It is amazing the time I spend on tasks only to find that the project plan was lacking and when I got to step 10 (there were only 2 steps in the beginning), step 2 was wrong. As a SQL DBA, Project Manager, Application Support… you must ask questions.
One example was a emergency request I received to support a project. They had restored databases and login would not work. I ran sp_fix_user_login and they were good to go. Case closed, I have a million other things to do anyway.
I received a call from the production team a couple months later saying I had supported a roll to QA and needed all the documnetation. I looked back and wait I just helped them with a issue. I never even saw that it was a qa roll and not marked “issue”
I had to restore and do the full roll over again deal with all the issues because they wanted dbo on the whole databases. Get blamed for delaying the project..
