I would think this would be an easy argument to make :-). The way I 
would look at it is to figure out how would separate types of incidents 
affect productivity in an organization. For example virus outbreak takes 
down whole network resulting in 100 employees losing 8 hours of 
productivity. If IDS was present there would be only 2 hours lost 
productivity. So with IDS there is 6 hours less lost productivity due to 
early alerting, containment etc. In money terms than you can come with a 
dollar figure e.g. 6 hours times 100 employees = $XXXX. You may be able 
to find what the average number of security incidents for organization 
of your size on the net.
