We need a precise vocabulary for signals intelligence.

How about this metaphor? A women shopping for clothes will go to a store with a broad selection, any item of which she may purchase. She will pass quickly by most racks of clothing; that might be called "acquisition" and "initial screening". She will, however, go to some racks and examine the contents piece by piece; that might be called secondary screening. A few things will make it to the changing room to be inspected on in a mirror; tertiary screening. Finally she may purchase a piece or two and take them home; storage. Reviewing the purchase with friends and family may result in rejection of some purchases (and their return to the store) and addition of others to the wardrobe; analysis, acceptance and utilization.
