Welcome to our MBSE Podcast Advent Calendar. Behind the 11th door, we take again a look at the functional architecture.

Yesterday we created the functional groups and today we look at the derivation of the first version of the functional architecture. 

Here comes the special learning gift of this Advent calendar snippet:

This step and other steps of the FAS method could be done automatically or assisted by the FAS plugin for MagicDraw which is provided by the Germany chapter of INCOSE – the GfSE. You can download the plugin for free from Sourceforge at sourceforge.net/projects/fas4md.

The functional groups are in a sub-package of the functional architecture package. 

For each functional group, we created a functional block and modeled a trace relationship between them. The functional block is also a stereotype specializing the block from the FAS profile. The relationships can again be best depicted in a matrix. 

Functional Blocks to Functional Groups Mapping

In the matrix, you can easily see that all functional blocks have exactly one relation to one functional group.

We created a root functional block that represents the whole functional architecture and created the composition structure as depicted in the block definition diagram. 

Functional Architecture Definition

The more interesting part of the functional architecture is depicted in the internal block diagram. We will cover that tomorrow. 

So much for the 11th door of our MBSE Podcast Advent Calendar. We wish you a great 11th of December.
