I guess the first issue we would need to solve for this discussion to be meaningful is whether or not indexes or indices is the appropriate term when referring to multiples because if you are going to use these tools for procuring products, there are many to consider.
From a simplistic perspective an index is a system used to make finding information easier. There are any numbers of indexes or indices available to help procurement knowledge workers insure they are sourcing products at the best possible pricing. The key word here is price as what we will be discussing are specifically price indices.
According to Wikipedia a price index (plural: ?price indices? or ?price indexes?) is a normalized average (typically a weighted average) of prices for a given class of goods or services in a given region, during a given interval of time. It is a statistic designed to help to compare how these prices, taken as a whole, differ between time periods or geographical locations.
Price indices have several potential uses. For particularly broad indices, the index can be said to measure the economy’s price level or a cost of living. More narrow price indices can help producers with business plans and pricing. Sometimes, they can be useful in helping to guide investment.
Normally an index reflects the current and historical price of a variety of commodities ranging from metals to grain. A common index used in sourcing petroleum products is OPIS or the Oil Price Information Service which you can learn more about by visiting www.opisnet.com.? However in order to drive the best possible fuel pricing there are other dependencies such as whether you are doing spot buys or bulk purchases and these strategies will determine what specific index you would want to review as well as it?s relation to other product information sources such as Platts or the Gulf Coast spot assessments.? This will put you in a better position to determine how to bid the product and also earn a discount relative to the lowest common denominator.
All other commodities have similar sourcing issues dependant on what the highest cost item is in their product makeup. An example here might be the cost of grain in the feeding of cattle or poultry.
Ask you solution provider to explain these tools to you and to recommend how you might use them toward the best outcome.
We look forward to and appreciate your comments
