ATAM-AR: ATAM-based recovery architecture method

Software architectures are considered one of the main assets within the software companies. However, within organizations, do not usually have adequate descriptive solution. With the aim of having that description has emerged an activity of recovering a software architecture whose main approaches are pointed out to a recovering model from the implemented information and the spreading, particularly the source code, tacit knowledge present in the development team. In this work it is shown as a method of evaluating architectures allows recovery from the tacit knowledge of equipment, allowing not only regain his description but its intention. To evaluate the proposal, it has developed a case study where the ATAM method is used to evaluate and recover the architecture of a file synchronization system in the context of different virtual learning platforms. The case has allowed showing how manages to get the descriptive architecture including its rationale.
