AMOL JAJU - PeerSpot reviewer
Offers ad hoc analysis reports and good for operational dashboarding
There used to be many valuable features, but in the last three or four years, whatever IBM is doing with enhancements, it has taken a lot of time to build and develop. But the best usage of Cognos is the ad hoc analysis reports. I really like that. Our customers also like that. But now the usage of Cognos and OBIE is reduced by various business users because people and business users are now more focused on analytics, slice and dice, and the dashboard, and the widgets.
ROMIL SHAH - PeerSpot reviewer
Provides fast data access with in-memory extracts, makes it easy to create visualizations, and saves time
When it comes to visualizations, Tableau has a limitation as compared to Power BI. It has a limited set of visualizations. Power BI has the entire marketplace, so you can connect and import many visualizations and use them, whereas Tableau has only 10 or 15 visualizations. There should be more visualizations, and there should also be data integration with more cloud providers. Tableau has recently launched a paid version for the documentation. So, documentation has become a little bit challenging when it comes to Tableau development because we do not have any tool to export the data out of it. It is a license-based feature that you need to purchase to prepare documentation. So, on the documentation front, for preparing clear documentation for any dashboard, it would help if we get an embedded option, rather than buying a license for each user for the documentation. To document anything, if I have to connect to each workbook and see what has been written as a formula and then document in the Word document, it is pretty time-consuming. We have the Microsoft stack, and we are currently evaluating Power BI because Tableau has a limitation of 50 columns for a drill-down report. If we want more than 50 columns, we have found a hack, but there is no ready-made option for doing it. So, we have to use another tool in case we need a drilled report with more than 50 columns. There are many instances where users need 80 or 90 columns for their analysis, and switching between two technologies becomes a challenge. It is not a cost-effective approach for us. Their support should be improved. We are not happy with their support. Whenever we raised queries, we were pointed to a few blogs, and we didn't get a proper solution from them. Their licensing should also be improved. They want us to purchase a Tableau Creator license for business users, whereas Power BI Desktop is free for business users. They should come up with a basic license with one or two connectors that our business users can use for preparing their visualizations. Tableau also charges us per user for users who want the data only through email.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"For planning, forecasting, in-boxing, modeling in general and for predicting numbers and doing work analysis, they are excellent."
"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."
"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'."
"The three IBM Cognos features I find the most valuable are Dynamic Cubes, PowerPlay, and Watson."
"We are able to generate quality reports easily which allows us to decrease response time."
"One of the strong suits of Cognos is its robust corporate reporting capability."
"The most valuable features are Report Development (Functionality) and Information Distribution (Flexibility)."
"IBM Cognos offers tools so that you can design and develop your own test queries and reporting solutions."
"From my perspective, it enables clients to better understand our data and make better decisions based on that information."
"Easy to create graphs and visualizations."
"Very user friendly."
"The platform's most important feature is predictive analysis."
"Tableau Prep tool for data preparation is a most valuable tool."
"Tableau is easy to use compared to some other solutions, such as Excel."
"Tableau has many different connectors for different databases. It's very easy to connect to MySQL, SQL Server, Amazon EMR, Presto, Redshift, BigQuery, and so on."
"Tableau's most valuable feature is its ability to connect with various data sources and display real-time data on three different dashboards."
 

Cons

"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."
"Tableau and Power BI are faster than Cognos."
"The solution seems to slow down the servers."
"One key area for improvement is the need to improve the self-service nature and functionality of the product in terms of visual analytics."
"The solution's support could be better."
"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 performance is a bottleneck and something that can be improved."
"It is a costly product; it is comparatively expensive."
"More integration with Python or something related to machine learning would be a good improvement."
"From the developer perspective, the data connection handling the target data set is what most needs to be improved."
"An advanced type of visualization is a bit tricky to create. It has something called a Calculated field, and that sometimes gets a bit difficult to use when you want to create an advanced type of visualization."
"When I've done presentations in the past, I've had issues with uploading the cartography."
"It's already using 32 gigabytes of memory, but the performance is not so good. It's very heavy."
"There could be improvements on the mobile application, it is lacking features."
"We would like a report model, because currently there is no schema that we can create in the tool."
"The customization requires a lot of effort and should be simplified. The performance could be better."
 

Pricing and Cost Advice

"I don't know the exact cost, but I believe Cognos is quite expensive, especially when it comes to the support consultants and the procedures that need to be applied."
"IBM Cognos is priced reasonable. However, it is more expensive than Power BI and Tableau."
"I rate the product price as four or five on a scale from one to ten, where one is a low price, and ten is a high price."
"IBM Cognos price is on the higher side of the spectrum. However, with the features that it brings, such as correlation analysis, it's worth the money. They should look at the pricing more clearly because it's a little on the higher side."
"The pricing and licensing policies are comparatively cheaper than other products in the market ."
"The pricing of this product is meant for medium to large-scale enterprises."
"There is a standard license required to use this solution. There are some additional tools but I am not sure if they are an extra cost."
"It is my understanding that the cost is very low. It's not very expensive."
"Licensing fees are paid on a yearly basis."
"Tableau can be costly (but this can be indefinable, such as user experience vs. cheaper etc.)"
"Its price is higher than Power BI and QlikView. Tableau costs around $70 per user per month, whereas Power BI is around $8 to $9. QlikView is around $30. Tableau has various prices for various models such as Creator, Designer."
"Tableau is an expensive solution, though it comes with its advantages."
"The cost is high."
"The product's price is relatively inexpensive and manageable for enterprise-level companies."
"There is a license for the use of this solution and it is on a per-user basis. The server is free but the users you have to pay for."
"For our organization, the cost hasn't been an issue."
