IBM Cognos Query Studio is an ad-hoc querying and reporting tool for creating simple lists in IBM Cognos Analytics. IBM Cognos Analysis Studio is a dimensional analysis tool for exploring, analyzing, and comparing dimensional data. IBM Cognos Workspace allows users to assemble dashboards using existing report parts. All studios were designed and implemented prior to Cognos Analytics 11 version.
To simplify our offerings and to provide better self-service user experience, Cognos Analytics 11 introduced AI infused interactive dashboarding and delivered major usability improvements in enterprise reporting. As such, Query Studio, Analysis Studio and Cognos Workspace have not been enhanced since Cognos 11 and we have no plan to further improve these legacy components. Their conformance level will remain unchanged.
IBM Cognos Analytics with Watson version 11.2.4 (long-term support) is the final release that includes IBM Cognos Query Studio, IBM Cognos Analysis Studio, and IBM Cognos Workspace. See announcement letter here.
We recommend customers to migrate their users and workloads to modern components such as Cognos dashboards and reports. Feature comparison documents are available to help customers to further understand how to leverage modern capabilities to perform equivalent BI tasks.

As a reminder, Query Studio and Analysis Studio assets do continue to render automatically in Cognos report viewer without recreation. Assets can also be manually converted to Cognos reports for future modifications. We have also developed a feature to allow customers to convert assets in bulk.
