We've travelled this road before. EDA is not an implementation 
approach, IMO. A melding of SOA and EDA in an architecture definition 
doesn't render EDA an implementation detail. Event analysis at the BA 
level can be very useful. The services can definitely provide 
additional context/boundaries--but so too does a BA that uses some 
functional segmentation other than SO. Identifying services can help 
identify important events. Identifying important events can help 
identify services.
