Collaborative Architecture Design and Evaluation

In this paper we describe a collaborative environment created to support distributed evaluation of a complex system architecture. The approach couples an interactive architecture browser with collaborative walkthroughs of an evolving architectural representation. The collaborative architecture browser was created to facilitate involvement of project stakeholders from geographically dispersed, heterogeneous organizations. The paper provides a rationale for the approach, describes the system created to facilitate distributed-collaborative architecture evaluation, and reports on evaluation results from an ongoing, very-large scale application integration project with the United States Marine Corps. The paper contributes to research on early architecture requirements engineering, architecture evaluation, and software tools to support distributed-collaborative design.
