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
7.0
Sisense streamlines report processes, saves time, and benefits decision-making, though effectiveness varies by user experience and region.
Sentiment score
6.9
Tableau Enterprise delivers rapid returns through efficiency, cost reduction, quick insights, and enhanced decision-making within six to twelve months.
Due to the data presented to stakeholders, they are able to make informed decisions that impact the day-to-day operations of the client, giving them more insights into what's happening within their organization.
I have seen a return on investment in that we can manage the Sisense environment with a very small number of users.
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.
Tableau is saving me time, money, and resources, which I would rate as ten.

Sentiment score

Sentiment score

Sisense is scalable and user-friendly, but querying time increases with more data; security requires careful management.
Sentiment score
6.7
Tableau Enterprise's scalability varies, effective with design and configuration, but big data performance concerns and costs remain.
It can be scaled out to other teams, but requires building cubes and implementing policies.
It is scalable to a very large extent and we can integrate any third-party tools.
Sisense works really well for simple to medium use cases and scales well.
Tableau is easy to use across various dimensions, whether on-premises or on the cloud.

Stability Issues

Tableau Enterprise is generally stable and reliable, with occasional issues mainly related to large datasets or server configurations.
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.
Sisense should improve large dataset support, add connectors, enhance interfaces, and expand customization for better performance and user experience.
Tableau Enterprise users seek better data integration, improved performance, cost-effective pricing, and enhanced analytics and collaboration features.
There is room for improvement in self-service analytics and predictiveness.
I would like to see an improvement in the live data connection, specifically making the process faster.
It could provide more connectors to integrate with emerging different data sources to exponentially increase the amount of data it can handle.
I give Sisense a nine because the integration with some third-party tools is good.
We cannot send the entire Excel file reports via email within Tableau.
The product owner should enhance its benefits or clarify its role.
It sometimes requires extensive investigation to determine why the data does not appear correctly.
 

Setup Cost

IBM Cognos is costlier but offers extensive features, complex licensing, and competitive SaaS options for SMEs, emphasizing negotiation.
Sisense offers competitive enterprise pricing from $35,000, suitable for mid-stage startups and large enterprises, with customizable options.
Tableau's pricing is high yet competitive, with increased costs for added features, posing challenges for small organizations.
I rate pricing as a four, meaning it is more expensive compared to other solutions.
There was no significant difference in pricing between Sisense and ThoughtSpot.
My experience with pricing, setup cost, and licensing shows that pricing is a little bit higher when compared to other applications, but that justifies the use case.
Power BI as a much cheaper alternative.
A license for 150 users costs around $17,000 USD per year.
Looker is known to be quite expensive.

Featured Reviews

Robust platform delivers excellent reports and insights while needing improvement in self-service capabilities
Our clients utilize IBM Cognos mainly for static reporting, board packs, business reporting, and insights IBM Cognos is a robust governed platform with significant security features and provides excellent graphics and reporting. One of our customers can get a full company update on a Monday…
Vishal Halbe - PeerSpot reviewer
Has improved project turnaround time with customizable dashboards and faster data delivery to stakeholders
Sisense has some limitations, especially in rendering tables or graphs. For example, if you want to perform custom sorting or searching based on multiple columns, that becomes quite tricky. Providing more control over how the data is sorted or filtered would be quite useful. Additionally, it could provide more connectors to integrate with emerging different data sources to exponentially increase the amount of data it can handle. Sisense should provide more support for CI/CD, as we found the CI/CD approach quite limited, which is something that can be worked on. Some data scientists suggested more features can be offered by providing different models for data analytics. Sisense can improve by adding more features for handling complex schemas and making the pricing straightforward. The dashboarding features are good enough, but additional features could make it even more attractive. Also, CI/CD support or source control support would be really helpful.
Uzair Faruqi - PeerSpot reviewer
Ease of developing dashboards and receiving strong technical support have enabled efficient data visualization
Introducing custom features, such as NLP-based reports, is not very good in Tableau. My MD has been asking us for a way to write in natural language to request reports that the system should generate, but that isn't very effective with Tableau. As a developer, I can develop an on-demand report in Python quite easily, but exposing a REST API on the Tableau platform is not a very easy task. AI enablement is an area for improvement for Tableau, and that is something they might have to work upon. I have heard that ThoughtSpot is quite better in this regard, but the cost of ThoughtSpot is much higher. ThoughtSpot has lots of natural language-based report generation features that Tableau lacks.
