Design what is it?

Design what is it?

Design as an activity in its own right ● different to science, art, music ● science explains ● art, music express emotions

Design an activity in its own right ● the production of an entity (or its representation) to satisfy a given set of requirements

Design as an activity in its own right design creates

Design as an activity in its own right design has changed the world

Design as an activity in its own right a purposeful act

Design characteristics ● function / purpose ● behaviour ● structure F B S F B S P

Design characteristics ● function / purpose ● behaviour ● structure why / what does how does what is

Design characteristics ● function / purpose ● to tell the time ● to adorn the wearer ● to advertise status ● behaviour ● by pointing to appropriate marks ● being visible ● be attractive, stylish ● structure ● gold case /strap, glass face, gold hands, …

Design characteristics ● function / purpose ● to promote Faculty ● to inform ● behaviour ● by projecting an academic image ● by projecting an attractive look ● by displaying accurate & complete information ● by being easy to use / navigate ● structure ● text, graphics & multimedia ● type, shape, size, colour, location, orientation, tone, loudness, …

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

actual behaviour analysis Design processes function required behaviour evaluation reformulation problem formulation synthesis structure redesign description documentation

Design classification ● routine design ● finding values for structural variables ● innovative design ● extending the values of structural variables ● creative design ● creating new variables, new types

Design Prototypes an object-oriented representation for design

Designing with Design 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 20
