The invention discloses a method and system recommending expected function sequence for users. The method comprises steps of acquiring at least one user wish list comprising at least one user wish, separating the user wish list into a plurality of tasks, generating a task process graph according to use data of the user, generating a function process graph based on the user use data, task and function time sequence, determining an expected function sequence based on the user use data, the task process graph and the function process graph, and recommending the expected function sequence to the user. The task processing graph top point represents a task and importance of the task; and the function process graph top point represents the function and the importance of the function.
