Model of business processes

1. In paragraph 3.2, you need to add a model of business processes as is before implementation (in bpwin, erwin or in visio), you need a picture and a comment after it (you need a main layer and a layer in which changes will be made)
2. In 3.4, add a business process model to be after implementing SAP ERP (in bpwin, erwin or visio), and then you need a picture and a comment after it! (Same with the main and the one where the changes occurred)

In fact, you need 4 screenshots with their description!
