Digital business leaders at banks must have both a vision of the future and a strategic plan for getting there. But moving from vision to action is never easy. Banks need a roadmap that lays out and prioritizes digital initiatives and that allows for course corrections due to unforeseen shifts in technology, customer behaviors, or other market realities. This report outlines what makes a dynamic, iterative digital roadmap that enables continual reassessment of initiatives based on customer needs, your org's tech architecture, and shifts in the wider ecosystem. This is an update of a previously published report; Forrester reviews and revises it periodically for continued relevance and accuracy.
