What is BPMN method and style?
The Method and Style approach allows BPMN models to be shared across the business, or between business and IT, revealing the process logic consistently and unambiguously from the diagram alone. The second half of the book, the BPMN Implementer's Guide, is addressed to developers and BPMN tool vendors.
Why to use BPMN over flowcharts?
Flow charts have not evolved in terms of the notation, while BPMN is a notation defined by a group composed of companies highly engaged with the evolution of business process modelling. Using a standard like BPMN, you have a set of rules that are the foundation for modelling business process models understandable by a wider audience, rather ...

What is a BPMN diagram?
What is a BPMN Diagram? BPMN is an open standard notation that utilizes visual modeling language or diagrams to define business process workflows. This visual modeling language help specify enterprise process workflows through its intuitive business analysis applications.
What is a message flow?
A message flow is a sequence of processing steps that run in the integration node when an input message is received. You define a message flow in the IBM® Integration Toolkit by including a number of message flow nodes, each of which represents a set of actions that define a processing step.
What is sequence and message flow in BPMN notation?
There are two types of flow in BPMN, they are sequence flow and message flow. Sequence flow is used to show flow of works within the organization. Message flow is used to show messages passing between organizations. Normally, workflow is referring to the flow of tasks with sequence flow.
What are three types of BPMN flow elements?
Connecting objects are lines that connect BPMN flow objects. There are three different types: sequence flows, message flows, and associations. Sequence flow symbol - Connects flow objects in proper sequential order. Message flow symbol - Represents messages from one process participant to another.
What is BPMN process flow?
What is BPMN? Business Process Modeling Notation (BPMN) is a flow chart method that models the steps of a planned business process from end to end. A key to Business Process Management, it visually depicts a detailed sequence of business activities and information flows needed to complete a process.
How do you use message flow?
You can define a message that passes by message flow and visualize it. To do this: Right click on the message flow that you want to model its message and select Open Specification... from the pop-up menu. Click on the drop down menu of Message and select Create Message (Business Process) from the pop-up menu.
What are the three types of activities within a process in BPMN?
There are basically three BPMN activity types:BPMN Task.BPMN Sub-Process.BPMN Call Activity.
What are swimlanes in BPMN?
Swimlane objects (aka: Swimlanes) in BPMN are rectangular boxes that represent participants of a business process. A swimlane may contains flow objects that are performed by that lane (participant), except for black box that must have an empty body (we will talk about black box later on in this tutorial).
What is the difference between a swimlane and a pool?
At a glance, both swimlane elements look very similar. However, they have completely different meanings. A Pool represents a participant in a business collaboration and may act as a container for a single process, whereas a Lane represents an “activity-classifying mechanism”.
What are flow objects?
1 Definition A graphical object that can be connected to or from a Sequence Flow. In a Process, Flow Objects are Events, Activities, and Gateways. In a Choreography, Flow Objects are Events, Choreography Activities, and Gateways.
What is the difference between BPMN and flowchart?
Business process modeling and notation is a flowchart method of graphing a business process. It's done exactly the same way as you'd create a flowchart process map, the only difference is that BPMN comes with its own symbols and elements.
What is the difference between BPM and BPMN?
What's the difference between BPM and BPMN? While the BPM is a subject, or a managing philosophy that can be applied to businesses, the BPMN is an official standard notation created by this subject, which is used around the world.
What are the key elements of BPMN?
There are four main elements of a BPMN diagram: flow objects, connecting objects, swimlanes, and data.
Correcting invalid flow
As mentioned before, you can use sequence flow to connect flow objects within a participant and use message flow to connect flow objects in separate participants.
Modeling and visualizing message pass by message flow
You can define a message that passes by message flow and visualize it. To do this:
What is sequence flow?
Sequence Flows. Sequence flow is used to connect flow elements. It is shown in solid line with an arrowhead. It shows the order of flow elements. You can only use sequence flow to connect flow elements within the same pool: either within the same pool/lane, or across lanes in the same pool.
What is a flow element?
Flow elements refer to elements that are connected together to form a complete process flow. Connectors that connect the flow elements are called connecting objects. Readers of BPD follow the flow of elements to see how a business process gets executed and completed.
What are the two types of flow elements?
While there are four kinds of flow elements: Activities (Task and Sub-Process), Events and Gateways, there are mainly two kinds of connecting objects: Sequence Flows and Message Flows.
What is an event in a business process?
Events are something that happen and may have impacts on a business process. An event can be either external or internal. As long as they can influence the process being modeled, they should be modeled. Events are shown as circles. In some cases, there are icons within the circles to represent the type of the event trigger.
Why should every process have a start event?
Every process should have a start event to show the beginning of business process. It allows readers to locate in BPD where the process begin. Moreover, end event is used to indicate where a business process completes and intermediate event is responsible for driving business flow based on the event it specifies.
What are the motivations for supporting business processes?
Aside from boosting efficiencies, other relevant motivations for supporting business process work include: From IT, financial services, insurance and manufacturing, to education, telecommunications, retail, computers and software, every company can benefit from improved business or organizational processes.
Is BPMN notation simple?
In this case, sticking to a handful of symbols requires less in-depth knowledge of BPMN, so the notation is simple. Conversely, these models can also be adjusted to be extremely detailed for IT and other technical stakeholders.

Participants
We already described how to use lanes to assign responsibility for tasks or subprocesses to different task managers. Lanes always exist in a pool, and the lane boundaries represent process boundaries from start to end. To BPMN, the pool represents a higher-ranking instance compared to its lanes.
Activities
So far, we have used only tasks of undefined types, though BPMN provides the opportunity to work with task types just as it does for event types. Primarily, task types are intended to model processes that are technically executable. Task types are applied infrequently in practice.
Gateways
Certain things can only be done under certain circumstances, so few processes always take the same course. In our simple example, we want to go into the details of cookery. Driven by hunger, we think about what we are going to cook today. We only know three recipes, so we choose one. We can either cook pasta or cook a steak or prepare a salad.
BPMN subprocess examples
You can see there are two cases of deconstruction in the process flow. The first is the “Sell” subprocess that is reduced to 3 tasks. The second is a “Call Activity”, which makes a call to a first-level process (a reusable process flow):
BPMN Subprocess Example: Event
An event subprocess is contained at a specific process level (a common subprocess), or in a top-level process (main process flow), and is actioned by triggers.
BPMN Subprocess Example: Ad hoc
Ad hoc subprocesses have the characteristic of not being connected to other elements of the process, and their internal elements are also not connected to each other.
BPMN Subprocess Example: Loop
In this case, the subprocess will be flagged with an arrow, indicating that the subprocess is repeated until a particular condition is confirmed. If this occurs, the flow stops, or the subprocess restarts, similar to the behavior of a programmed loop.

Gateways
- Gateways are responsible for controlling how a business process flows. They are shown as diamond shapes. In a process, the work to do and the output may vary under different external or internal conditions. For example, a discount will only be offered to a VIP buyer but not to anyone else. Gateway is where conditions are evaluated and the decision is made. Here are some typica…
Sequence Flows
- Sequence flow is used to connect flow elements. It is shown in solid line with an arrowhead. It shows the order of flow elements. You can only use sequence flow to connect flow elements within the same pool: either within the same pool/lane, or across lanes in the same pool. If you want to connect elements across pools, you cannot use sequence flow but message flow instead.
Message Flows
- In BPMN, the communication between pools is achieved by the use of message. Message flow is used to show the flow of messages between pools or flow elements between pools. A message flow is shown in dotted line with an arrow head. Some examples of message that flows between pools: fax, telephone, email, letter, notice, command.
Case Study - The True Aqua Distilled Water Company
