Event-driven Process Chain Diagrams Examples

There are a few samples that you see on this page which were created in the ConceptDraw DIAGRAM application by using the Event-driven Process Chain Diagrams (EPC) solution. Some of the solution's capabilities as well as the professional results you can achieve are all demonstrated here on this page.

All source documents are vector graphic documents that are always available for modifying, reviewing and/or converting to many different formats, such as MS PowerPoint, PDF file, MS Visio, and many other graphic files from the ConceptDraw Solution Park or ConceptDraw STORE. The Event-driven Process Chain Diagrams (EPC) solution is available to all ConceptDraw DIAGRAM users to install and use while working with ConceptDraw DIAGRAM software for creating diagrams and drawings.

Template 1: Event-driven Process Chain (EPC) Diagram

This template of EPC Diagram is contained in the Event-driven Process Chain (EPC) Diagrams solution located in the ConceptDraw Solution Park. It helps you draw EPC diagrams using ConceptDraw DIAGRAM quickly and easily.

This Event-driven Process Chain (EPC) template explains the meanings of all variety of EPC design elements. The EPC method was developed within the ARIS (Architecture of Integrated Information Systems) framework. For EPC diagrams constructing is applied a common set of event-driven process chain elements that allow making the EPC diagrams of any configurations. Each EPC diagram starts and ends with events represented by hexagon shapes. The function describes the transformations from the initial state to the final state and is indicated by the rounded rectangle. The organization unit represented by an oval shape determines which person or organization within the structure of an enterprise is responsible for a specific function. The system object represents the information system, information flows show the connection between functions and input or output data, upon which the function reads changes or writes. The logical operators represented in the circles are also used extensively in EPC diagrams.

Example 1: EPC diagram — Login and Registration Processing

This diagram was created in ConceptDraw DIAGRAM using the EPC Diagrams library from the Event-driven Process Chain Diagrams solution. An experienced user spent 20 minutes creating this sample.

This computer security EPC Diagram sample clearly illustrates a step by step login and registration processing procedure and depicts how all events can impact the process flow. The login and registration are the basis of computer security they allow you to restrict access to a computer system or other restricted area, allowing the individual access to a computer system only for certain people. During the process of signing in or logging into the system, the user is identified and authenticated based on the data entered by the user. If the user is not logged in, it is checked whether he is registered and for what reason the log in was not performed. And so on, you can see all the registration process steps in the diagram. After completing the work in the system, when the access is no longer needed, the user can easily log out. The use of ConceptDraw DIAGRAM connectors to create EPC diagram is an intuitive and time-saving solution.

Example 2: EPC Diagram — Order Processing

This diagram was created in ConceptDraw DIAGRAM using the EPC Diagrams library from the Event-driven Process Chain Diagrams solution. An experienced user spent 10 minutes creating this sample.

This example shows the Business process modeling (BPM) Event-driven Process Chain Diagram that clearly illustrates an order processing procedure step by step. The order processing is one of the main functions in the process of order fulfillment. The order processing is understood as a complete set of measures, starting from the moment of receiving the order from the buyer and ending with its implementation, including picking, packing, delivering the packed items to a shipping carrier, as well as delivering and transfer the goods to the consumer. The order processing takes some time, but the faster it happens, the more satisfied the customers are, and the higher the success of the producers is. The main steps of the order processing are the following: making an order by the client, order’s analysis, signing the agreement, shipping ordered products, and completing the order. This EPC diagram can be used as visual material for employee training or as a source for any automation initiative.

Example 3: EPC Diagram — Image Processing

This diagram was created in ConceptDraw DIAGRAM using the EPC Diagrams library from the Event-driven Process Chain Diagrams solution. An experienced user spent 15 minutes creating this sample.

This EPC diagram depicts the image processing flow and was created based on illustration published in the article "Methods for the specification and verification of business processes. 19 — Event-driven process chains. Roberto Bruni. 2011". The business process is a sequence of alternating events and functions using the logical relationships AND, OR, XOR represented in the circles according to the event-driven process chain notation. It is convenient to use the EPC IT solutions, EPC method and EPC notation for representing the domain concepts and aspects of the business processes, and for configuring the Enterprise Resource Planning (ERP) implementation. The colors of shapes offered by the EPC Diagrams library from the ConceptDraw's Event-driven Process Chain Diagrams solution significantly differ, thus the event shapes have a brown color, the function shapes are orange, and logical operators are colored by grey. The legend clearly describes all the elements and symbols used in the diagram. It is recommended to create legends to clarify your technical schemes of the EPC.

Example 4: EPC Diagram — Main Process

This diagram was created in ConceptDraw DIAGRAM using the EPC Diagrams library from the Event-driven Process Chain Diagrams solution. An experienced user spent 10 minutes creating this sample.

This EPC diagram sample demonstrates the main process of supplying goods and was designed on the base of the Wikimedia Commons file "EPC priklad1.png". The key points in this diagram are the XOR operations used when the function is completed and executing one of two chains of events. The flow starts with receiving an order for some goods by the company. At the next stage, the order is processed. First, the availability of goods is recognized, they may be available or must be made. You can see the XOR operator and both these options, one of which will be executed. If the goods are available, this means that they are in a warehouse and can be delivered immediately. If the goods are to be manufactured, then the nested production process is started, and when the goods are produced they will also be delivered. You can experiment with the colors of objects, background, and fonts to find the best and most attractive version for your diagram.

Example 5: EPC Diagram — Wikipedia Editing Process

This diagram was created in ConceptDraw DIAGRAM using the EPC Diagrams library from the Event-driven Process Chain Diagrams solution. An experienced user spent 10 minutes creating this sample.

This Event-driven Process Chain Diagram was designed on the base of the “EPC diagram.png” Wikimedia Commons file and illustrates in detail the process of editing articles on Wikipedia helping to understand better this process that may seem rather complicated at a first glance. The XOR and AND operators are used in this diagram. You can see that there are several reasons for editing articles on Wikipedia, these are the errors in articles, or new facts received from the literature or Internet that should to be added to the corresponding article. Typically, anyone can edit any unprotected page with a goal to improve it, at this some pages on Wikipedia are protected from editing. There are used two methods for editing articles on Wikipedia: classic editing through the wiki markup (wikitext) or with new VisualEditor (VE). Use this diagram as a quick guide to make Wikipedia articles perfect.

Example 6: EPC Diagram — Review Process Model

This diagram was created in ConceptDraw DIAGRAM using the EPC Diagrams library from the Event-driven Process Chain Diagrams solution. An experienced user spent 10 minutes creating this sample.

This Event-driven process chain (EPC) diagram sample shows the review process model. It was constructed based on illustration for the "Interoperability in the ProM Framework" article published by H.M.W. Verbeek, B.F. van Dongen, J. Mendling, and W.M.P. van der Aalst on the CEUR Workshop Proceedings (CEUR-WS.org) website. The process begins with the inviting reviewers. Each paper is reviewed by three people; these reviews are stored and then combined. After discussion, you may need to invite another reviewer for an additional review. As a result, the paper may be rejected or accepted. Each activity in this Event-driven process chain (EPC) diagram is represented by a function and depicted as the rounded rectangle, the events are represented by hexagons. The shapes are joined by connectors, among which you can find XOR, OR, and AND. For convenience, the shapes used to create the EPC diagram differ not only by their shape but also by color.

Example 7: Event-driven Process Chain Elements

This diagram was created in ConceptDraw DIAGRAM using the EPC Diagrams library from the Event-driven Process Chain Diagrams solution. An experienced user spent 10 minutes creating this sample.

This diagram sample demonstrates the set of event-driven process chain elements. Being designed on the base of the "Elements of an Event-driven Process Chain.svg" Wikimedia Commons file, it uses the common designations for the basic EPC elements and represents all them in a clear and understandable view. The events are represented by hexagons and are the states that occur before or after a function, and fix some parameters in a certain moment. The functions are represented by rounded rectangles. The events are passive elements while the functions are active. The next element is the organizational unit displayed as an oval, which represents a position in the organization or unit that performs certain functions. Such event driven process chain elements as input, output, supporting system, result event are also presented in this diagram. The logical relationships between the main elements (events and functions) are described by logical connectors in the EPC diagrams, and allow splitting the control flow from one to two or more flows and their synchronizing as well.

Example 8: EPC Diagram — Nested Process

This diagram was created in ConceptDraw DIAGRAM using the EPC Diagrams library from the Event-driven Process Chain Diagrams solution. An experienced user spent 10 minutes creating this sample.

This Event-driven process chain (EPC) diagram sample was designed based on the Wikimedia Commons file "EPC priklad2.png" and represents the nested production process. The nested process is a process that is under a certain action, while it is either large enough or not so important to be included in the main business process. The nested process keeps the diagram strict and clear, makes it easily readable and understandable. If we are talking about a complex and long process, with the help of nested processes it can be easily structured by dividing into the parts and allocating the subprocesses. The presented process starts with the 'Start of production' event, which was called from the main process. Then, this process is divided into three streams: 'Production of boxes', 'Production of manuals', 'Production of action figures' which then need to be combined again, after which the 'Termination of production' event occurs, the subprocess is completed and the main process continues to run.

Example 9: EPC Diagram — Order Processing

This diagram was created in ConceptDraw DIAGRAM using the EPC Diagrams library from the Event-driven Process Chain Diagrams solution. An experienced user spent 10 minutes creating this sample.

This Business process modeling (BPM) event-driven process chain (EPC) diagram sample illustrates the order processing flow. The process starts from the moment when a customer makes an order, then this order is processed and divided into three flows: ‘Feasibility checked’, ‘Registered order’, and ‘Order items processed’. The output data of the process are the product, ordering information, and order item. The logical operator AND is used in this diagram and lets one represent the parallel flows, to depict the separation of simultaneous flows of an activity and to synchronize these flows. It is convenient to describe the business processes of an organization using the EPC notation, which is a generally accepted standard for outlining the organization's activities, and even more convenient and efficient is to have the specialized drawing tools, professional EPC solutions and the ready-made Event-driven process chain vector design shapes offered by ConceptDraw's Event-driven Process Chain Diagrams solution that allows constructing the EPC flowcharts literally in minutes.

Example 10: EPC Diagram — Event and Activity

This diagram was created in ConceptDraw DIAGRAM using the EPC Diagrams library from the Event-driven Process Chain Diagrams solution. An experienced user spent 10 minutes creating this sample.

This EPC diagram sample was constructed based on the "Example of the EPC diagram" illustration published at the "Methodological guidelines and recommendations for efficient and rational governance of patient registries" article on the Parent-Wiki website. This EPC that is the main ARIS model for representing processes depicts the events and activities, and relationships between them. It is a dynamic model that unites the static resources of the business and organizes them to perform the different tasks or activities increasing the business value. You can see the activity in the middle of the diagram, at the top there is an event that activates the action, and below is the event that is activated by the action. When an event activates an action, it creates one or more new events. Since incoming items are input document, input database, and application system, as the output you can see the output database, output document, and the role that carries out activity.
