This document discusses enterprise mobile development and selling apps to large enterprises. It notes that mobile app architecture should balance cost, capability and usability, with a preference for mobile web over hybrid or native apps. Most enterprise apps will access enterprise data and focus on employees, but some will target consumers. Innovation opportunities exist in leveraging mobile context like location. Selling to enterprises requires solving real problems, offering security, supporting multiple platforms and authentication methods, internationalization, appropriate licensing, and being open to testing and modification. Engagement can occur via conferences, publications, research services, or working for the enterprise directly.
