| # Enterprise model A model representing a company's business in relation to the Enterprise Resource Planning (ERP) software that is used for the control of the business. The principal purpose of the enterprise model is the implementation and configuration of the ERP software, but it can also be used for business process reengineering. After the implementation of the ERP software, the enterprise model serves as a basis for the user interface (user-specific menu) and authorizations. An enterprise model is a multilevel structure that consists of the following components: Enterprise-structure Model Business model Business-control model Business-function model Business-process model At the top level of the enterprise model you will find the enterprise structure diagrams that consist of several enterprise units. One level below the enterprise structure model you find business models. Business models can be linked to enterprise units. This relationship implies that the enterprise unit is the indirect link between an enterprise structure model on the one hand and multiple business models on the other hand. Example
     																	Enterprise structure model

    																															|
    																															v
    				Enterprise unit A 		Enterprise unit B 	Enterprise unit C
    											| 																		| 																	|
    											v 																		v 																	v
    			 Project model 1 				Project model 2 				Project model 2
In the example, two different project models (1 and 2) are linked to one enterprise structure model through three different enterprise units. Because a project model is used to set parameters at ERP company level, only one business model must be used to represent one ERP company. Therefore, enterprise unit A and B (see the example above) must be part of two different logistic companies. Obviously, you can still use one project model to configure several companies.
