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.
"I have worked on the features like dashboards and stories, and I do like them a lot."
"Dashboarding, reporting, and ad hoc reporting are the valuable features of IBM Cognos."
"This solution allows you to input a wide range of file formats."
"The most valuable features of IBM Cognos are governance and enterprise reporting."
"A positive feature is Report Studio, where we create beautiful, complex reports."
"A drag-and-drop interface for selecting creating ad hoc reports makes this product very easy to use."
"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 solution's initial setup process is easy."
"Tableau is good for routine dashboards, and it has integration with Slack, through which it can send you daily updates."
"It's very easy to use and users don't need any IT support to access it as the information is right there."
"The solution is being delivered to our customer, who appreciates the insights generated from the reports. It is easy for them to drill into the details and use interactive charts."
"We found Tableau has the quickest learning time out of the few other BI reporting tools that we have used."
"The most important feature is the tool is very easy to use. This makes it simple to introduce it to CxOs. After a rapid demo, they are usual impressed by the results shown, because it has such a rare simplicity."
"One of the most valuable features of Tableau is that it's a visual analytics solution, not just a dashboarding solution. Compared to Power BI, which is a dashboarding solution, there are no limitations with Tableau. For example, when you add a chart or a map to Power BI, it has a 3,000-point limitation. When you try to track your whole vehicle on the map, you only see the first 3,000 rows on the map, and Power BI doesn't tell you which part of the data is shown on the map. But Tableau doesn't have any limitations, which means that you can see five million data points on a map. It starts the project by creating the visuals that directly converts to SQLs. In that way, all the components have no limitations. When we compared Tableau to Power BI, we also found Tableau to be more fancy. Fancy means you can create more visual graphics and more visual dashboards. With Power BI, this isn't so—it's just some tables and some simple charts together. Tableau is more for business users who want to analyze data. Tableau can directly connect the analytics systems, like R or Titan, and get the results in screen, so it's a good solution for analytics scientists. It has some predefined capabilities to understand the data."
"Our customers love the visual capabilities on top of it and the ability to explain and get the required data. There is no other product like Tableau in the business intelligence and analytics space."
"The platform's most important feature is predictive analysis."
"Chart quality: many other competitors have charts and graphics that look much better and that provide dynamic effects. Cognos doesn't."
"It would be better if it is was easier to implement without extensive training for it."
"One key area for improvement is the need to improve the self-service nature and functionality of the product in terms of visual analytics."
"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 think the GIS pieces maybe not as good as we would like."
"Extending dynamic cubes aggregate awareness with calculated measures."
"They should provide improved visual reporting."
"One thing that we really want is the ability to have data portrayed on an image. Cognos is not able to do it at the moment, and that's becoming a requirement from the business side: having an image and then plotting your dataset on top of the image as a map."
"I think Tableau could be improved with cheaper or more flexible licensing, though this is a generic improvement and applies for any product. It would be better if they had more flexible payment and licensing plans so that they could suit small- and mid-sized organizations."
"I would like Tableau to handle geospatial data better in terms of multiple layers and shapefiles."
"I would like Tableau Prep to be integrated with Tableau Desktop. I would also like more customizations for tables."
"Tableau is an end-to-end analytics platform, and it is doing a pretty good job in terms of connecting to the data and analyzing it. It can, however, do better in terms of data management and the ETL features, which are not on the advanced analytics or machine learning side. Tableau Prep is where users would want to see more advancements. They can improve Tableau Prep, which is an analytic platform tool for data cleansing. People who work with data spend most of their time curating the data. Cleaning up the data and getting it ready for analysis is what takes the most time. If Tableau can invest more time in improving the Tableau Prep platform, it would be great. Previously, Tableau didn't have the functionality for writing to a database. So, you couldn't really alter the database tables and write to your database, but they fixed that in one of the very recent releases. However, it isn't really advanced and should be improved."
"The only issue with the solution is with its prices at a regional level."
"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."
"When I've done presentations in the past, I've had issues with uploading the cartography."
"The charts need to be improved. The drawings and the visualization need to be more accurate."
