Mobile development presents a completely different set of challenges from past enterprise development projects. These challenges aren't limited to development teams. They permeate all aspects of the software development life cycle (SDLC), enterprise architecture, and the methodologies you use to develop and deliver mobile applications. This assessment report for application development and delivery (AD&D) professionals outlines the elements of mobile AD&D, and the associated self-assessment tool helps determine organizational readiness for them. This is an update of a previously published report; Forrester reviews and updates it periodically for continued relevance and accuracy.
