should permit the suggested price of the product to be increased due to the potential 
loss of revenue caused by delaying the entry of the product into the marketplace. In 
addition, those product features would incur additional development costs that must 
be recouped by product sales.
A trade-off situation involves a decision to be made with full comprehension of 
both the upside and downside of a particular choice. It implies forfeiting one fea-
ture or characteristic of a product or situation in return for gaining another feature 
or characteristic. Sensitivity and risk analysis are two notable techniques that sup-
port the trade-off analysis decisions. They evaluate possible alternatives in terms of 
the uncertainty in the analysis results and how these variations can be attributed to 
different assumptions.
