How well can we predict changes?

چکیده
Two years ago, we analyzed the architecture of Sagitta 2000/SD, a large business information system being developed on behalf of Dutch Customs. We were in particular interested in assessing the capabilities of the system to accommodate future complex changes. We asked stakeholders to bring forward possible changes to the system, and next investigated how these changes would affect the software architecture. Since then, the system has been implemented and used, and actual modifications have been proposed and realized. We studied all 117 change requests submitted since our initial analysis. The present paper address how well we have been able to predict complex changes during our initial analysis, and how and to what extent the process to elicit and assess the impact of such changes might be improved.
