Homemade Business Process Description Notation

When developing a single project, including the automation of a business process, I wanted to illustrate our offers to the Customer of the functionality as clearly as possible, in a compact and understandable way. Perhaps I was also driven by the desire to draw in the document one main drawing on which to place everything at once.

At first, I drew a simple vertical flowchart of the process. Then, on the right, I drew the participants to it (both people and the system itself). Then he drew the system objects accompanying the processes (in this case - registration sheets) and their states at different stages. And finally, he added the information consumed at each stage. The result was this:



The scheme notation is structurally close to EPC, but compared to it, it is more presentable and intuitively understandable not only to IT specialists. I also consider the advantages of this scheme:
')

• reflection of the sequence of actions in the form of a simple flow chart familiar to most people;
• the presence in the scheme of pictures of participants in the process - both users and the information system;
• reflection on the diagram of which information objects will be created as a result of certain actions;
• reflection of the sequence of stages of the process and their compliance with the states of objects in the information system;
• reflection on the scheme of both consumed and generated information;
• information density and compactness of the scheme, allowing to place it in the book format of a standard A4 sheet.

Thanks for attention!
