This exploratory paper addresses challenges related to aspects of the theme of CAISE 2025, “bridging silos.” That theme applies directly to low levels of synergy between entire academic disciplines and to similar issues involving different IS modeling traditions that encounter gaps between rigor and precision versus comprehension and usability by many IS stakeholders who lack advanced IT training. A work system perspective can address those issues by serving as an integrating nexus between disciplines and between IS modeling traditions while also bridging gaps between rigor and broad usability in IS modeling. The work system perspective provides a natural nexus at many areas of overlap between disciplines that focus on systems designed and operated to achieve goals. Other possibilities for bridging silos involving IS engineering traditions touch upon data, process, and software modeling.
