● side effects● e.g. cars – exhaust, space, momentum
● may find new purposes● ‘good’ and ‘bad’● cup for measuring, car for ram-raiding

Designing withDesign Prototypes● routine design
● given a specific design prototype instantiate values of variables
● innovative design● select appropriate design prototype extend range of variables by adding new values new subclass
● creative design● create new high-level design prototype new variables &/or new combinations
