I have friends that are as passionate about scrum as I am. To my utter delight, I hear stories about how they apply Scrum to the most unlikely places. One friend applies it in her home for their weekend chores. Another planned a wedding using it. I know she trusts the process because the wedding was her own!
I have been pleasantly surprised when we applied it to our hardware development. I guess I shouldn't be surprised. If you can break up your work into small groups, you can Scrum it.
So let me pose this question, where have you applied Scrum? Have you applied it to anything besides engineering?
