Creating Reports on the Production System

Hi,

We are authoring our power users in production. We would like to know what are the Pros/Cons permitting super users to create queries on the Production system. Moreover i would also like to mention that:

No of Power Users = 25

The data in QA or dev is very less, as a results users find difficulty to validate their queries unless transported to the Production.

Would you be kind enough to provide us valuable suggestion.

Kind Regards

Noor
