tima | still not enough

Interesting - we have just one production database instance. For development we have another server with 3 database instances. For UAT - another with 2. And one more machine for QA. And that is still NOT ENOUGH! We do whole bunch of projects at the same time and as result everybody tries to screw up others! Spent a half day trying to test a fix and couldn't do it because there are a lot of changes everywhere in database structure.
Gave up and put it to production. Now kind of curious - will it work at all?!
