Review summaries and opinions

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

ROI

Sentiment score
6.7
IBM Cognos offers mixed returns; some save significantly, others find it costly, but generally enhances insights and processes.
Sentiment score
7.1
Tableau improves decision-making and efficiency, offering quick adoption and high ROI, especially when replacing outdated systems.
This saves a significant amount of time, particularly for reports that would have needed around fifty people.
The ROI of using Tableau extends to its seamless integration across various platforms, as it's from Salesforce and thus not limited to any specific cloud provider.
 

Customer Service

Sentiment score
6.5
IBM Cognos support is responsive and expert but criticized for high costs, slow resolutions, and complexity in customer service.
Sentiment score
7.1
Tableau's customer and sales support is praised for responsiveness, with technical assistance valued but needing improvement in some areas.
I rate technical support from IBM as eight out of ten, indicating a high quality of service.
They provide quick email and phone responses and have Thai-speaking personnel.
I find Tableau's technical support to be good with elite support, but it struggles with usual, general support.
Rating it nine out of ten.
 

Scalability Issues

Sentiment score
7.5
IBM Cognos offers scalable solutions, supporting large deployments with proper server architecture, powerful hardware, and seamless software integration.
Sentiment score
6.7
Tableau's scalability is influenced by server setup, workbook design, and is improved with new releases, despite pricing concerns.
It can be scaled out to other teams, but requires building cubes and implementing policies.
Tableau is easy to scale.
Tableau is easy to use across various dimensions, whether on-premises or on the cloud.
The solution is fully scalable and performs well even with large datasets, provided there is proper supporting hardware.
 

Stability Issues

Sentiment score
7.2
IBM Cognos is praised for stability and performance, surpassing competitors, with minor issues often due to server configuration.
Sentiment score
7.3
Tableau is generally stable, with improvements in newer versions, but issues may occur with heavy loads or poor infrastructure.
I rate the stability of this solution as nine out of ten, indicating it is highly stable.
The application hangs after continuous use due to the buildup of cache.
I rate the stability a five or six because Tableau updates very often with new versions or patches.
 

Room For Improvement

IBM Cognos needs UI upgrades, better data visualization, improved performance, and advanced self-service features to compete with rivals.
Tableau needs enhanced data integration, advanced analytics, cost-effective licensing, and improved enterprise features for user experience and performance.
There is room for improvement in self-service analytics and predictiveness.
It sometimes requires extensive investigation to determine why the data does not appear correctly.
Tableau currently lacks some modern features like AI generative approaches, video type analytics, voice command, and some predictive analytics features.
Pricing is also a concern for me as it is expensive compared to TIBCO Spotfire Enterprise licensing and Microsoft Power Platform.
 

Setup Cost

IBM Cognos is costlier but offers extensive features, complex licensing, and competitive SaaS options for SMEs, emphasizing negotiation.
Enterprise buyers should consider Tableau's varied licensing, higher costs, and flexible options compared to alternatives like Power BI.
I rate pricing as a four, meaning it is more expensive compared to other solutions.
Power BI as a much cheaper alternative.
A license for 150 users costs around $17,000 USD per year.
I think Tableau is expensive compared to TIBCO Spotfire Enterprise licensing and Microsoft's Azure and Power Platform.
 

Valuable Features

IBM Cognos offers powerful analytics, flexible reporting, strong visualization, and robust security with scalability and ease of use.
Tableau offers a user-friendly interface, dynamic visualizations, and integrates diverse data sources for effective, real-time data analysis.
IBM Cognos is a robust governed platform with significant security features and provides excellent graphics and reporting.
Building hyper extracts and visualization capabilities make Tableau a robust tool for data analysis.
The real-time data processing eliminates the lack of timely reports or dashboards, allowing for hour-by-hour updates instead of monthly or weekly ones.
Tableau serves as a stable dashboarding tool for higher management, aiding in quick decision-making.

Featured Reviews

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.
Nattawat Choosuwan - PeerSpot reviewer
Real-time data connection enhances workflow and decision-making process
An area for improvement in Tableau is the Explorer license type. It is not as useful, and the product owner should enhance its benefits or clarify its role. Additionally, the frequent updates with many versions available for download can be confusing and could affect stability. They should avoid providing access to older versions on their website.
