Relation Manages

Notes for Manages:

A single sequence of Actors directly connected via the Manages Relation can be thought of as a management chain. More precisely, all management chains have: * Only one Actor (lowest level) that does not Manage another Actor; * Only one Actor (highest level) that is not Managed-By another Actor; * No branching (i.e. no Actor is Managing or is Managed-By more than one other Actor).
An Organisational-Unit at the lower end of a Manages chain may correspond directly with one Person. The Purpose s of such a Person may be very similar to the Purpose s of the Organisational-Unit and therefore the Purpose s may not need to be separately modelled. Higher up a Manages chain, the Purpose s of an Organisational-Unit are likely to be dissimilar to the Purpose s of a Person.
Informally, a Managed Organisational-Unit can be thought of as being `part of' the Managing Organisational-Unit.
Insofar as a Machine is Managing or is Managed-By another Actor, it may be considered to be an Organisational-Unit.
One ordered pair in this relation corresponds to a case of one OU managing another and is referred to a Management-Link
The manner in which the Management Links are arranged is referred to as the Organisational Structure. * Examples of common Organisational Structures are hierarchical (e.g. line management), matrix (for project/programme management) and flat. * Co-management is a situation where an Organisational-Unit is Managed-By more than one Organisational-Unit.
