Currently, many software-development organizations have adopted a work methodology around global software development in which the members of a geographically dispersed team can coordinate their activities through collaboration tools. These tools focus primarily on the construction process rather than on concrete design. This kind of organization usually has teams in which members are located in different cities or even in different countries. As a result, architects must attend face-to-face meetings where they can define the architecture together. To tackle this challenge, we developed Archinotes, a tool to support approaches to global agile-architecture design. Using this tool, architects can coordinate, communicate, and control an agile software-architecture design process while being geographically separated. In this presentation, we demonstrate the main features of Archinotes and present its main benefits for an organization with geographically dispersed teams.
