The Strategic Rationale Model
notion of task decomposition

task decomposition links

There are four types of task decomposition links - subgoal, subtask, resourceFor, softgoalFor - corresponding to the four types of nodes. These links also can connect up with dependency links in Strategic Dependency model(s), when the reasoning goes beyond an actor's boundary.(p31)

subgoal decomposition link

subtask decomposition link

resourceFor decomposition link

softgoalFor decomposition link

at actor boundary outgoing link

[At an actor boundary,] An outgoing dependency link [the actor being a depender] is usually also a task-decomposition link, the dependum being one of the task components. (p35)
