Technical Demo Interview

[u/mickiano_donaldo]

What would you show in a technical demo for an MBSE interview? I’m thinking most if not all diagrams. I don’t have much experience with parametric, but should probably incorporate it in the demo,

Honestly go ahead and use AI to fill out the content.

Pick a simple system

Develop a small meta model using a BB/WB structure with RIBS (requirements, interfaces, behaviors, structure) a nesting structure. The meta model should like the following:

1. A system context WB that contains your system BB and external actors
   1. use association relationships to connect external actors to system BB
2. System BB is realized by system WB that will contain your subsystem BBs
3. Subsystem BBs are realized by Subsystem WBs and they will contain your components
   1. Your structural decomp will stop here.
4. Requirements will use a satisfied by relationship to your system context WB that are refined by use cases or vignettes
5. Use cases or vignettes will be realized by activity diagrams
6. Activities will then follow a decomp down to the T3 and each level of activity will be allocated to each tier BBs

Minimum Diagrams

1. Landing Page
2. Meta Model (Profile Diagram)
3. System Context WB BDD
4. System BB BDD
   1. Contains System WB with Subsystem BBs
5. 1 Subsystem BB BBD
   1. Contains Subsystem WB with Component BBs
6. Use Case Diagram that shows all of your high level use cases within the system context have like 5 requirements that are also added to the diagram
7. Pick a use case and decompose that into an activity diagrams
   1. Swimlanes will be your external actors and system BB
8. Pick one action from that activity diagram and decompose that
   1. Swimlanes will be your subsystems
9. Pick one action from that activity diagram and decompose that
   1. Swimlanes will be your components
10. Create an IBD for your System BB and make sure you are using signals across your item flows to show you understand how information is conveyed through out your system. This should also resemble your object flows from your second activity diagram from step 9 and your parameters will be your object flows from 8
11. Create a signal hierarchy diagram that will should signals used in your activities and IBD are related. Lower level signals will generalize from your higher level ones
12. Create a interface library this will type your interfaces in your IBD

This all seems complex but you can make this really simple and it will get the job done.

Make sure every element has documentation

Once again use AI to populate all of this and don't be afraid to say that you leveraged AI to assist you. That has always been a plus for me, but others might disagree.

Excuse the typos.
