Tableau

There are many features which lot of users would have liked:-
1. Connection to almost all database
2. Many types of Charts can be created including Sankey, Doughnut, Maps etc.
3. Its has the feature of data blending and data extraction
4. Dashboards can be viewed on multiple devices like tablet, mobile and laptops.
5. Its really fast while drilling down or filtering out from any dashboard.

Its a bit expensive tool as compared to other data visualization tools however its a value for money.

Tableau Desktop absolutely produces the cleanest and most intuitive reports of any software like it. The learning curve for basic functionality is short and the online resources for deeper dives are plentiful.

Reports distribution in Tableau Desktop is clunky and connecting to SharePoint or similar distribution tools are too difficult to setup without professional IT assistance.
Tableau Prep is still in early stages of development. Some Flows take much too long for what shouldn't be so challenging an operation.

Once you have your data ready in a way, tableau is able to connect, it's an easy to use tool.

There's supposed to be a web data connector between Filemaker and tableau. This is not working. Tableau sales representative do not care about it.

There is a reason that Tableau is synonymous with data visualization tools to many people and organizations. It’s a premium product that can do pretty much whatever you want it to.
Tableau’s features are limitless and with the proper resources to maintain and deploy it, you’ll rarely identify capabilities that it doesn’t have. It is truly a BI tool that enables your team to overcome any obstacle they face.
I specifically enjoyed some of the advanced visualization capabilities of Tableau that more “basic” tools don’t offer. The time series visualizations are easy to configure and are always a crowd favorite. The ability to deploy on-premise or in the cloud means that organizations can configure to their preference.
All in all, it is an incredibly powerful tool that leaves very few stones unturned.

The three biggest drawbacks to our organization continuing with Tableau were ease of use, cost scalability and functional scalability.
Tableau is not the tool for organizations that lack technical resources. It’s not as “plug and play” as other options on the market and requires significant training of architects to fully take advantage of all its capabilities.
Tableau also isn’t the ideal solution if price is an obstacle in your organization. Frankly, it ain’t cheap. Depending on your desired level of investment and the number of users you’ll need, it can run the tab up quickly.
Additionally, user management in Tableau itself isn’t an issue, but deployment presents its challenges. Other options on the market are much easier to introduce users to (here’s your login, go to this URL and boom, you’re good to go) whereas Tableau requires more configuration. This is dependent on which Tableau version you utilize, but there are efforts involved in scaling the platform.

Tableau seamlessly integrates with Salesforce and allows us to create beautiful reports and dashboards. Prior to this, we relied on Salesforce for all reporting and we found it pretty limiting or difficult to set-up. With Tableau, it's been very easy to see all of our reports in one place. I love that you can toggle on certain filters too to change the dashboards easily rather than having to edit the whole thing. We also have ours set to auto refresh daily, which saves us time. I always found that refreshing my reports or dashboards on Salesforce took some time, but with Tableau this process has been sped up.

I have yet to encounter any difficulties with this software. The process has been pretty smooth so far.
