14. Productivity soars when a
computer and its users interact at a
pace (<400ms) that ensures that
neither has to wait on the other.
In 1982 Walter J. Doherty and Ahrvind J. Thadani
published, in the IBM Systems Journal, a research
paper that set the requirement for computer response
time to be 400 milliseconds, not 2,000 (2 seconds)
which had been the previous standard. When a human
being’s command was executed and returned an
answer in under 400 milliseconds, it was deemed to
exceed the Doherty threshold, and use of such
applications were deemed to be “addicting” to users.
