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.
"Even while a user is using a cube for reporting, there will not be a situation as ' Cube file locked; unable to build or deploy'."
"Cognos is the best application with dashboards,batch reporting, jobs, events and ad-hoc reporting for business users."
"Security administration tools are powerful and flexible."
"We use IBM Cognos for enterprise analytics and reporting."
"A drag-and-drop interface for selecting creating ad hoc reports makes this product very easy to use."
"Dashboarding, reporting, and ad hoc reporting are the valuable features of 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."
"Self-service is possible through the use of dashboards, which are also very intuitive. Stories can be used to pin snapshots, tell the story for meetings, etc."
"Tableau has greatly enhanced our organization's data-driven decision-making processes by enabling us to create visually compelling reports and dashboards."
"Tableau's most valuable features are user-friendliness and have a connection between multiple source systems. You can publish a report by using Tableau Public and there you can make your data online, not only batches of data, you can use it as an online analytical tool."
"The geospatial maps representation and the visualizations are nice."
"You are able to see and follow trends."
"From the data science point of view, we use it for model building purposes. For example, if we are using it for a bank and we want to understand how much loan the bank can provide, we can use visualization to show the educational qualification, salary, gender, and city of a customer, and by using this information, we can arrive at the loan amount that this person is eligible for. I can also use it to view all prospective customers, so essentially, this is going to help me in model building as well as in understanding and segmenting customers and doing forecasting and predictive analytics. We use model widgets, and we can create thousands of visualizations, such as motion charts and bubble charts. We can also create animated versions of the graphs and view the data from multiple dimensions. These are the features that we typically use and like."
"Data Interpreter: Which can identify issues or potential errors with your imported data."
"I like the solution's web version, more so than Power BI's web version. It just makes it easier to drag and drop things and to blend data on the backend. It simplifies the process."
"The solution helps users create dashboards and analyze data without relying on IT or product teams."
"There are a lot of limitations with the out-of-the-box tool."
"I would like them to reinclude PowerPlay. One thing that I am missing in the current Cognos is what was formally named PowerPlay. They have basically removed PowerPlay from it, which is something that I fail to understand because it was the most wonderful tool for business intelligence that I've ever used. As far as I know, they don't provide this functionality anymore, so this is one thing that I dislike about Cognos."
"In terms of what could be improved, I would say, monitoring, monitoring, monitoring. Some improvements in monitoring would be helpful. I'd like to see more monitoring of specific reports and fields. The way the auditing is now is very limited, so I'd like to see more of that - of the monitoring."
"I would like to see is more easy building, movement in the reports, and dashboard functionality within reporting. Overall more simple elements within reports. If the elements are simple then you don't have to render a full page, but you can move separate parts in the page."
"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."
"It would be nice to offer free online training on the tool for end-users."
"The technical support team’s response time is slow and needs to be improved."
"It could have more options for themes."
"SAP BusinessObjects has some semantic layer designs that give the flexibility to do ad hoc reporting or dashboard designing. If that can be brought into Tableau, it would be great. We have the data in the database, but we should also be able to bring something between the database and the dashboard and do some semantic layer modeling for ad hoc reporting requirements."
"It needs more ETL capabilities, to be able to address the end-to-end BI need."
"Most of the problems in Tableau Online that I have noticed have to do with performance or weird, inexplicable bugs that I can't pin down. For example, you might try unloading some data, and you'll be waiting for a long time without anything happening."
"The tool's OpenAI integration was announced last year. However, it is late. Tableau is a good solution for end customers. However, there are some concerns regarding the stability and performance of its server architecture, including SaaS services. The server side appears unstable, and performance issues are noticeable, often accompanied by unclear error messages."
"I would like Tableau to handle geospatial data better in terms of multiple layers and shapefiles."
"I would like them to include the Italian language, as I can see there are other foreign language in the product."
"Implementation requires a technical background."
"Areas for improvement would be visualization and augmented analytics. In the next release, I would like to see automated insights from the data added to the dashboard."
