Enterprises cannot achieve great customer success, digital disruption, and long-term growth and profitability without the right approach to core enterprise applications. To thrive, application development and delivery (AD&D) pros must foster a digital operations strategy that is "future fit" — to yield adaptivity, creativity and innovation, and ultimately sustainable business results (i.e., "resilience"). This playbook overviews why it's time for a new approach to back-office apps and how to use digital operations platforms (DOPs) as the foundation for your business success. This is an update of a previously published report; Forrester reviews and updates it periodically for continued relevance and accuracy.
