This document aims at helping application developers to make sure that the technology (or packaged systems) they choose offer the best capabilities required by their application with respect to some price/performance ratios. For this purpose they should issue a ``Requirement profile'' to be sent to a large number of vendors. The requirements profile should be structured into two levels: a first level devoted to general information to determine the technologies to be short-listed, and a second level that should allow selection of an appropriate technology partner through an in-depth analysis of the adequacy relation between the application needs and the technology specifications. This process allows accurate comparison of the technologies while saving the time needed for such comparisons.
