a primary communication group effort fighting off distributed computing
and client/server was SAA (I've periodically mentioned senior disk
engineer getting talk at annual worldwide internal communication group
conferencing and opening with the statement that the communication group
was going to be responsible for the demise of the disk division ...
among other things the disk division was seeing drop in disk sales with
data fleeing the datacenter for more distributed computing friendly
platforms ... and communication group veto'ing all the solutions the
disk division would come up ... the communication group had strategic
"ownership" for everything that crossed data center wall).

"Father of SAA" no relation ... and the executive put in charge of doing
SAA in the early 90s ... I had worked with many years earlier on 138/148
microcode assist and would periodically drop by his office on top floor
of somers and ridicule SAA.

part of the issue was we had come up with 3-tier architecture ...
initially written into response for large, distributed, super-secure
government program ... and then out making pitches to customer
executives ... and getting lots of arrows in the back (and other FUD)
from the communication group. past posts mentioning 3-tier (and SAA)
http://www.garlic.com/~lynn/subnetwork.html#3tier

part of the issue was 3tier was all tcp/ip (and not SNA).

at the same time SAA was kicked off, the communication group was also
out distributing a lot of misinformation inside the corporation about
how SNA could be used for the the NSFNET backbone (precursor to modern
internet). old NSFNET backbone email

and past posts 
http://www.garlic.com/~lynn/subnetwork.html#nsfnet

and other misinformation that if the internal network wasn't converted
to SNA, the internal network would stop working. internal network old
