Tableau Enterprise delivers rapid returns through efficiency, cost reduction, quick insights, and enhanced decision-making within six to twelve months.
In a world surrounded by data, tools that allow navigation of large data volumes ensure decisions are data-driven.
Power BI is easy to deploy within an hour, providing robust security against data leaks.
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.
 

Customer Service

IBM Cognos support is responsive and expert but criticized for high costs, slow resolutions, and complexity in customer service.
Sentiment score

Sentiment score
6.1
Tableau Enterprise support is praised for professionalism and multilingual assistance but needs improvement in response times and technical expertise.
I rate technical support from IBM as eight out of ten, indicating a high quality of service.
The significant drawback I notice is that Microsoft's size makes it hard to get specific change requests addressed unless they involve a bug.
We have a partnership with Microsoft, involving multiple weekly calls with dedicated personnel to ensure our satisfaction.
The support is good because there is also a community available.
They provide quick email and phone responses and have Thai-speaking personnel.
There should be consistent standards for all users.
The technical support for Tableau is quite good.
 

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
6.9
Microsoft Power BI offers scalability and integration, though optimizing large deployments may require expertise, especially with complex or large data.
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.
You expect only a small percentage of users concurrently, but beyond a thousand concurrent users, it becomes difficult to manage.
With increasing AI capabilities, architectural developments within Microsoft, and tools like Fabric, I expect Power BI to scale accordingly.
As more data is processed, performance issues may arise.
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.
Tableau is easy to scale.
 

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
7.4
Microsoft Power BI is stable and reliable, though large datasets may impact performance; frequent updates enhance its reputation.
Sentiment score
7.4
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.
In terms of stability, there's no data loss or leakage, and precautions are well-managed by Microsoft.
We typically do not have problems with end-user tools like Excel and Power BI.
It is very stable for small data, but with big data, there are performance challenges.
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.
Microsoft Power BI is criticized for high costs, complexity, handling large data, and lacking intuitive interfaces and AI integration.
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.
This makes Power BI difficult to manage as loading times can reach one or two minutes, which is problematic today.
Access was more logical in how it distinguished between data and its formatting.
Microsoft updates Power BI monthly based on user community feedback.
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.
Microsoft Power BI offers flexible pricing, from free to premium, making it a cost-effective business intelligence tool for enterprises.
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.
I found the setup cost to be expensive
Power BI isn't very cheap, however, it is economical compared to other solutions available.
The pricing for Microsoft Power BI is low, which is a good selling point.
Power BI as a much cheaper alternative.

Valuable Features

In today's data-driven environment, these tools are of substantial value, particularly for large enterprises with numerous processes that require extensive data analysis.
Within the organization, Microsoft Power BI is used to create dashboards and gain insights into data, enhancing data-driven decision-making.
To reduce the need for highly skilled personnel, we can engage someone who is just familiar and has a basic understanding of Microsoft Power BI, while AI can handle the major tasks through either agent AI or requirement analysis.
A significant feature for me is the real-time connection to data sources because it effectively manages large data sets.
Tableau serves as a stable dashboarding tool for higher management, aiding in quick decision-making.
Building hyper extracts and visualization capabilities make Tableau a robust tool for data analysis.

Shoury Priyanshu - PeerSpot reviewer
Facilitates seamless data aggregation with some outdated visual elements hindering user appeal
Real-time data integration is an area for improvement. Although I've worked on several solutions involving real-time integration, it's not very user-friendly and often lags, especially with over a million data rows. This makes Power BI difficult to manage as loading times can reach one or two minutes, which is problematic today. There are challenges with scalability, requiring multiple pages in dashboards to manage these issues. Visualization could be improved as it appears outdated. Users, especially newcomers, find it unappealing and not user-friendly.
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.
