ESIS Framework implements the notion of Groups which can used to group ESIS users and, for instance, facilitate the management of Expertise, etc.
A group can be either specifically assigned to a company or be global. If a group is assigned to a specific company it's visibility and usage scope is strictly restricted to this company, and this group can be transformed into a department.
If the group is global then its scope encompass all the companies managed in ESIS including the slaves one.
For example, let's assume an ESIS implementation where a company has been created for each subsidiary and another for the Holding (mother). Each company has been affected in a separate data-warehouse to ensure clear segregation of datas. Then each subsidiary could have a distinct IT-SEC group to gather all the IT Security team members and a global group IT-SEC could encompass all these groups.
Another example, let's assume an IT Outsourcing company which has an ESIS data-warehouse per outsourced customer, then a global group IT-SEC could be used to transversally encompass all IT staff that works on Security and a dedicated vertical group per customer for only the customers staff and the outsourced staff assigned to it.
ESIS Framework keeps a full historical track of the changes on Groups.
A department is a specific kind of a group. A group that is assigned to a company can be flagged as a "Department" in which case it is considered to correspond to an organizational unit of the company. Department are, for instance, used when mapping with Active Directories or when defining an Audit perimeter.
A department can be assigned domains name (i.e. subsidiary.example.com, subsidiary_product.com) which can then be used to links specific metrics/indicators to this department.
A department can be linked to locations.
ESIS Framework embedds a geographic referential that enables to define the organisation geographical structure.
A Location is the smallest geographical unit, it can a site, a building, a room, a rack in a datacenter, etc., whatever is the lowest geographical unit that is to be managed. A location can be linked to an ISO (continent, sub-continent, country, region) as ESIS embeds the ISO referential, and to a timezone.
Location can have aliases, be assigned internet domains, and network ranges. These are used to map specific metrics/indicators to this location.
ESIS keeps a full historical track of the changes on Location.
Business zones enable to map the corporate map of the world. For instance, an EMEA business zone could be created to regroup all the European locations plus Israel and APAC for most of Asia and Pacific locations except China, etc. And Business Zone of Business Zone could be created to assemble all the locations into the usual MBA Map of the World !
