An experience database is important to compare one’s own measurement data
with the measurements of others. In the area of functional size measurement there
is the International Software Benchmarking Standards Group (ISBSG) database.
Table1.3 shows the penetration degree of the methods and if there are data in the
ISBSG database available (investigations by Morris (2000)).
As can be seen from this table, only IFPUG function points, Mark II func-
tion points, and Full Function Points version 1 achieved signicant importance.
Since the COSMIC is an
