This document discusses strategies for managing corporate and personal devices in a heterogeneous environment. For corporate devices, IT owns and controls the devices, hardware, applications, and configurations. Systems are homogenous and enforced through policies. For personal devices, IT uses a "system of least control" with heterogeneous systems. Users have more control and access apps and data through self-service and app stores. The strategies aim to meet IT standards while empowering users and ensuring key constraints are applied.
