As a consumer, when you want to purchase an item, whether it is a new car or a flat screen television, you will most likely do some research on the prices of your local stores or from vendors on the internet. When you have narrowed your search you then look at other criteria that may be important to you, like warranty or availability. Lastly you will look at other less tangible criteria such as your previous experiences with the vendor and how their customer service was.

The purchasing department would evaluate the vendors based on a number of criteria they had decided upon which may include objective criteria such as price and warranty and subjective data which would include past experience with the vendor. Based on the weighting given to these criteria the purchasing department would be able to fairly evaluate each vendor.

Many companies use a vendor evaluation tool that allows transaction data to be analyzed to give a comparison between vendors. The vendor evaluation uses criteria that have been determined by the purchasing department to compare vendors such as price, delivery reliability, delivery date adherence and quality of the
