history: I work in tech support and we often have complicated issues.  There was one recently where they needed to move data but I did some research before it happened and knew exactly what I needed to do to get the data over.
current: I work in tech support.  One issue I was given the details before and got to do research before I worked with the customer.  It was great knowing what to do before it happened.
next: You must have been relieved you were able to help. Did all go as plan?
