An organization chart is any graphic manifestation of project reporting relationships. It gives you the big picture of how your project fits into the overall activity of the organization. It shows the relationships:
- between resources of the project management system
- of formal authority between groups and individuals.
Organization charts vary dramatically from one organization to another. They do, however, have some basic elements in common. For example:
- All members of the project are identified, including stakeholders.
- Data can be formal, informal, detailed, or general.
- Direct relationships between people are shown with a solid line.
- A dotted line indicates an indirect relationship, or a relationship that has not been clearly defined.
There are also drawbacks to using a traditional organization chart. For example, a traditional organization chart:
- doesn't show the nature and limits of the activities required to attain project objectives
- doesn't show the reciprocal relationships between people, which often occur within a project
- may not accurately reflect the structure throughout the project because it is often out of date very quickly
- may confuse people, as the pyramidal structure may portray a false sense of status and prestige.
An OBS identifies the roles and responsibilities of the individual as well as those of the collective project unit. And OBS is a concise description of the organizational interfaces. It illustrates:
- who the project participants are, the extent of their involvement, and their authority
- when decisions should be made or activities performed
- who has authority when team members share common work
- work packages or tasks necessary for project success.
A standard organization chart or Organizational Breakdown Structure Chart provides you with concise information concerning responsibility relationships within an organization. Both types of charts provide a useful tool of reference for everyone involved in the project.
