The organisation structure of a traditional business and the structure of the business processes
often differ. The business processes that produce the value to the customer often run across
departments rather than following the flow of the most important processes. In more modern
organisations, the structure of the organisation has been optimised to follow the flow of the process.
Modelling the structure of the organisation in terms of the business workers, their responsibilities,
relationships and the departments they belong to, can help understand the most appropriate structure
for the organisation as part of business process re-engineering and improvement. It also provides
candidate system actors and use cases for the system requirements model and helps the business
analyst to think about potential areas for automation.
