Flows in MoSy represent the sequence of actions between actors and the system, showing how these interactions progress to achieve specific goals. Flows illustrate who does what, when, and how system elements respond, ensuring a structured, step-by-step visualization of processes. Examples of flows in an e-commerce system are Customer Checkout and Order Cancellation.
Flows help achieve business or system objectives, influencing key metrics. We’ll cover this in more detail.
The High-Level System View in MoSy does not yet zoom into Flows to detail the actions that compose them. Later, you will see how these are illustrated in the Flow Diagram.
You can use sticky notes if you’re doing this exercise in person (the best option) or little boxes in a diagramming tool. Add flow names between each pair of actors on top of an arrow representing who initiates the flow. For example, the customer initiates the Customer Purchase. The flow might involve these two and other actors, but this is a simple visualization that helps align who initiates the process and gives an overall picture of the different actors and interactions in the system.
