Many software applications are now built from services which run on heterogeneous platforms and are accessed by several users. These environments are in constant evolution. So application and services have to dynamically adapt in order to satisfy the quality of services required by the users. These systems called adaptive system should provide the ability to adapt the external and internal environment changes. As a critical part in self-adaptive system, adaptive software is a function of how well the software supports and adapts the changing environment, so it is important for developers to acquire the knowledge of user’s roles, task will affect software changing. In addition, programming adaptation facilities taking account the different situations that could happen is a difficult task. In this paper, we focus on the idea of task model as a representation to support software adaptation, including task model compression, task model construction, using task model to support software adaptation, and users interact with their computing environments in terms of high-level tasks.
