Tableau

The ability to use multiple data sources and live data from server to build a dashboard is amazing. The final result is organized, professional and implementing changes on different sheets is simple and easy.

Tableau is a powerful tool for data analysis, it unifies data from different sources for a better view of the information and thus being able to make decisions that best suit the projects, it works very well with other platforms such as Salesforce.

We were on 30 days trial. The trial was about to expire but things didn't work correctly. Tableaus aggressive onboarding team made me sign for a one-year contract anyway. They promised to support us until everything works. But that did not happen. So I talked to them. Someone seemed to understand and said, he'd cancel the invoice and give us another trial and hopes, thins will work. After a few months, it worked indeed. So we purchased again. But: we never got a license even we already paid. Statement: the old invoice needs to be paid. So although we have a written confirmation, that the invoice is cancelled, tableau didn't cancel and now we have no money and no license. Very sad company. The product might be great but the philosophy horrible.

I have a positive overall experience with Tableau.

The tool is must and Tableau prep is more effective as it reduce the data cleaning work drastically. Even you can use processed data to Python or some other analytics rather than Tableau Dashboard itself.
