A task is the application of a skill on a defined product type with a desired outcome. They form the relation between product and skill, defining the executing resource implicitly.

The fully platform-independent specification of the manufacturing scenario. It contains references to assembly and contact graphs on one side, and to the workpiece descriptions on the other. However, there is no specific, platform-related information available in the task description yet. Tasks form a hierarchical structure, with sub-tasks decomposable into lower-level task structures.

A task is a process from a requirements point of view without a specified solution. A task has an initial state I (initial) and a target state G (goal). The transition between these is unknown. The solution space of the task can be restricted by conditions at the transition.
