Your role as a business architect is to use business architecture, such as capability modelling, to show the business impact of different priorities, for the purpose of enabling the business to make fact-based prioritarisations.

It is only a dilemma where true business architecture does not exist. If you had true architecture, you'd have process architecture. If you had process architecture you'd have an end to end framework in which investment and the delivery of the investment - through work - prioritised already. If however we are talking about something so micro as in what to do today, this marketing bit, or this finance bit, well it comes down to the criteria.
