Interaction granularity issue between Business Architecture (BA) and Technical Architecture (TA)
There is Interaction granularity issue between BA and TA. We have just 1 or 2 Interactions documented in BA BIM diagram vs. multiple interactions at implementation level in Tech07, CBID and network diagrams.
We want to know the best practices on this. Do we need to have identical Interactions in TA and BA or use the BA interactions in TA and define the missing ones in TA.
