It is accepted that changes in technology, work practices and the general socio-economic environment affect the way we plan and perform tasks. Support, opportunity and pressure for people to `multitask' has increased. We cannot assume that because an IT is designed well for a single-user single-task perspective, that it will effectively support multitasking. Some work has been undertaken into understanding these phenomena in a HCI context, but with little permeation into mainstream HCI methods. This paper provides an interim report into work into multiple task phenomena within the Task Knowledge Structures task analysis approach. Keywords Multiple task work, modelling, Task Knowledge Structures
