The development of systems for the Internet of Things (IoT) environment is challenging, because it deals with features such as self-adaptability and the dynamism of the environment. Furthermore, the traditional development approach based on design-time decisions is inadequate if we consider the number of devices and technologies involved, and the inability to treat unforeseen scenarios at development time. Therefore, the development of IoT systems requires the use of practices that allow adapting the behavior and structure of the system in a more flexible way. Approaches premissed on models and structures that describe behavior, such as policies and workflows, have been proposed in the literature to achieve self-adaptation. However, the existing approaches do not fully support the main requirements of an IoT environment or are coupled to the environment and technologies. Thus, we propose a decoupled support mechanism, called SUCCEEd, that allows the creation and execution of a sequence of actions in an IoT environment. We have evaluated our mechanism regarding coupling and performance. The results show that: (i) our mechanism is a good option for reuse once is decoupled from middleware platforms; (ii) the time used to adapt is less than the time used to perform functionalities; and (iii) the number of steps needed to adapt is minimal in a matter of time
