Technology leaders must help their firms engage customers consistently, along every step of their journeys — and constantly adapt and grow with their customer needs. To do this, they must deliver technical platforms that enable end-to-end integration and agility. This report outlines the four technologies required: digital platforms to project your business into new channels and customers’ lives; digital intelligence to develop a holistic understanding of customers; security through advanced Zero Trust and identity management; and infrastructure for business-based integration. This is an update of a previously published report; Forrester reviews and updates it periodically for continued relevance and accuracy.
