The Organization Hierarchy is the backbone of the software in that it acts as a content filing system. Think of it as a folder structure with each folder containing content - a Scorecard, Dashboards, Reports etc. - pertaining to a specific business unit in your organization.
Upon logging into the software, navigating to any of the left-side functionality links will present you with the "Organization Hierarchy" tree. Select an Organization from that list and that selection will be remembered for the remainder of your login session.
Your selected Organization will continue to be displayed at upper left as you navigate from the Scorecard section to the Dashboards section to the Briefing Books section, etc. Any content that you view - or create - is housed within the selected organization.
Want to switch to another Organization? That's easy! Click on the displayed "Organization" selection at upper left and the software will quickly present the entire "Organization Hierarchy". Simply select a different organization within the tree. The "Organization Hierarchy" pane will quickly vanish and you will now be looking at content relevant to the newly selected organization.
Another important point re. Organizations - they are the fundamental building blocks behind security permissions within the software. You can restrict users to only view content - and/or "do things" - to one or more specific Organizations within the larger hierarchy. Users can belong to many security groups, hence it is possible for a user's permissions to vary from one organization to the next.
