The positive impact of IBM Cognos on my organization is notable; previously, the reports we were using did not meet the expectations of our managers and heads of departments, often leading to criticism, and now we experience far fewer complaints from management, who are generally satisfied with the details of both high-level summaries and technical breakdowns when needed, enhancing our management efficiency.

We use the account statement report. When you use an account in HSBC, you receive various types of accounts, such as the stock market, fixed accounts, credit cards, and business accounts. We can create one consolidated report called CCS support, which includes all these accounts. In that statement, we are consolidating all those accounts.

Feb 10, 2026
I believe IBM Cognos can be improved by addressing its limited real-time data connectivity, as well as enhancing the endpoint experience and mobility, which currently is not satisfactory due to limited data blending.

We are generally satisfied, but I am not certain if IBM Cognos meets every feature request from users since we only provide IBM Cognos as our standard and do not maintain infrastructure for other tools.

IBM Cognos could be improved by integrating more with artificial intelligence.

Regarding improvements for IBM Cognos, I think nothing yet about functionality, but I find the costs to be quite high for the enterprise system.

IBM Cognos could improve by introducing different role types, such as viewer roles, user roles, and admin roles, along with assigning minor modules to specific individuals.

IBM Cognos can improve its error messages, as whenever something is wrong, it does not give us the proper error message, and we end up rebooting the entire software.

Compared to Tableau and PowerBI, the IBM interface is easier to use. However, the drag-and-drop functionality isn't as straightforward. Formatting is also more challenging in the cloud than in other applications, like Power BI. Also, if you encounter an issue, it takes more time to resolve it on the formatting side.

The tool needs to improve the connectivity since I see that, at times, there is a need to increase the memory in the database.
