Poor design criteria are responsible for wasting computer users time and are a hindrance to effective interaction with human centred systems. It is important that before any design of an interface is attempted an in-depth analysis of task and user needs must be undertaken. Questions need to be asked such as “What takes place during interaction between the user and the interface?” “Does the interaction produce the desired result?” ”Can the interface be easily changed to accommodate evaluation feedback?”
