Define business process modeling abstraction

There are typically three levels of abstraction:

1. High-level abstraction (or conceptual): This provides a broad overview of the process, focusing on the main stages and their sequence without going into detailed steps. It's useful for understanding the overall purpose and scope.

2. Mid-level abstraction (or logical): This level provides more detail than the high-level view, breaking down the main stages into key activities and decisions. It's useful for understanding how the process generally operates.

3. Low-level abstraction (or physical): This is the most detailed view, showing every single step, task, decision point, and event within the process. It's essential for implementation, automation, and detailed analysis.

Choosing the right level of abstraction depends on the purpose of the model and the audience who will be using it.
