The most valuable feature of IBM Cognos is security. The solution has updated features that other competitors' solutions come out with long after IBM Cognos has had them.
IBM Cognos provides robust corporate reporting and analytics with an intuitive drag-and-drop interface. Security features and enterprise tools like Dynamic Cubes and Watson enhance data integration and analysis. However, improvements are needed in visualization quality and predictive analytics. Support issues, high costs, and performance challenges with dynamic queries affect scalability. Error handling for large datasets also requires attention to better compete with Tableau and Power BI.
