This document discusses the lifecycle approach to mobile application development. It outlines the key stages in a mobile app lifecycle: plan, build/connect, test, manage/release, and analyze. Each stage represents important steps, from requirements gathering and design in the plan stage to distribution, management, and analysis of usage in later stages. The document notes that as apps and operating systems increase in number, managing the lifecycle of mobile applications across their development and use has become more complex, requiring improved processes and visibility across roles.
