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 most valuable features of IBM Cognos are governance and enterprise reporting."
"We are able to generate quality reports easily which allows us to decrease response time."
"Integration with Office can enable the 'download' mode of storytelling."
"I have worked on the features like dashboards and stories, and I do like them a lot."
"Security administration tools are powerful and flexible."
"The most valuable feature is developing reports from different data sources, making it a reliable data source."
"The basic platform comes with several meta-modelling tools."
"Report Studio: This is the most powerful and sophisticated tool for professional reporting."
"Easy for beginners to use"
"It's very easy to set everything up."
"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."
"It's very user-friendly. It's not like Power BI, Tableau is very user-friendly. Anybody can use Tableau. It's very easy to adopt things. I can visualize the stats."
"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."
"This service is the combination of very pleasant, interactive graphical visualizations along with the application of advanced statistical models (in some cases)."
"You can create attractive dashboards that inform users using Tableau."
"It's very easy to use and users don't need any IT support to access it as the information is right there."
"They should provide improved visual reporting."
"Tableau and Power BI are faster than Cognos."
"The AI-based features could be further enhanced by the solution."
"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."
"I would like to see the introduction of mapbooks for supporting some geographical information."
"Extending dynamic cubes aggregate awareness with calculated measures."
"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."
"We would like to see development of the product's UI function, to make it more of a UI tool that can be configured as required."
"I would like to have the product be more flexible in terms of creating online shared dashboards."
"In the next release, I would like to be able to have the option to see more raw data that I'm converting on the dashboard."
"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."
"Provide additional enhancements in any business process: Operations, Marketing and Sales, Finance, Human Resources, Logistics, etc."
"Tableau is a company that does not respect partners."
"Tableau has so many functions, so sometimes it's hard to find the right solution quickly. I have to search multiple menu bars to find the right command."
"The process of embedding the dashboards on external portals and websites could be improved."
"I have used Power BI as well as Tableau. There are a couple of interesting features that I like in Power BI, but they are not present in Tableau. For example, in Power BI, if I am looking at country-wise population, I can type and ask for the country that has the maximum population, and it will automatically give an answer and address that query. This kind of feature is not there in Tableau. Similarly, in Power BI, for integrating with the latest ML algorithms, we have decision trees and primarily multiple machine learning algorithms. The decision tree essentially visualizes the patterns in the data. We don't have such a feature in Tableau. If Tableau can integrate with the machine learning algorithms and help us to do visualizations, it would be a wonderful combination. Most of the people are going for Tableau primarily for visualization purposes. However, in the data science industry, users want to do model building as well as tell a story. As of now, Tableau is fulfilling the requirements for visualization purposes. If they can bring it up to a level where I can use it for machine learning purposes as well as for visualization, it would be very helpful. Many people who want to do data science don't want to write a code. Tableau is anyway a drag and drop tool, and if they can provide those options as well, it will be a powerful combination."
