I'm not sure I can manage to interpret that number...

if the IETF had been a single person, devoting its attention to one RFC at
a time, the numbers would indicate that the IETF needed 0.126 months of
attention to produce an RFC in 1999 (taking 19 months to produce 157 RFCs)
, but 0.172 months of attention to produce an RFC in 1995 (taking 10.5
months to produce 61 RFCs)?
This of course ignores the fact that most of the work in producing the year
2000 RFCs was done in 1999, and certainly impacted work on the 1999 RFCs,
which were mainly produced in 1998, and so on back the chain....
besides, what does it mean for an entity to work 19 months in one year?
If instead we *multiply* the number of RFCs by the time needed to produce
them, we should get something indicating the amount of attention directed
at the IETF doucment-producing effort:
Year RFCs Delay Effort Largest IETF Effort/attendee Watchers
months RFC*mn RFCmonth/person
1993 31 5.5 170.5 638 (Columbus) .26 44.9
1994 80 8.4 672.0 1079 (San Jose) .62 19.2
1995 61 10.5 640.5 1007 (Dallas) .63 18.8
1996 96 12.4 1190.4 1993 (San Jose) .59 20.1
1997 103 14.4 1483.2 1897 (Washington) .78 15.3
1998 147 19.6 2881.2 2124 (Orlando) 1.35 8.8
1999 157 19.8 3108.6 2379 (Washington) 1.30 9.1
2000 158 24.2 3823.4 2810 (San Diego) 1.36 8.8
there may be SOME evidence for the "adding more people to a late project
makes it later" theory - but the main point may be that unless we know what
theory we want to test, it's a bit dangerous to multiply things together...
....for another interpretation of the numbers, you can invert the
effort/attendee, multiply by 12, and call it "number of people looking at
each document being written", and argue from there that our problem is that
we have too *few* people pushing at each individual document.... in 1993,
there were on the average 14 RFC-projects going on, each with 45 people
watching it; in 2000, there were 318 projects going on, each with less than
9 people watching it.
Of course, this probably has *very* little to do with root causes or
remedies - if we were to keep the same attendance, but could finish
projects faster, we would have more eyeballs free to look at the documents
we *are* working on.
But still, it'll be fun to look at what these random multiplications do to
the 2001 and 2002 numbers :-)
