  routine workablility
Next, one can check if the routine is workable i.e., wether it is reducible to workable elements, through task-decomposition and means-ends links, or workable dependencies.
In order to provide a stronger notion of ability suitable for strategic reasoning, we introduce the notion of "workability" - to indicate that an agent believes that some routine would work (at "run-time"), even though it is incompletely specified or known (at "strategy-time", i.e. during process analysis or design).(p26)
A routine is judged to be workable if each of its explicitly mentioned elements are workable, and if all of the constraints in the routine are expected to hold. (p26)
Intuitively, an element n is made workable by reducing it through the routine to primitvely workable elements (though not necessarily primitvely executable actions), or by delegating some of the elements to other agents. (p27)
Workability is a local property - it is one agent's judgement about whether its own routine would work.(p27)
When a routine involves dependencies on other agents, the depender agent usually cannot make judgements about the workability of the routines in dependee agents, because it does not know enough about those routines, or the workability of the elements in those routines. (p27)
The notion of "workability" is introduced to provide a second level of analysis, beyond the basic notion of ability. An actor having a routine (and thus ability) means that it knows what to do to the extend that the routine is reduced partially to some elements. But whether the actor believes it is able to successfully carry out or achieve these elements is a separate matter, and is captured in the notion of workability.(p45)
We say that an element is workable if the actor believes (at "process design time") that it can successfully carry it out or achieve it ("at run-time").
An element in a routine is workable if the elements in all of its subroutines are workable. This recursive evaluation terminates either at the actors boundary, where there is a dependency, or at an element which the actor considers to be "primitive workable"(p46).

Commitement
It is important for agents to be able to assess the workability of [their] routines which involve dependencies on other agents [without having the ability of judging the workability of the routines in dependee agents, as they dont know enough about those routines, or the workability of the elements of those [dependees] routines].The notion of commitement offers a way out of this dilemma.
We take the view that if an agent is able to achieve n, and it is commited to doing so, then n is workable for that agent. (p27)
Commitement thus provides an abstraction that allows workability to be judged without having to know about the routines used to achieve n or the need to judge the workability of the individual elements that make up those routines.(p27)
Commitement is the property that bridges the gap between ability and workability. (p27)
If agent y is able to achieve n, and y is commited to achieve n for x, then n is workable for y. We call this the Workability-Commitement Assertion.(p27)
A commited element is workable if there is another actor commited to produce this element as dependum for this first actor.(p46)
[When there is a comitted dependency to some other actor, if the depender actor does lose confidence, or can not judge in confidence that the dependee will deliver the dependum, then the dependum element is considered to be unworkable. This is also expressed by the failure of the Workability Committement Assumtion].

primitive workable element
A primitively workable element is one that is judged to be workable without further reduction. (p27)
This means [to be primitively workable] that the element is judged to be not worth further pursuing/reducing during strategic modelling. The actor is confident that, at execution time, it will be able to carry out the reasoning and actions required to achieve the result.
At an actor boundary, an open element is workable if there is some actor offering this element.(p27)
