Years ago we were just APs (analyst-programmers for the youngsters who've never heard the term). We didn't have a methodology, we just talked to the users at different levels in the business to find out what they wanted & did it.
As the team varied in size from 1 to 4 we didn't have separate sysadmins or DBAs, we just did the lot. If you have to administer what you write what you write tends to avoid admin problems.
I can't remember what shape I was then but whatever it wasn't the shape I am now - things have filled out & sagged a bit.
If this is going to be a regular Monday slot I must remember to avoid it.
