IBM Cognos Analytics has positively impacted my organization by reducing report formulation time by 60%, especially for templated recurring reports such as the monthly sales report.

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.

In my opinion, IBM Cognos is very stable, and the benefits of choosing it, aside from cost savings, include having institutional knowledge for maintaining this infrastructure and a reliable solution that enhances developer productivity, given our team's extensive experience with IBM Cognos.

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.

When it comes to decision-making, the product is very useful and used in many departments since a lot of people prefer the reports to be generated by IBM Cognos.

The main difference that I like about Cognos compared to other solutions is its data splitting functionality. We have all our company data inside the Cognos environment and so we prefer to split the information Cognos itself. It's more efficient this way.

The tool can join data from different sources, write back to databases, generate alerts, and be customized to our preferences. It's an enterprise BI tool that's more powerful than just visualization tools like Power BI or Tableau.

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.

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.

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 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.

I don't like that when we use Colab packages, we get less functionality. For example, you can make groups of data with Excel or with the data sets from the packages, but when you use the Colab packages directly, you can only group the data when you analyze it with Analysis Studio. I think Cognos needs to improve more on this functionality.

I need improvements, particularly with the Framework Manager, which has an outdated user interface from older versions like IBM Cognos 10 or 8. Additionally, the Event Studio, which offered great flexibility in previous versions, is no longer available in IBM Cognos Analytics 12. These are areas that could be improved to enhance the product.
