What approach is the standard for Business Process Modelling?

The Activity Flow oriented approach is recognized as the standard for Business Process Modelling because it emphasizes the sequence of activities and the flow of tasks within a process. This method allows for a clear visualization of how activities relate to one another, enabling stakeholders to understand how processes operate from start to finish.

This approach captures the dynamic nature of processes, including decision points, parallel activities, and the overall progression of tasks. By focusing on the flow of activities, it becomes easier to identify bottlenecks, redundancies, and areas for improvement, which are essential for optimizing business processes.

In contrast, other approaches, such as Data Flow oriented or Object oriented, typically focus on different aspects of a system. The Data Flow oriented approach emphasizes the movement of data rather than the activities that transform that data, while the Object oriented approach centers around encapsulating data and behavior within objects, which may not provide the clarity needed for visualizing processes in a sequential manner. The Holistic Systems approach takes a broader perspective, examining systems as interconnected entities, but it may overlook the granular detail of specific activity flows.

Thus, focusing on how tasks interlink and flow through a business process makes the Activity Flow oriented approach particularly effective and widely adopted in modelling business processes.
