When did BPMN Release?

By Tim Ackroyd on

The purpose of this post is to set up a conversation around Business Process Modeling (BPM), specifically Business Process Modeling Notation (BPMN) and Business Process Execution Language (BPEL). As we develop content for the UML Operator Channel related to Model-Driven-Architecture (MDA) and delivering Systems and Software, BPM is critical to understand and defining Project Delivery. So let's start with some history and then move into some nuances.

The Business Process Model and Notation (BPMN) specification was first released in the year 2004. BPMN is a graphical modeling language specifically designed for representing business processes and workflows in a standardized manner.

The initial version, BPMN 1.0, was developed by the Business Process Management Initiative (BPMI) and released in 2004. It provided a comprehensive set of symbols, rules, and semantics for modeling business processes, allowing organizations to visually represent and communicate their processes effectively.

Since its initial release, BPMN has gained widespread adoption and evolved through subsequent versions to address industry requirements and incorporate refinements. BPMN 1.1 was released in 2005, followed by BPMN 1.2 in 2006.

In 2008, the BPMN specification was transferred to the Object Management Group (OMG), which is also responsible for the UML standard. Under OMG's stewardship, BPMN continued to evolve, and in 2011, BPMN 2.0 was released.

BPMN 2.0 represented a significant milestone, introducing several enhancements and expanded capabilities over BPMN 1.x. It introduced concepts such as collaboration diagrams, expanded modeling elements, support for choreography modeling, and improved integration with other standards like UML.

Since the release of BPMN 2.0, there have been subsequent revisions and updates, such as BPMN 2.0.1, BPMN 2.0.2, and BPMN 2.0.3, which have provided clarifications, corrections, and additional features to the BPMN specification.

BPMN has become a widely accepted standard for modeling business processes, offering a common visual language that facilitates communication, analysis, and automation of workflows within organizations.

When did BPMN 2 Release?

BPMN 2.0 was released in the year 2011. It represented a significant update and expansion of the Business Process Model and Notation (BPMN) standard. BPMN 2.0 introduced several new features, enhanced modeling elements, and improved integration capabilities compared to its predecessor, BPMN 1.x.

The release of BPMN 2.0 was overseen by the Object Management Group (OMG), the organization responsible for maintaining and evolving BPMN. BPMN 2.0 aimed to address limitations and provide a more comprehensive and robust notation for modeling complex business processes and workflows.

Some of the key features and enhancements introduced in BPMN 2.0 include:

  1. Expanded Modeling Elements: BPMN 2.0 introduced new elements such as expanded event types, expanded gateway types, and collaboration diagrams for modeling interactions between multiple participants.
  2. Choreography Modeling: BPMN 2.0 added support for choreography modeling, allowing the modeling of message flows and interactions between different participants or business entities.
  3. Integration with Other Standards: BPMN 2.0 improved integration with other standards, including UML (Unified Modeling Language), allowing for a more seamless combination of modeling techniques for different aspects of software systems.
  4. Execution Semantics: BPMN 2.0 provided a more formal specification of execution semantics, enabling the execution and automation of BPMN models in business process management (BPM) systems.

Since the release of BPMN 2.0, there have been subsequent updates and maintenance releases, such as BPMN 2.0.1, BPMN 2.0.2, and BPMN 2.0.3. These updates have provided clarifications, corrections, and minor improvements to the BPMN 2.0 specification.

BPMN 2.0 has become the widely adopted version of the BPMN standard, serving as the de facto notation for modeling business processes and workflows in various industries and organizations.

When Did BPEL Release?

BPEL (Business Process Execution Language) was first released in the year 2003. BPEL is an XML-based language used for specifying and executing business processes in service-oriented architectures (SOA).

The initial version of BPEL, known as BPEL 1.0, was developed as a joint effort by several companies, including IBM, Microsoft, and BEA Systems (now part of Oracle). It aimed to provide a standardized language for describing business processes that can be executed in a distributed and interoperable manner.

BPEL 1.0 defined the syntax, semantics, and execution model for representing business processes as a series of interconnected activities. It allowed organizations to orchestrate and automate business processes by defining the sequence, conditions, and actions of individual activities using XML-based constructs.

After the release of BPEL 1.0, subsequent versions were introduced to address limitations, incorporate feedback, and provide additional features. BPEL 1.1 was released in 2003, followed by BPEL 2.0 in 2007.

BPEL 2.0 was a significant update that brought several improvements and new capabilities to the language. It introduced features like support for human tasks, event handling, and compensation mechanisms, enabling more flexible and comprehensive process modeling.

Since the release of BPEL 2.0, there have been subsequent updates and maintenance releases, such as BPEL 2.0.1 and BPEL 2.0.2, which provided clarifications, corrections, and minor enhancements to the BPEL specification.

BPEL has been widely adopted as a standard for modeling and executing business processes in SOA environments. It allows organizations to define, automate, and coordinate complex business processes involving multiple services and systems, promoting interoperability and scalability in enterprise integration.

BPMN vs BPEL

BPMN (Business Process Model and Notation) and BPEL (Business Process Execution Language) are two complementary standards used in the field of business process management (BPM). While they serve related purposes, there are important distinctions between the two:

  1. Purpose and Focus:
    1. BPMN is primarily focused on modeling and visualizing business processes. It provides a standardized notation for representing the activities, events, gateways, and flows within a business process. BPMN allows stakeholders to understand, communicate, and analyze business processes using standardized diagrams.
    2. BPEL, on the other hand, is an execution language designed for orchestrating and automating business processes. BPEL focuses on the technical implementation aspects of business processes, specifying the sequence, conditions, and actions required for the execution of a process. BPEL is used for integrating and coordinating web services in service-oriented architectures (SOA).
  2. Abstraction Level:
    1. BPMN operates at a higher level of abstraction, providing a business-friendly graphical notation. It allows business analysts and stakeholders to model and understand business processes using intuitive diagrams that depict the flow and structure of activities.
    2. BPEL operates at a lower level of abstraction, closer to the technical implementation details. It defines executable processes using XML-based constructs that describe the behavior and interactions of web services.
  3. Modeling vs. Execution:
    1. BPMN is primarily used for modeling and analysis purposes. It helps capture and document the business process logic, analyze process flows, and identify potential improvements or bottlenecks. BPMN models can serve as a communication tool between business and IT stakeholders.
    2. BPEL focuses on the execution and automation of business processes. It defines the behavior and execution logic required for the integration and orchestration of web services to achieve end-to-end process automation.
  4. Integration:
    1. BPMN can be used as an input for process execution, but it does not specify the detailed implementation of services or the execution environment. BPMN models can be translated into executable formats or used as a blueprint for process implementation in BPEL or other execution languages.
    2. BPEL is specifically designed for the execution of business processes. It provides a standardized language for orchestrating web services within an SOA environment, ensuring interoperability and enabling automated execution of process logic.

In summary, BPMN is focused on modeling and visualization of business processes, while BPEL is an execution language used for implementing and automating business processes within a service-oriented architecture. BPMN provides a business-friendly notation for process modeling, while BPEL defines the technical details required for process execution and integration with web services. Both standards play complementary roles in the BPM lifecycle.

Sparx EA and Open Collaboration

By Tim Ackroyd on
I get asked, quite often, "Is there a way to integrate Sparx Enterprise Architect (EA) with other tooling?" My answer is always, "Yes". There are multiple approaches, from very simple to more advanced. I have helped several shops do this over the years, and may do videos on this in the future. Integrating Sparx with Azure DevOps and other Cloud platforms, as well as other Tooling, is very possible and beneficial for managing delivery, such as requirements, problem solving, design, and development... all in a unified way.  The integration can allow companies/shops to seamlessly synchronize between Sparx EA's modeling environment and platforms, such as Azure DevOps'. Remember that one of the biggest benefits of Sparx EA over other modeling platforms, is that Sparx is based on Data-First implementation and supports open integration. Years ago, something call Open Services for Lifecycle Collaboration (OSLC) came out and Sparx was one of the first to embrace it. ...

BPMN Diagram versus Sequence Diagram

By Tim Ackroyd on
I am getting some great questions in our  UML Operator Channel , as we are publishing  a series on Business Process Modeling Notation (BPMN) . Modelers see the term "Sequence" in BPMN and get a little confused...probably my fault 😏. When using BPMN, just understand the difference between Unified Modeling Language (UML) and BPMN (an extension of UML) and things should fall into place. So now let's talk about BPMN vs UML Sequence Diagrams... BPMN Diagram versus Sequence Diagram BPMN diagrams and sequence diagrams are both types of visual representations used in the field of business process modeling and software engineering, respectively. While they share some similarities, they serve different purposes and focus on different aspects of a system or process. BPMN Diagram: Purpose: BPMN (Business Process Model and Notation) is used for modeling and documenting business processes. It provides a standardized way to r...

MDA vs MDD

By Tim Ackroyd on
This post kicks of a new series on UML Operator Channel  UML Operator Channel around systems and software delivery, titled "Model-Driven Anything". Subscribe, turn on notifications, follow, and most importantly...Contribute 😎 IMPORTANT NOTE: Never start a software development effort without Requirements!!! or Scope!!! However, sometimes software starts out as a means of developing scope and requirements! So what are we talking about? Model-Driven Architecture (MDA) and Model-Driven Development (MDD) are both approaches within the realm of software development that emphasize the use of models as primary artifacts in the software engineering process. However, they have distinct focuses and methodologies. Here are the key differences between the two: Model-Driven Architecture (MDA) Origin and Standardization: Origin: MDA is a software design approach proposed by the Object Management Group (OMG). Standardization: It is a well-defined framework with standardized guidelines and...
