Hi all, I have searched the forum, the Capella help at the two locations and Pascal’s and Jean-Luc’s books on the subject and cant find anything. So asking here…
I am just working at the System Analysis layer currently and running Capella 1.4.2.
I would like to contextualize a SAB diagram against the capability. When i try to do so the capability cannot be selected, only the functional chains, modes/states and exchange scenarios. Am I missing something or is this intended as not possible?
The reason for this is that I am approaching a requirements review design gate. I have created various capabilities expressing the high level objectives of the system and expressed these through functional chains and exchange scenario diagrams. I would like to show the contextual SABs and ES diagrams to explain each capability in engineering reviews to validate the requirements before the formal design gate. Using capabilities to organise the information is really useful. Contextualizing the SAB against the whole capability would be the easiest way of doing this.
I do have multiple functional chains for each capability. Is this wrong and making this more complex that it needs to be? The system I am designing is mechanical,electrical and electronic so for example; I have a functional chain relating to the flow of high voltage power through the system, separate to the functional chain relating to the control aspects, under one capability. Should I really be combining these functional chains such that there is only one per capability? Or is my approach ok? Sometimes the functional chains are shared by multiple capabilities. For example the flow of power through the system (which i have as its own functional chain) is used by multiple capabilities with different functional chains related to the control aspects. This helps when making new SDFB for each capability as I can use the functional chain modelling accelerators. Hopefully that makes sense!
Would appreciate any advice on either the way I am am using functional chains or the specific question about Contextualizing the SAB against a Capability.
