What is BPMN?
BPMN (Business Process Model and Notation) is a graphical standard for modeling business processes in Workflow systems. It enables the creation of clear diagrams representing the flow of tasks within an organization. Its primary goal is to facilitate sequential actions by creating clear and understandable diagrams representing the steps of a given process. Used by both technical and business professionals, it allows for easy process communication and automation. Thanks to the uniform and understandable BPMN standards, employees can easily analyze and automate tasks within an organization.
Briefly about a long history
The history of BPMN dates back to the early 2000s, when it was developed by the Business Process Management Initiative (BPMI). In 2005, BPMN was acquired by the Object Management Group (OMG), which further developed the standard, introducing subsequent versions. Today, BPMN is a globally recognized standard, widely used for designing and optimizing business processes across various industries.
Basic BPMN symbols
BPMN uses a set of standard symbols to represent various elements of business processes. These symbols enable the graphical representation of complex business processes in a clear and understandable manner, facilitating their analysis and optimization.
Below we present the basic BPMN symbols and their meanings.
Events
Events mean that something is happening in a process. We distinguish:
- Start events – symbolized by an empty circle indicating the beginning of the process.
- Intermediate event – symbolized by a thin circle with a symbol inside, indicating something that happens during the process (e.g., receiving a message).
- End event – symbolized by a thick circle indicating the end of the process.
Tasks
Tasks represent specific actions performed in a process. They are represented as rectangles with rounded corners. A task can be manual, automatic, user-defined (user task), or, for example, assigned to a specific system (service task).
Flows
Flows are lines connecting individual process elements, indicating the sequence of activities. We distinguish:
- Sequence flow – a straight line with an arrow at the end that shows the order of activities in a process.
- Message flow – a dashed line with an open arrow indicating the flow of information between different entities or systems.
Gateways
Gates are used to control the flow of a process. They represent decision points that direct the process in different directions, depending on conditions:
- XOR gate (exclusive) – splits the process into one of many possible paths (only one is chosen).
- AND gate (parallel) – allows several process paths to be run simultaneously.
- OR Gate (Non-Exclusive) – Can activate one or more paths, depending on conditions.
How does BPMN integrate with Workflow systems?
BPMN integrates with workflow systems through standardized process modeling, enabling seamless translation of graphical diagrams into automated workflows within process management systems. This allows workflow tools to directly use BPMN diagrams to define process steps, assign tasks to employees or systems, and monitor their completion. The workflow system interprets these diagrams as instructions that automate the company’s operations.
Standardized process modeling in BPMN
Standardized process modeling in BPMN allows for the creation of understandable and unambiguous diagrams that are easy to interpret by both IT specialists and operations managers. This approach enables more precise process control, eliminates the risk of errors resulting from ambiguities in information flow, and accelerates change implementation. As a result, BPMN in workflow systems increases operational efficiency, optimizes resources, streamlines communication between departments, and accelerates the execution of key tasks within the organization.
Advantages of using BPMN in a Workflow system
Using BPMN in a workflow system brings many benefits, including easier communication between departments. Thanks to a standardized model, all employees – regardless of their level of technical expertise – can easily understand how a given process works.
BPMN provides clear diagrams that present the steps and tasks within processes, eliminating misunderstandings and improving collaboration between teams. This facilitates information exchange and ensures that all departments operate in accordance with established procedures.
Process transparency
Thanks to the graphical representation in BPMN, processes become more understandable and easier to analyze. Companies can easily identify bottlenecks, unnecessary steps, and areas requiring improvement. This introduces greater transparency into management and enables a better understanding of the entire workflow, facilitating improvements and optimization.
Automation and Efficiency
BPMN diagrams can be easily translated into automated actions, reducing the need for manual intervention in business processes. Instead of repetitive and time-consuming tasks, processes can be completed faster, more accurately, and with less risk of error.
All this leads to improved operational efficiency, cost reductions and greater company flexibility in responding to changing market needs.
Example of using BPMN in process modeling
An example of BPMN’s use in workflow process modeling is the invoice flow process. In a workflow system, BPMN enables graphical representation of all steps in this process, allowing for its automation and optimization.
Example of an invoice approval process using BPMN
- Start Event: The process begins when an invoice is entered into the system. This can be either a manual entry by an accounting employee or the automatic receipt of an electronic invoice.
- Task: invoice verification (User Task): the accounting employee checks whether the invoice data is correct (e.g. amount, contractor details, compliance with the order).
- Decision Gateway: After invoice verification, the gateway decides whether the invoice is correct. If it is not correct, the process moves to the invoice correction task.
- Task: invoice correction (User Task): if the invoice contains errors, it is sent for correction (e.g. to the sales department or to the contractor) and then re-entered into the process.
- Approval Task: If the invoice is valid, it is sent to the appropriate manager or department for approval. This task can be assigned to a single person or a group of people (e.g., a supervisor).
- End Event: Once approved, the invoice is forwarded to the accounting department for payment, completing the process.
BPMN integration with ERP, CRM, and analytics tools
BPMN, as a standard for business process modeling, can be effectively integrated with other technologies such as ERP systems, CRM and analytical tools to improve process management and automation.
BPMN integration with ERP systems
Integrating BPMN with ERP systems allows for precise modeling of processes such as resource management, production, and finance, and then automatically executing them within the ERP system. BPMN diagrams define task sequences, and ERP executes them, ensuring complete control over operational processes and data flow.
BPMN integration with CRM systems
Integrating BPMN with CRM systems enables the automation of customer service, sales, and marketing processes. BPMN allows you to define customer interaction paths, from contact initiation to sale completion. This, combined with CRM, ensures that every step is monitored and managed consistently. This allows companies to better personalize customer communications and manage relationships more effectively.
BPMN integration with analytical tools
BPMN can also work with analytical tools, where business processes are not only automated but also analyzed in real time. Integration with Business Intelligence (BI) tools enables monitoring of key performance indicators (KPIs) and identifying areas for optimization. Data collected within defined BPMN processes can be analyzed to improve operational efficiency and make better strategic decisions..
