 This wiki page describes different discussion points for the
 specification of the SPEC7.
 
+### Aim and Use cases
+
+#### NIKHEF - JRP
+
+\* Aim: the JRP want to disseminate UTC from metrology partners to
+European research institutes and industry partners with a target
+frequency instability of 1e-13 over 100 sec.
+
+\* Users will be first: research institutes, metrology institutes.
+Later: high performance users, telecom, ....
+
+* All users profit from an inherent high performance, relatively
+cheap, design without the bother of buying an expensive stable external
+oscillator that the metrology users need.
+
+\* Quantity: 100 in 5 years for metrology
+
+\* Priority
+
+1.  performance
+2.  cost
+
+#### CERN
+
+\* Aim: smooth replacement of existing SPEC for DIO, ADC100M, TDC, Fine
+Delay, WorldFIP master and other FMC mezzanines.
+
+\* Users will be CERN and most current SPEC users.
+
+\* Quantity: 500 cards expected in 5 years
+
+\* Priority
+
+1.  cost
+2.  performance
