With the advent of BPMN 2. Design patterns describe best practices for specific situations. Modeling guidelines guide and influence process modelers to use best practices for process modeling. It must be noted that the alternatives differ in their data handling if they are executed in process engines. USA Simulation is a traditional analysis technique in operations management. It is a branch or trunk in the tree-structure hierarchy of Process activities. N Normal Flow A flow that originates from a Start Event and continues through activities on alternative and parallel paths until reaching an End Event.

Figure 3 shows the structured and symmetric process model. It must be mentioned that certain situations cannot be captured symmetrically.

Notice that every opening gateway has its corresponding closing gateway. The next two figures present a scenario that is modeled in a structured and an unstructured way. Two Customized Artifacts Modeling Styles The category of modeling styles contains rules that are generally known and accepted.

BPMN-2.0-Handbook-Camunda.pdf

In such cases process models incorporate unstructured parts. A process model is structured and symmetric if every split gateway has a respective join gateway of the same type.

Modeling Styles — Examples In order to illustrate the use of general modeling styles we propose three examples and explain them in detail.

This modeling style leads to formations in process models that are known as blocks. These rules apply to all modeling projects. The styles assist process modelers by guiding them with general instructions on how to create process models more effectively.

Modeling styles influence the modeling behavior of modelers which often leads to an increase in the comprehensibility of process models. Modeling styles restrict the freedom of process modelers to draw models as the modelers must apply the style definitions. Empirical studies showed that people have difficulties to understand unstructured process models because they expect every split gateway to match its respective join gateway.

Modeling styles are also not dependent on actual modeling goals and purposes. Process models that incorporate block structures are easier to understand due to their increased comprehensibility. General layout styles should be applied to all modeling projects. The limit depends on a number of factors. The size of process models is thus directly connected to the understandability and error probability of a process model.

Process models should only contain elements that focus on the control flow in the model or those that add value to the model. The third modeling style advices modelers to use a few elements as possible in process models.

Layout Styles The layout of process models is important when it comes to read and comprehend the model content. Layout styles restrict this freedom by enforcing rules that define how process models should be visualized.

Large models should be decomposed into smaller ones with the help of sub-processes. Layout styles can be divided into two groups: Empirical studies showed that the larger a model the more difficult it is to understand.

There should be no superfluous elements in models. Layout rules do not change the graph structure of process models so that the semantic meaning of them remains the same. Modeling notations do not define how to place elements within process models. Models with improved layouts are easier to read than those whose layouts are obfuscated by means of visual cues.

Although the modeling style sounds trivial. Modelers are generally free to place symbols anywhere within the modeling canvas. Layout styles define rules that influence how modelers draw process models. Optional layout styles are recommendations to further improve visual representations. Structured Process Model Caption 4: Unstructured Process Model The second modeling style limits the number of elements in process models.

This style is based on similar reasons as the second one. All representations are semantically equivalent but they differ in placing the flows. Although it advises to use only one representation within a single process model.

Incoming sequence flows should enter a symbol from the left. Figure 6 shows several but not all ways for connecting two symbols with a sequence flow. In practice there are a number of rules in both categories. For this optional layout style we recommend the following two rules. To illustrate the use of layout styles. Caption 5: Representation of the Exclusive Gateway An optional layout style is to enforce rules for the drawing of sequence flows between symbols.

Enforcing this general layout style leads to the harmonization of process models with respect to this visual cue. Process modelers are free to choose the way to draw the flows. Organizations should introduce general as well as optional layout styles to control and harmonize the visual representations of process models to increase their comprehensibility. One general style concerns the representation of the exclusive gateway XOR. In practice this can lead to different layouts which might confuse model viewers.

The specification allows the user to draw the gateway with and without an internal marker. Layout Styles — Examples In the following two examples for layout styles are shown. In modeling projects where a large number of models is created. If there are no rules or recommendations.

The event handling in Figure 7 runs in the scope of the main process. In order to govern situations where alternative process models represent the same information. Although the representations differ. Organizations should focus on one alternative and enforce it in all process models if possible. The differences occur due to the freedom of process modelers to use symbols from the given symbol set and to connect them according to the underlying syntax. It has full access to the data used by the sub-process.

Process modelers must be aware of these details and take appropriate actions. The best practices guide process modelers to choose the best representation for specific situations. The second one shows alternatives for the modeling of conditional flows. It describes the alternatives and recommends the best one for a specific situation. The recommendations can be used in several contexts. The event is triggered by an external event. The modeling guideline should definitely point out these details to advice the readers.

Figure 8 displays the same situation but uses different BPMN 2. The figures shown below are identical with respect to usability as sub-processes are not marked as call activity. With respect to reusability. In Figure 8 the event sub-process runs in the scope of the sub-process. If modelers use different symbols. In Figure 8 an event sub-process is modeled which starts the event handling if it is triggered by the external event.

The category of modeling alternatives presents those best practices. The mapping often leads to different representation of the same situations. The first example deals with non-interrupting message events. If sub-processes are marked as call activity. Modeling Alternatives — Examples In order to illustrate the concept of modeling alternatives two examples are given.

Figure 7 depicts a sub-process that has a non-interrupting intermediate event attached to its boundary. It must be noted that the alternatives differ in their data handling if they are executed in process engines. Both alternatives are identical from a control flow perspective. Especially in large projects with a lot of modelers the representations for one situation usually differ. It is advisable to use the alternative shown in Figure 9 as this version is easier to comprehend.

Both situations are semantically equivalent if the conditional flows in Figure 10 incorporate the same conditions as in Figure 9. For each path a condition is attached and shown as small diamond leaving the task A. The gateway decides on the path that is activated based on the outcome of the decision.

The same situation is modeled differently in Figure Figure 9 depicts a common decision using an exclusive gateway. The decisions to activate the outgoing paths are made separately with the help of two conditions. Organizations should choose this alternative and enforce it for all process models.

The first example focuses on the modeling of a meeting where several people participate. Design Patterns — Examples Design patterns are applicable for specific contexts.

In total. Best practices are especially useful at the beginning of modeling projects. Design pattern rely on these contexts or situations. Although the context seems trivial. They show the most intuitive and comprehensible version to model. They help novice modelers to become familiar with process modeling. These additional roles are shown as customized artifacts and associated with the meeting. With the help of design patterns organizations influence and improve the way modelers capture situations in process models.

The use of design patterns is illustrated in two examples. Figure 11 shows a design pattern to model such situations. Patterns can only be used if the real-world scenario matches the context of the pattern. Modelers must have modeling expertise to perform such checks. Design patterns describe best practices for specific situations. Exclusive Gateway Caption Implicit Decisions with Conditional Flows Design Patterns Design patterns are based on specific situations or contexts which should be captured in process models.

In certain situations design patterns are also applicable to other contexts. The pattern for business rules can be applied to similar situations where rule tasks are applied.

Caption Modeling Meetings Another example for a design pattern is the use of business rule tasks. The pattern can be reused for other meeting situations or collaborations. Another possibility to capture the meeting in a model is the creation of lanes for all meeting participants. Process models that explicitly capture rules in the model tend to get large and complex.

Modelers can represent rules explicitly in models as shown in Figure The task is marked as a business rule task as described in the BPMN 2. It must be mentioned that the container is not shown in Figure Summing up. It shows an effective way to capture the situation in the model. A better representation for business rules is shown in Figure The marking means that the rules are stored in an external container.

The pattern shown in Figure 13 is recommended to avoid these drawbacks. This representation requires a lane for each participant. This becomes especially important if processes contain several business rule tasks.

The model in Figure 13 is easier to read and comprehend than the one in Figure The naming usually relies on the process modeler and his naming style. The upper part of the figure depicts labels that can be understood well. Business Rules explicitly modeled Caption In order to add semantic information to symbols. The verification checks how well process models capture real-world scenarios. The labels of process elements are typically chosen according to their actual types.

It is advisable to propose naming conventions to guide the labeling of process elements. Naming Conventions — Examples Labeling process elements is an important feature. The quality assurance of name tags is important for verification tasks.

The lower part illustrates the same element types but shows labels which should be avoided. The standardization of name tags assists the governance of models. Name tags of tasks differ from those of events. Organizations should describe how labels for elements are chosen. The verb-object style is known to be less ambiguous and easier to understand. Figure 14 shows how labels for different process elements can be chosen. The semantic information given by labels is important when it comes to the verification of process models.

The labels of tasks are chosen with the help of the verb-object style. This style enforces modelers to choose a verb together with a business object. Naming conventions describe the styles to propose labels for different element types.

Best practice examples guide process modelers to create models that meet agreed specifications. This avoids misinterpretations especially at the beginning of modeling projects.

The content of the categories should be proposed by the organization and process modelers involved in the project. The framework is suitable to establish guidelines that meet the individual purposes of modeling projects. Best practice guidelines should be individually developed for modeling projects. The categories guide the development of best practice guidelines.

Best practice guidelines should also be updated if new best practices arise or existing ones change due to projectspecific requirements. It is important to tailor best practices to the unique purposes of process models and the project roles involved.. The introduction of modeling guidelines enables organizations to govern and manage process models as well as process modeling more efficiently.

The introduction of modeling guidelines should be done by expert modelers who do have large expertise and experience. We suggest to define modeling guidelines before the actual modeling in projects takes place. Along with the categories you should focus on your individual modeling project and collect best practices to meet your goals. Existing guidelines for BPMN 1. The categories capture characteristics of modeling projects that influence the modeling behavior and. Best practice guidelines for BPMN 2.

Especially novice modelers are supported by modeling guidelines. Of course. Each modeling project has its own characteristics. Modeling projects can largely differ in their purpose.

In this paper we presented a framework to develop best practice modeling guidelines. In order to develop best practice guidelines you can use the framework described in this paper. Best practice guidelines further assist the validation of process models which in turn helps to avoid semantic problems in models.

Guidelines should contain best practices that fit the purposes and goals of the actual projects. The management and enforcement of best practice guidelines plays an important part in modeling projects. If they do so. If organizations introduce best practice modeling guidelines for their modeling projects.

His focus is on process modeling with BPMN. Gerardo consults to customers on modeling approaches and prepares processes for technical implementations in process engines. Matthias is actively involved in BPM projects in different industry sectors. Gerardo applies BPMN in a number of customer projects.

He focuses on the development and application of BPMN modeling guidelines in customer projects. He is also founder of "BPM-Netzwerk. No Magic Inc. Acknowledgements BPMN 2. KnowGravity Inc. White Frank Leymann In addition the following persons contributed valuable ideas and feedback that improved the content and the quality of this specification: Workflow is a. It defines only the executable aspects of a process.

Users need to go beyond the vendor lock-in. With XPDL. This release includes all new functionality that was submitted to the working group and accepted by the working group. BPEL does not define the graphical diagram.

For additional information: XPDL provides a file format that supports every aspect of the BPMN process definition notation including graphical descriptions of the diagram. XPDL 2. BPEL is an "execution language" designed to provide a definition of web services orchestration.

How you store and interchange those process definitions is outside the scope of the standard. Also included is new functionality to update the BPMN to version 1. This is the only way to provide for a "round trip" through multiple tool and still be able to return to the original tool with complete fidelity. As a greater percentage part of the organization starts to use process tools for everyday work. But the BPMN standard defines only the look of how the process definition is displayed on the screen.

Atomic Activity An activity not broken down to a finer level of Process Model detail. The types of activities that are a part of a Process Model are: Compensation Flow Flow that defines the set of activities that are performed while the transaction is being rolled back to compensate for activities that were performed during the Normal Flow of the Process. Artifact A graphical object that provides supporting information about the Process or elements within the Process.

Abstract Process A Process that represents the interactions between a private business process and another process or participant. In a Choreography there is no central controller. Business Process Management The services and tools that support process management for example.

An association is represented as a dotted graphical line with an arrowhead to represent the direction of flow. It is a branch or trunk in the tree-structure hierarchy of Process activities. B Business Analyst A specialist who analyzes business needs and problems. It includes the flow and use of information and resources.

An activity can be atomic or non-atomic compound. Association A connecting object that is used to link information and Artifacts with Flow Objects. Compound Activity An activity that has detail that is defined as a flow of other activities. Business Process A defined set of business activities that represent the steps required to achieve a business objective.

It is a leaf in the tree-structure hierarchy of Process activities. BPM tools can eliminate manual processes and automate the routing of requests between departments and applications. Exception Flow A Sequence Flow path that originates from an Intermediate Event attached to the boundary of an activity. In a Process. Exception An event that occurs during the performance of the Process that causes a diversion from the Normal Flow of the Process. Flow Objects are Events.

Also known as "Or-Split. An End Event can have a specific Result that will appear as a marker within the center of the End Event shape. An Expanded Sub-Process is displayed as a rounded rectangle that is enlarged to display the Flow Objects within. The Process does not traverse this path unless the Activity is interrupted by the triggering of a boundary Intermediate Event an Exception.

Also known as "AND-Split. F Flow A directional connector between elements in a Process. End Event Results are Message. This can be one activity or a group of activities in an expanded Sub-Process. In terms of Sequence Flows. Flow Object A graphical object that can be connected to or from a Sequence Flow. An Intermediate Event affects the flow of the process by showing where messages and delays are expected. In a Choreography. The term Flow is often used to represent the overall progression of how a Process or Process segment would be performed.

Exceptions can be generated by Intermediate Events. D Decision A gateway within a business process where the Sequence Flow can take one of several alternative paths. Fork A point in the Process where one Sequence Flow path is split into two or more paths that are run in parallel within the Process. Choreography Activities.

A Pool is not required to contain a Process. Lanes are often used for such things as internal roles e. A Message Flow is represented by a dashed lined. A message is transmitted through a Message Flow and has an identity that can be used for alternative branching of a Process through the EventBased Exclusive Gateway.

If Pools are used. BPMN N Normal Flow A flow that originates from a Start Event and continues through activities on alternative and parallel paths until reaching an End Event. An Intermediate Event is displayed as a circle.

Participant A business entity e. No synchronization is required because no parallel activity runs at the join point.

Process A sequence or flow of Activities in an organization with the objective of carrying out work.. Participants are informally known as "Pools..

R Result The consequence of reaching an End Event. In BPMN. Types of Results include Message. A Lane extends the entire length of the Pool either vertically or horizontally. Also know as "OR-Join. In a Collaboration.

Also known as "AND-Join. The Sub-Process can be in a collapsed view that hides its details. Each Flow has only one source and only one target. Sub-Process A Process that is included within another Process. Triggers are associated with Start Events and Intermediate Events and can be of the type: Token A theoretical concept that is used as an aid to define the behavior of a Process that is being performed.

A Sequence Flow can cross the boundaries between Lanes of a Pool but cannot cross the boundaries of a Pool. U Uncontrolled Flow Flow that proceeds without dependencies or conditional expressions. Start Event An Event that indicates where a particular Process starts. A Sub-Process can be in an expanded view that shows its details within the view of the Process that it is contained in. BPMN has two different types of Swimlanes.

The Start Event is displayed as a circle. Swimlane A Swimlane is a graphical container for partitioning a set of activities from other activities. Transaction A Sub-Process that represents a set of coordinated activities carried out by independent.

A Task object shares the same shape as the Sub-Process. Trigger A mechanism that detects an occurrence and can cause additional processing in response.

A Task is used when the work in the Process is not broken down to a finer level of Process Model detail. The behavior of Process elements can be defined by describing how they interact with a token as it "traverses" the structure of the Process. This coordination leads to an agreed. A Sub-Process shares the same shape as the Task. Users seek more intelligent business process capabilities in order to remain competitive within their fields and industries.
