Build a joinable Data Mart library. Hand it off to stakeholders in Google Sheets. They pick columns, add filters, refresh on schedule — no SQL, no tickets, no you in the loop. But still you in control of results.

[temp] Every “can you add one more column?” request lands in your queue. Every ad-hoc export becomes a recurring obligation. Here’s what changes when the hand-off is the product.
[temp] The reporting backlog disappears because business users stop needing you to get data.
