Let me start with a provoking question: Business architects create capability roadmaps and product managers create product roadmaps. What is the difference and which is more valuable for my business? If product managers manage all the products of a company, is there a need for business architects and capability roadmaps?
Some of us, who are practicing business architects and familiar with “Guide to the Business Architecture Body of Knowledge™” (BIZBOK® Guide), may find this question offensive. However, this could be a reasonable question from any senior business leader (particularly unfamiliar with business architecture and product management disciplines).
