So is windows so why then do they use 1960’s green screens. Every study done shows a GUI interface increases productivity by 25-27% so this guys cripple their own companies.
No one is talking about bleeding edge put into production but most technology 10-15 years old won’t get used while they won’t uses cars from that era.
I have been in too many meetings where they say the training costs far “out-weigh the cost benefits”
Get on IBM-Main you can read it there - they will tell you themselves. So, it is there stupid comment you are critical of.

I have to take exception with that statement. GUIs slow down data entry. Especially for heads-down data-entry applications and warehouse/distribution center automation applications.
For increased data-entry productivity and warehouse automation apps, I’ll take a green-screen 5250 application over a GUI windoze application any day.
Because those green screens contain all the data in a format the user finds acceptable. Not every user needs pretty pictures and bouncing balls to do his job. Some are capable of reading.

Maybe a 25 percent (imaginary) improvement in productivity doesn't offset the millions necessary to turn 3270 SNA datastreams into purty pitchurs for illiterates.

Maybe that's because the training costs far outweigh the benefits.
