When basic agencies are grouped together conflicts or synergies of interest can be created. We have done some work on an outline of the theory of composition of roles based on conversation analysis. Job design involves the grouping a specific set of agencies and assigning them to an individual person. A person brings a set of capabilities and resources and a set of external commitments to this composition and human and social factors are critical in evaluating the resulting policy and design decisions. The critical question in this process is whether it is rational, appropriate and acceptable to llocate and accept the implied set of obligations given the access and rights over resources which are associated with the composite role.
Similar considerations apply to the allocation of roles to organisational units.
Such units are termed units of enterprise and the resulting role is termed a mission 5. One or more units of enterprise can be defined as an actor by assigning its resources and relationships to create a market actor , an institutional actor or an association depending on the nature of the mission and the sphere of action. In each case, the set of units of enterprise must be composed with an appropriate organisational structure to provide the required direction, management and execution of the enterprise mission. Summary We have now named and illustrated our basic concepts, identified the set of relationships that can exist between them and constructed a set of composite concepts. We have ensured that, just like the object models which have been developed to structure computation, our enterprise concepts are also highly compositional - it would be surprising if this were not the case.
