This has been kicked around at the Scrum Gathering and other
locations.
Almost all Scrum teams see benefits and report liking Scrum better
than what they were doing before.
However, a large number of teams (the 75% figure is pulled out of
Ken's orifice) /do not/ report a transition to high productivity,
that is, a 250% or greater improvement. Inspection by various
"experts", YT included, generally finds that the cause appears to be
that the team has accepted as "context" something that should in
fact have been changed.
The number is therefore apocryphal but it is pretty well accepted in
the Scrum community at large, at least as seen from my observation
post.
