The age of the customer means that a focus on the customer now matters more than any other strategic imperative. Forrester's CRM playbook outlines four steps that application development and delivery (AD&D) professionals should follow to transform customer-facing business processes to deliver differentiated customer experiences: 1) discover the value of CRM; 2) plan the right strategy; 3) act to execute the strategy with precision; and 4) optimize your results. This is an update of a previously published report; Forrester reviews and updates it periodically for continued relevance and accuracy.
