KEY TERMS Flashcards
End user
End user provides feedback to the developer to ensure that the digital system does what it is supposed to
do/meets the end user requirements
Prototype

Target audience
(Demographic) group application is aimed at
User requirements
When a computer system is completed the developer in the first instance will check the completed system
against a set of user requirements to see if they have all been met. After the evaluation any limitations of the
system will be identified which may lead to a further refinements of the system design.
