Selecting a digital experience service provider is a complex and stressful task. In many cases, marketing teams select the service providers and oversee product selection, leaving IT to support and integrate technology solutions for which they don't feel ownership. But with the growing complexity of digital experience initiatives and the need to integrate legacy systems, marketing can no longer outsource everything and go it alone — application development and delivery professionals (AD&D pros) must get involved. For this report, Forrester examined the background and capabilities of nearly 50 vendors with significant digital experience implementation practices and developed a list of questions for AD&D pros to ask when searching for the right digital experience service provider.
