Our product has been implemented across several sites. We use SQL Server.

What has come to our notice is that too much time is being spent fixing the sameproblems over and over again. This is due to the fact that some one at a particular site notices a problem, fixes it up and doesn't bother to inform others about it. When the same problem crops up at another site, the person over there fixes it up as well.

The problem, we now have two different version of codes since PERSON A failed to inform the central team about the problem encountered since he or she thought it was not 'worth informing'. We have now started a code consolidation exercise which is going on forever.

This is another worst practice. Not bothering to inform 'trivial changes'.

Cheers!
