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.
"A positive feature is Report Studio, where we create beautiful, complex reports."
"IBM Cognos improves the effectiveness of the sales team."
"The product is a very good reporting tool and is very flexible. It allows for the users to get a scheduled report."
"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."
"We use IBM Cognos for enterprise analytics and reporting."
"The dashboarding offered by this solution is very valuable to us."
"The initial setup is quite straightforward."
"Integration with Office can enable the 'download' mode of storytelling."
"The data blending capabilities is a huge factor for our team."
"The most valuable feature is the aggregation function."
"The platform's most important feature is predictive analysis."
"It provides business users with a tool, so they are not dependent on IT."
"It is easy to use, and it can handle a large amount of data."
"Tableau is easy to use compared to some other solutions, such as Excel."
"Tableau has many good features. It is user-friendly, has a simple-to-use interface, and has a customizable dashboard."
"Tableau's visualization features let you present information insights quickly and practically. So it's something which I prefer with Tableau. In terms of reporting, I have to point out the sheer quality and function of the Tableau server, but the first impression is that it's a great visualization tool."
"It would be better if it is was easier to implement without extensive training for it."
"They were lacking in the initial phases of development in the area of big data, and they still need to improve that aspect of the product."
"The high cost of a license makes it hard to scale up on a budget."
"I think the GIS pieces maybe not as good as we would like."
"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."
"Chart quality: many other competitors have charts and graphics that look much better and that provide dynamic effects. Cognos doesn't."
"IBM Cognos's error messages seem to be a bit ambiguous. An error will be encountered and a message will be sent out very ambiguous and after investigating the error message it could be any number of issues. There was never a direct answer to the question or a direct answer to the error messages. Sometimes it would be a generic error message for 21 different solutions. It wasn't very specific, which required a lot of digging around and trial and error trying to fix the problem. The messaging in their error messaging is something needing improvement."
"Need improvement towards Visualization."
"If you wanted to create something without making it an extra column in the data set, you can't just rename it to a more user-friendly short name."
"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."
"Lacks machine learning algorithms that you can implement using R, SPSS Modeler, and Python."
"There could be improvements on the mobile application, it is lacking features."
"The price could be better."
"The pricing is a bit expensive."
"Some of our clients are looking for better UI when using Tableau as they often work with this solution directly."
"If I have to develop any, for example, pie charts, I can develop them just fine. However, if I have to develop a donut chart, that I cannot do it in a simple way. There are tricks that I need to use if I have to design a donut chart. It should be more flexible and provide more visualization options."
