When you don't have the time to be intricate with your calculations you will often find yourself, at least, contemplating estimation. If you need to make a quick (on the spot) judgment often we can only resort to estimation to get the job done. While many people feel that estimation is a simple guess, it truly is a skill that can make or break you in many businesses. When working with estimation we are not looking for the exact answer. We just want a ball park figure that can help us make an informed decision. We do this all the time when we are packing and moving. Will that fit in that box? Will that fit on that truck?
When we go to the grocery store, we are constantly estimating to find the best price. Is it better to buy 3 for $4.99 or $1.25 each? Can you see where estimation skills can save and really make you money?
