What are the three levels of the business process hierarchy?

Business processes are typically organised into a three-level hierarchy to manage complexity and

provide a clear line of sight from strategy to execution. The standard levels, moving from the highest

to the lowest level of detail, are:

Enterprise (or Value Chain): The highest level, showing the core business functions (e.g., "Sell

Product," "Develop Product").

Event-Response (or End-to-End): The mid-level, showing the process triggered by a business event

and concluding with an outcome (e.g., "Handle Customer Order").

Actor-Task (or Detailed/Procedure): The lowest level, showing the individual steps and actions taken

by the actors to complete a process (e.g., "Check stock availability," "Package item").

Therefore, the three key levels that define this breakdown are Enterprise, event-response, actor-

task.
