It's here that the "OPERA" method of purchasing comes into its own. It enables us to establish a rigorous methodology for the whole lifetime of the project in order to make sure nothing is forgotten and no time is lost.

The aims are:

		To optimize the quality and cost of purchasing
		To encourage creativity on the part of suppliers by means of clearly expressed expectations
		To encourage a thorough functional analysis of the need
		To create a competitive context
		To facilitate the evaluation of responses
		To encourage communication with suppliers
		To create a group experience
