BA Technique #42: Sequence Diagrams
Elaborating visual representations of interactions and message flows between different components or actors in a system.
Welcome, BAs! Today, we unravel the art of visual storytelling with Sequence Diagrams, another crucial Business Analysis technique from The BABOK Guide v3. Brace yourselves to capture the dynamic interactions and behaviours of system components. Business Analysts gain insights into system behaviour, communication flows, and potential bottlenecks by depicting the sequence of actions and messages exchanged. Let's embark on this visual journey!
What is this technique about?
Sequence Diagrams originated from software engineering and the Unified Modeling Language (UML), developed in the 1990s. They illustrate the order and flow of interactions between objects or components within a system.
In Business Analysis, Sequence Diagrams are an effective tool for modeling and analyzing complex systems and their interactions. It provides a structured approach to clearly define the extent and limitations of what is included and excluded in the initiative.
