Oops, I thought I designed it right…
When designing architecture, one needs to draw its structure first. The same is true for business processes and frontline operations.
The PReP model is an ideal method for analyzing and designing the process structure. The model’s effectiveness has been proven in many projects, including business process improvement, service development, and system requirements definition.

Designing structures for business processes and operations
There are two approaches to modeling business processes and operations: task-based process modeling and entity-based process modeling.
Task-based process modeling describes an action in terms of a relationship in chronological order. While this modeling method intuitively describes a business process and is therefore easy to use, it has some drawbacks, such as the mixed granularity of what is described and the difficulty in determining whether the description is comprehensive or not.
Entity-based process modeling is a method that can analyze and design a process as a structure. However, the conventional method is complex to use, and the resulting output is complicated to model.
The PReP model is a simple method that is easy to understand and apply. It succeeds in overcoming the disadvantages of entity-based process modeling while maintaining its advantages. Its effectiveness has been proven in many projects, including business process improvement, new service development, and IT system requirements definition.
