Welcome to the 16th door of our MBSE Podcast Advent Calendar. Today, we take a look at the modeling of a sequence diagram. 

A sequence diagram depicts the exchange of messages between properties represented by the so-called lifelines. 

Let’s look at it in our model. 

Our sequence diagram shows a simple scenario of our MBSE Podcast Christmas Tree. Actually, the tree does not include so many scenarios. Well, it is just a tree. 

The model element represented by the whole sequence diagram is called an interaction. Here, the interaction is owned by the system context element. 

The user sends a switch-on signal to the enjoyment control unit. It is an asynchronous message. Then, the internal operation startFlashingProgram is called, which starts a loop to switch on and off the fairy lights, and in parallel, the lights enjoy a child. 

You can use sequence diagrams for several purposes, for example, to specify a test case, to specify a communication protocol, to demonstrate an example, and so forth. 

So much for the 16th door of our MBSE Podcast Advent Calendar. We wish you a great 16th of December.
