In cases where little Business Architecture work has been done before, it is necessary to research, verify and gain buy-in to the key business objectives and the processes that the architecture is to support. This may be done either as a freestanding exercise, either preceding architecture development or as part of Architecture Vision.
In either case, the business scenario technique of the TOGA ADAM, or any other teeth that illuminated the Key business requirements and indicates the implied technical requirements for IT architecture can be used.
