For 2011, Forrester predicts that IT administration efficiency and business agility will become the main drivers for using identity and access management (IAM). A bevy of acquisitions during the past one to two years has created complex product portfolios and management interfaces. As a result, organizations will demand user interfaces that are more business friendly so that they can involve non-IT users in IAM processes even more. There will be tighter integration between data security and the identity life cycle. Along with the requirement to secure mobile devices with second factor authentication, this will drive both on-premises and cloud-based IAM implementations.
