One of the ways that meta-design methodology, introduced into the DSS area by Moore and Chang, can be further advanced thanks to the DSS architecture approach. The seminal Sprague-Carlson DSS design paradigm (Data-Dialog-Modeling) underlies or underpins most discussions of DSS architectures. Research done by the authors for several Polish business enterprises in the 1980s indicated the need to extend the Sprague-Carlson architecture. Their proposed solution thus seeks to enhance the original meta-design DSS methodology. The paper aims to present the findings of the authors’ research efforts focusing on a solution which has been in effect for over a decade in large enterprises as well as in capital groups.
