Its core strategy is to enable IT strategy to effectively support business strategy and clarify the relations between IT and business.

• IT system structure: including three aspects of application system, data and information infrastructure. Among them, data and infrastructure aim to support the application systems.

• IT control: including IT organization, processes of IT management and IT human resources. IT control is the content that has often been overlooked in the construction of IT system.
