How quickly do you make decisions? Give me an example.

"I consider myself to be very decisive. I prefer to reach a conclusion and make a decision as quickly as possible. I do this by collecting the information I need, analyzing the pros and cons, selecting a course of action, and moving forward. I also consider alternatives and determine when I might switch courses if my decision turns out to be incorrect. An example of this in my last position was when I was asked to recommend a hardware upgrade for our group. I quickly analyzed our current requirements, projected how these would grow during the next 18 months, and determined what off-the-shelf hardware would meet our needs. I looked at the total cost of ownership for three systems and chose the one that would do the job at the lowest cost. This turned out to be the correct decision based on the performance of the system and the fact that it met our needs for the subsequent 24 months."
