Abstract
Much information and knowledge work (with and without information
technology) can be characterised as multitasking and interrupt driven.
A whole host of characterisations and buzzwords imply an increase
in the number of roles, tasks/activities, IT artefacts, interruptions
and exceptions that people have to deal with. This provides a challenge
for Task Analysis approaches as they have historically focussed around
single tasks and users. A preliminary version of a composite modelling
approach (the Composite Multitasking Model) is presented that draws
from approaches that model task, events, interruptions, exceptions
and the temporal aspects of tasks. As well consideration of how information
about multiple tasks is elicited, we apply the approach to the modelling
of data from our own studies.
