When I started with GOGO, Tableau was one of the BI tools used across the company, where we have distributed usernames to multiple people for their development or usage. I played a key role to enable Tableau as an Enterprise tool with AD Authentication (OKTA Integration,) which helped hugely increase traffic to the Tableau Server.
Most of the departments like Finance, Supply Chain, Airline customers, etc., use Tableau. The only department that I see we are lagging in is HR. HR is looking forward to automating the dashboards, but due to connectivity issues with Workday (as Tableau doesn't have a Workday connector,) we are unable to automate the dashboards.
The Supply Chain department is very much impressed with the tool, as they have had a lot of work reduced at their end. Also, they have better tracking of the vendor details & gap analysis of the stock purchase, which saves a good amount of money for the company by avoiding penalties for late delivery.
