Experience with a New Architecture Review Process Using a Globally Distributed Architecture Review Team

We present in this paper our experience with applying a new architecture review process that uses a globally distributed review team to assess architecture risk of a complex mission critical system. The new architecture review process uses aspects of the checklist-based architecture review process and the operational scenario-based architecture review process. We present the architecture review process approach, a summary of the architecture under review and the detailed analysis of the most important operational scenarios. We conclude by presenting a summary of the lessons we learned using the new process.
