Toward a collaborative method for knowledge management of software architectural decisions based on trust

Design and implementation of Architecture is a knowledge-driven process. Evaluation and verification the knowledge, in order to ensure its quality, have important role in improving overall design process. Furthermore, Architectural decision making is a complex and multi-criteria decision making problem in which multiple stakeholders make decisions from their perspectives causing overlaps and conflicts in the adopted decisions. Therefore, the requirement for strategies to manage these issues and also to improve coordination and cooperation among the various stakeholders to improve the overall process design is necessary. In this regard, there have been several activities that focus on increasing the accuracy and reducing costs, but the coordination between multiple different criteria are not covered well. In this paper, presented a method for collaborative architecture knowledge management (KM) that use of trust for evaluation and verification new knowledge and also uses collaborative strategies. Proposed method helps collecting valid knowledge, increasing accuracy, and to reduce costs of architectural design. To evaluate effectiveness of the proposed method, we used ATAM evaluation method and results of the evaluation are provided.
