Editing Activity theory (section)

===The internal plane of action===
Activity theory provides a number of useful concepts that can be used to address the lack of expression for 'soft' factors which are inadequately represented by most process modelling frameworks. One such concept is the internal plane of action. Activity theory recognises that each activity takes place in two planes: the external plane and the internal plane. The external plane represents the objective components of the action while the internal plane represents the subjective components of the action. Kaptelinin defines the ''internal plane of actions'' as "[...] a concept developed in activity theory that refers to the human ability to perform manipulations with an internal representation of external objects before starting actions with these objects in reality."<ref>Kaptelinin 1996, p. 51</ref>

The concepts of motives, goals and conditions discussed above also contribute to the modelling of soft factors. One principle of activity theory is that many activities have multiple motivation ('polymotivation'). For instance, a programmer in writing a program may address goals aligned towards multiple motives such as increasing his or her annual bonus, obtaining relevant career experience and contributing to organisational objectives.

Activity theory further argues that subjects are grouped into communities, with rules mediating between subject and community and a division of labour mediating between object and community. A subject may be part of several communities and a community, itself, may be part of other communities.
