Study Notes

Master's in Computer Science and Business Management: Process Modelling and Deployment

  • The course is offered by Instituto Universitário de Lisboa (iscte).
  • The course covers process modelling and deployment.
  • The professor for the course is José Cascais Brás.

BPMN Modelling Constructs

  • The presentation covers BPMN (Business Process Model and Notation) modelling constructs.
  • BPMN icons are used to model business processes.
  • These icons convey specific meanings when used together.
  • The diagrams using BPMN icons can be used to build phrases and are used to visually represent how different parts of a process are interrelated.
  • The diagrams use icons for activities, events, gateways, and message flows.
  • Examples of BPMN uses are shown in the slides, including the creation of a flowchart for an application process.

BPMN Icons (Modelling Constructs)

  • BPMN icons represent various elements of business processes.
  • The icons include tasks, gateways, events, and message flows.
  • Different types of tasks (like manual, service, script, etc.) and events (like start, intermediate, end) are visually represented.
  • Data objects and swimlanes are also included in the model constructs to visually demonstrate flow paths, and roles involved.

Best Practices and Common Mistakes

  • The presentation discusses best practices in BPMN modelling.
  • Common mistakes in BPMN modelling are also highlighted for avoiding them.
  • Example violations of best practice are shown and explained.
  • Naming conventions for start, activity/task, and end events are discussed, showing good and bad examples of naming in BPMN process diagrams.
  • Best practice and common mistakes examples are presented.

Process Execution

  • The presentation covers technology used in executing business processes.
  • The execution of business processes is discussed with explanations of BPEL technology.
  • BPEL (Business Process Execution Language) is a language used to specify the implementation details of business processes.
  • BPEL is focused on the executable details of business processes
  • BPEL does not contain graphical elements, in contrast with BPMN diagrams.
  • Several tools, such as Apache ODE and Oracle BPM, support BPEL execution.
  • The relationship between BPMN Modelling and BPEL process execution is clarified.

BPMN Model Serialization

  • BPMN model serialization is used to interchange data between tools or processes.
  • Serialization formats include XPDL and XMI.
  • XPDL (XML Process Definition Language) is a standard used to represent BPMN diagrams, allowing other tools to exchange relevant details about a process.
  • XMI (XML Metadata Interchange) is a standard used to exchange information about the elements of a model.

Signavio Import/Export Options

  • Signavio offers import and export of various file types, allowing the interchange of data between different modelling tools.
  • The tools import and export various types of processes.

XPDL (XML Process Definition Language)

  • XPDL is an interchange format used to store BPMN diagram data.
  • XPDL supports different BPMN versions, showing the capability to use for model interchange.
  • XPDL is used by applications like Bizagi.

Standards Timeline - Releases

  • The presentation displays a timeline of releases for BPMN and XPDL standards.
  • The chart demonstrates the evolution of the standards.

XMI (XML Metadata Interchange)

  • XMI is a standard used for exchanging BPMN model data.
  • It includes the information about process graphics and semantics.
  • The tool that is used is Enterprise Architect.

Process Execution Technology: BPEL

  • BPEL (Business Process Execution Language) is an XML-based language
  • It specifies the exact implementation details of a process (what to do and how to do).
  • It is used in many process and workflow management tools.
  • The focus of BPEL is solely on execution logic.

Mapping from BPMN to BPEL

  • The presentation includes an example mapping from a BPMN diagram to a BPEL implementation.
  • The example shows the mapping logic needed to implement a process in BPEL.
  • The process is represented in a flowchart with different activities.

Common Modelling Mistakes

  • Several common modelling mistakes are shown with explanations.
  • Incorrect usage of Sequence Flows are shown.
  • Improper Lanes in a BPMN Process is also described.
  • Additional examples of common mistakes are illustrated.

Common Best Practices Violations

  • Several examples of best practice violations are shown in BPMN process diagrams showing how the best practices can be applied to create better models.
  • Avoiding implicit events or mixing different types of gateways are some examples.

Additional Examples

  • The examples given in this section are for modelling different processes.
  • Common processes like home pizza ordering, medical consultation and incident management are discussed to demonstrate how they can be modelled in BPMN.

Order to Delivery (Bottom-up Approach)

  • A bottom-up approach is used for modelling the order to delivery process.
  • This approach is beneficial in identifying tasks, their relationships and capturing the common meaning of the activities.

Order to Delivery (with Subprocesses)

  • This presentation shows how to create a better process diagram by adding subprocesses to the diagrams.
  • It explains how these steps are represented using subprocesses in a way that simplifies the diagram and improves its readability.

Order to Delivery (Top-down Approach)

  • The diagram shows a top-down approach to creating the order to delivery process.
  • The approach is beneficial because it shows the process from a high-level perspective to provide the overall details and flow path.
