We performed a comparison between IBM Cognos and Tableau based on our users’ reviews in five categories. After reading all of the collected data, you can find our conclusion below.
Comparison Results: In this comparison, IBM Cognos comes out on top. Users are happier with the support than Tableau users are, and IBM Cognos users also report an ROI.
"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."
"Security administration tools are powerful and flexible."
"The comprehensiveness or broadness of the software functions or business intelligence functions that it provides is valuable. It is also quite easy to use and user-friendly."
"The solution's most valuable feature is its ease of use, which makes it easily compatible with other tools."
"The three IBM Cognos features I find the most valuable are Dynamic Cubes, PowerPlay, and Watson."
"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."
"For planning, forecasting, in-boxing, modeling in general and for predicting numbers and doing work analysis, they are excellent."
"Comparing IBM Cognos to other applications, once a person is trained on it or they have developed a skill set to operate the application, it is best in its category."
"We frequently utilize visualizations using maps and different objects, all with rich coloring options. And tooltips are absolutely essential for us. Tooltips, like the pop-up descriptions when you hover over some object or graph. Those tooltips in Tableau are great features."
"Tableau has many good features. It is user-friendly, has a simple-to-use interface, and has a customizable dashboard."
"It has a shallow learning curve and so you can go to market very, very, very quickly."
"It's very easy to set everything up."
"Good data flow and management."
"The solution has great features which nobody can beat, you can do a lot of customizations, such as use different dimensions and colorize them. Additionally, you can use the numeric values for the customization, which is an exceptional feature."
"Show Me is a feature to help with knowing which chart is an appropriate one for the selected variables, and it makes helps in creating appropriate visuals."
"The number one thing was just the ease of getting something up quickly. The other thing that was good about it was that it was fairly fast for decent-sized data sets in terms of performance and run time."
"It would be better if it is was easier to implement without extensive training for it."
"I would like for the platform to become more standard. If we make a development on our report and our dashboard, it will not be used in another solution. That means there is no portability for the developers."
"Need improvement towards Visualization."
"Most of our company's customers want to be able to deploy IBM Cognos on a web application and use it as a desktop application, which is not possible currently."
"We need more predictive analytical functions, not only diagnostic or decryptic analytics."
"There are a lot of limitations with the out-of-the-box tool."
"I would like to have predictive and forecasting capabilities in Cognos. It's one thing to do reporting, and another thing to easily predict or forecast certain data points, which is very important for all the clients."
"One key area for improvement is the need to improve the self-service nature and functionality of the product in terms of visual analytics."
"Whenever it comes to specialized visualization, Tableau is an absolute failure."
"When it comes to large datasets, the data should be extracted faster."
"In the cloud sometimes the performance is a little bit slow."
"The performance could be better."
"It will be good if the server, could be more stable, and I would like to have the technical service to be more reliable."
"Its price should be improved. Its price is much higher than Power BI and QlikView. Programming is not easy on Tableau. For programming, you have to have a separate model. They should include programming directly on the web portion of the Tableau desktop so that people can write Python or JavaScript code for customizations instead of using a different model. Currently, Tableau Data Prep is a separate application that you have to purchase. It would be helpful if they can include Tableau Data Prep and programming languages such as R, Python in the next version. Tableau Public, which is a community version, doesn't allow you to save your work on your desktop. They should allow it. Currently, you can only upload it in the community."
"I am a BI consultant. I have worked on different reporting tools, such as Power BI and MicroStrategy. As compared to other tools, Tableau lags behind in handling huge enterprise-level data in terms of robust security and the single integrated metadata concept. When we connect to large or very big databases, then performance-wise, I sometimes found Tableau a little bit slow. It can have the single metadata concept like other tools for the reusability of the objects in multiple reports."
"At the organizational level, increasing the servers' capabilities to support us as an enterprise tool."
