When you physically install a product on one machine instead of the cloud, you have a better visibility, best icon quality, etc.. It's more of an issue with how we are adapting to the transition. We are still in the early moments of using this tool, and we need to go deeper to discover some improvements. 

The potential challenge, especially when considering a larger user base, is that the expenses can significantly add up. There are issues with integration and I encountered limits and warnings, especially with my pivot table size. It could potentially incorporate more functions in the future. Another point worth mentioning is related to graphing. When you have a large dataset, say a thousand customers, the bar chart might display only the first fifty or a hundred entries, making it less user-friendly for horizontal scrolling. Ideally, it would be more intuitive to scroll all the way to the right to view the last entries.

Stability and scalability an be improved for a full ten. 

Google Data Studio allows you to set up notifications for dashboard changes, so you don't have to adjust the fields each time manually there's a modification.

We connected it to BigQuery tables. However, sometimes, it was slow, mainly when the tables contained a large amount of data. We constantly refreshed it every 3 hours to provide real-time data.

There is a significant degree of sophistication required to compete with Tableau or Cognos.

The tool should come up with data modeling layer features that are present in other products like Power BI. 

Insisting on forums, blogs and community outreach in communications, and posting videos on an established calendar would be useful. Nowadays, people are visual or audio or even both in terms of acquiring new knowledge.

All panels, although they are easy to navigate once you have a clear understanding of the software, are not as easy to use as other data extraction UIs. Although you can start with basic Google tools education, you will need a solid explanation of data extraction.

If you do not have a complete BI tool, evaluate if your organization will have the need for one in the future. I'm sure Data Studios will grow and expand in the future, but it's not yet a complete replacement.
