	Any visualization which is used extensively by a user over a period of time will be used in the context of that user's daily workflow. It is therefore essential to understand this larger workflow context to design the ~~user interface of a~~ visualization application appropriately. This paper ~~examines~~ in ~~great~~ detail the daily workflow tasks and patterns of work of analysts, managers and software developers in a medium-sized software company. This paper provides strong empirical evidence that users, rather than working on discrete and well-defined tasks, in reality, switch tasks on average every two to three minutes, and instead, work on larger thematically connected units of work (working spheres). In addition, the study found that users switched between these larger working spheres on average every 12 minutes. Thus, it is strongly indicated by this paper that many information workers are in a constant state of rapid fire multi-tasking. This suggests that for a visualization to be relevant to any of these information workers, it would need to fit into, and support, this workflow. This is just a first step towards understanding how users interact with visualizations in particular, however; future work that studies how users interact with visualizations as part of their larger daily work patterns is warranted, and would be an important component of a broad theory of visualization.

HCI - Marking Menus
