An Organizational Breakdown Structure (OBS) is a chart or diagram that shows how people in an organisation report to each other. It shows how an organisation is broken up into smaller, easier-to-manage units or departments. It also shows what each unit does and how it works with the other units.
In project management, the OBS is usually used to organise a project team’s resources and responsibilities. The OBS can also be used to show how different departments or business units are set up and how they work together in a larger organisation.
In an OBS chart, the top level of the hierarchy usually shows the whole organisation or project, while the next levels show departments, teams, and individual roles within those teams. The chart can be made in a number of different ways, such as a tree diagram or a matrix. It can also include job titles, responsibilities, and ways to communicate.
By making an OBS, organisations can help make sure that resources are used well, that communication channels are clear, and that everyone in the organisation knows what their roles and responsibilities are.
