(BA005) Business Process Modeling (with UML 2 and BPMN) (Click for PDF version)

Duration: 2 days
CDUs (Continuing Development Units): 14
BABOK Compliance: BABOK Release 3
Description: This is a hands-on practical workshop for the BA in business process modeling using workflow models and state-machine diagrams (Harel statecharts) to describe the sequencing of events within a process. Trainees step through a complex real-life case study, learning not only how to draw the diagrams but how and when to effectively use the techniques during a projects’ life cycle. Trainees learn how to use business process diagrams to model existing and to-be processes, to define workflow for business use-cases, to supplement the documentation of system use-cases and to define lifecycle rules for business objects. The course covers the most popular standards for business process modeling: UML 2 – a wide-spectrum standard that covers the complete IT project lifecycle – and BPMN – a standard specifically created for business process modeling that is gaining widespread popularity. Trainees will learn to employ UML activity diagrams and BPMN Business Process Diagrams (BPD) to model workflow as well as UML-state machine diagrams to analyze the lifecycle of key business objects. As a supplement, IDEF workflow conventions developed by the military are also included in the printed course material and may be optionally included in class-time instruction.

Why Attend this Course?


Interviews with business stakeholders can often lead to conflicting requirements regarding workflow:
Business process modeling is an effective way to illustrate these differences and to develop a consensus amongst stakeholders during follow-up interviews or JAD Sessions.

Workflow modeling is a key activity in process improvement:
The techniques provide an effective means of analyzing existing workflow and comparing proposed improvements.

Complex sequencing rules described by the BA are often misunderstood by developers:
The techniques in this course result in standardized visual documentation that cannot be misinterpreted by the development team.

The rules that determine how the business treats a business object over its lifecycle are often spread across the requirements documentation:
The state-machine modeling technique taught in this course results in a visual summary of the object’s lifecycle from the time the business becomes aware of it until it is no longer used. UML standardization means these requirements won’t be misinterpreted by the development team.

What Makes this Course Stand Apart?


Learn when to apply which techniques: The trainee learns not only what to do, but when to use each technique during the course of a project.

Integration with use-cases: We teach the trainee exactly how to integrate these modeling techniques with use-case analysis. Trainees learn at what steps during use-case analysis to create the workflow models and how these models fit into use-case documentation.

Experience: Our course is written and delivered by professionals with extensive practical experience in workflow modeling for IT business system within the context of use-case analysis.

Objectives


Upon completion of this course, you will be able to:
Define workflow rules for a business process.
Consolidate the viewpoints of stakeholders during requirements-gathering sessions using activity diagrams.
Describe business use-case workflow with activity diagrams.
Tie together system use-cases using activity diagrams with and without partitions (swimlanes) and object flows.
Augment system use-case documentation with activity diagrams.
Create UML state-machine diagrams that describe the life cycle of a business object.
Link use-cases to state-machine diagrams.
Convert activity diagrams to BPMN format (BPD).
Supplement: Convert activity diagrams to IDEF format
. (Included in course material; covered in lectures upon request.)
Supplement: Understand alternative approaches to the UML standard, including flowcharting, block diagrams and Data Flow Diagrams (DFD). (Included in course material; covered in lectures upon request.)
