Prior to Tableau, employees in data heavy departments such as trading and generation were completely reliant on the IT department for all their analysis and reporting needs. Not only was this both expensive and time consuming, but it created a damaging disconnect between key data insights and those that needed them the most.
“The IT department was a big bottleneck to productivity,” said Rene Greiner, VP of data integration at Uniper. “Reports took a long time to come back and when they eventually did, many of them were invariably ‘not quite right’, causing even more delays and frustration as teams had to go back and ask for them to be done again.”
Rene knew that adopting a self-service approach to analytics had the potential to eliminate these issues but doing so first required a major overhaul to the way data was handled within the company. So, in 2015 Rene and his team began a major project to replace the existing data warehouse with a new data lake. Then, following an extensive competitive review process, Tableau was chosen as the sole visualization and analytics solution to integrate with the data lake, forming the new Atonyx data platform, which was opened to employees in January 2018.
“We spent a lot of time looking at all the leading solutions on the market from vendors such as SAP, IBM and Oracle,” said Rene. “In the end, Tableau’s powerful visualization capabilities, seamless integration and ease of use made it the top choice in nearly every category.”
With Tableau in place, over 600 employees can now self-serve their data analytics needs, eliminating reliance on the IT team and keeping data firmly in the hands of those that need it.
“Using Tableau, key teams can pull data, conduct high quality analytics and create visual dashboards in the timeframe that suits them, not somebody else,” says Rene. “As a result, business intelligence and operational performance have improved across the board.”
