Abstract
Analysis of information utilisation (AIU) is a method for specifying how
information entities encountered in information analysis are being
physically manipulated in the work situation undergoing analysis. It
focuses especially on factors affecting cognitive load. The method supports
the human-computer interface designer with relevant and appropriate
information structured specifically for a document oriented design
methodology. It gives a suitable basis for user centred interface design,
without the possible limitations that improper user participation could
cause, and focuses on all aspects relevant for a "good" work environment,
such as competence, organisation, work activity and information technology
development.
Analysis of information utilisation is performed through
"observation-interviews" in which a human-computer expert interviews a
typical user about his work situation in the domain of work and observes
information handling routines that the user might not be aware of. A number
of development projects have shown that this method can constitute an
additional step in existing methodologies for capturing aspects of the
work situation that can be directly design controlling. This paper
describes the method of analysis of information utilisation, and what
information that has to be documented while performing the method. It
suggests how the method can be incorporated into existing in-house
development methodologies, and gives an example of documented analysis
results from a development project within the Swedish National Tax Board.
