Task (work task)
A task is a specific piece of work required to be done Task analysis is the breakdown of a particular job into its component parts and examine, for example, the information needed.
Information science has increasing focused on the role of information associated with kinds of tasks. One way in which different tasks may put different demands on information systems is described in the following quote:
"Why multiple taxonomies? As a first cut, we tried to find a taxonomy that reflects the notions of generalization and specialization within mathematics. In experiments done before the meeting, and in discussions during the meeting, it became clear that disparities in vocabulary usage among different levels of mathematics made a universal taxonomy impractical. The assumptions made by someone searching in the realm of research mathematics and someone searching in the context of a precalculus course are remarkably different, and the same vocabulary means far different things. Not only do words change their meaning as the level of mathematics changes (think of the word "sequence" and what it means to a middle school teacher, in Calculus, in Number Theory, or in homological algebra) but so can the relationships among subjects within mathematics." http://www.mathmetadata.org/ammtf/docs/june99/maintax.htm
