The Industrial process and Office process model types essentially represent the same facts as the EPC model type or EPC (material flow), with the difference that they provide only a limited selection of objects and the symbols are represented in graphical form

This kind of graphical representation has the advantage that employees in the operating departments can understand the models without training and are able to adjust and develop them themselves. For instance, it is easy for every user to see that a symbol showing three persons represents a group, whereas this is not as obvious in the abstract EPC symbolism (oval with double frame). Therefore, the goal of these two model types is to establish process modeling, process optimization, and process utilization in the operating departments.--

To maximize the identification with symbols, two process types (model types) are provided: the 'Industrial process' illustrates production processes (which create material goods/products), while the 'Office process' illustrates office processes (which create intangible goods/services).

The models can be displayed in all three model types (if the objects exist in the corresponding model type) by copying the content of one model type to another. When copying, ARIS automatically converts the symbols. The following figure illustrates an example of the same fact being displayed in three model types - EPC, Industrial process, and Office process.
