'Task has several meanings:
- In common language, a task is part of a set of actions which accomplish a job; the sense is that 'useful work is getting done'. Task analysis is the analysis or a breakdown of exactly how a task is accomplished, such as what sub-tasks are required. This information can then be used for many purposes, such as improving the design of tools or procedures that aid in performing the task. These tools can be either physical implements or software.
