The intake form got longer and the queue got shorter

# Self-authored for the EML case corpus (no external origin). The platform team
# rewrote its request form to capture what it actually needed, and the queue
# wait fell from twenty-one days to five. What else changed is computed below.
#
# The rewrite was sound. Every field was added because a real request had
# stalled for want of it; the form validates as you type rather than rejecting
# at the end; the fields are grouped so a requester can see what is left; and
# the wait is measured from submission to first action, on the platform team's
# own tracker, not estimated.
#
# The queue is the requests that were submitted.

the new intake form
  every field : added because a real request stalled for
    want of it, not because somebody wanted a report
  validation : as you type, not a rejection at the end
  the fields : grouped, so a requester can see what is
    left
  the wait : measured submission to first action, on the
    team's own tracker
  days off the wait : 16
  verdict : FASTER

  justifying each field from a stalled request is the
  part almost nobody does, and it is why the form asks
  for nothing decorative

what the wait is measured over
  the population : requests that were submitted
  what submitting now costs : 19 minutes, up 
    17
  requests a month that stopped arriving : 
    2150
  submissions abandoned part way : 
    1900 a month
  which is more than the completed ones by : 
    650

  a queue got shorter and so did the line of people
  willing to join it; the wait cannot tell those apart

the work that stopped being requested
  did the need go away : nothing here says so
  tools found in the estate that nobody requested : 
    74
  who supports those : whoever installed them
  do they appear in the queue : no
  do they appear in the wait : no
  what the platform team sees of them : the audit, once
    a year

null control - two fields to ask, the rest asked later
  requests a month : 3300
  submissions abandoned part way : 
    120
  queue wait, days : 7
  the team did not get slower; the requests that had
  stopped being made came back and joined the queue

what a shorter queue guarantees
  a submitted request is picked up in 5 days :
    exactly, measured to first action on the team's own
    tracker, 8 months
  the organisation waits less for what it needs : not
    addressed; 2150 requests a month stopped being made
    and 1900 a month are abandoned mid-form

raising the cost of joining a queue shortens it; the
measurement is over the people who paid, and the people
who did not are not slow, they are absent

Every field was justified by a stalled request, validation is live, and the
wait fell 16 days to 5 on the team's own tracker. Asking now costs 
19 minutes instead of 2, so volume fell to 3676 per ten thousand of
what it was, 1900 submissions a month are abandoned part way - 650 more than
are completed - and the last audit found 74 tools nobody asked for.
