servicenow

Did it ever happen to you that you developed something on dev instance but tested on another OR accedently you created something directly on prod/test just because you didn't notice that the record you are modifying is not of dev. If yes, then don't blame yourself, as this is common mistakes that almost all developers have done at some point of time, who works on multi-instance tools like servicenow where you have one instance for development, other for testing and separate one for production. So, is it possible that while making change to any record I can have something that remind me of the instance other than looking at the URL?  Answer is yes. One solution that I used to have in my intitial days, it used to help but was not very effective. I used to change the theme of all the instances so let's say OOB theme for production, blue for development and green theme for test instance. But this is effective only when you open records in the frame of the servicenow main page.
