There
  are
  parameters
  that
  we
  can
  use
  to
  understand
  and
  measure
  a
  system.
  In
  classic
  non-
  violent
  communication,
  we
  know
  the
  needs.
  These
  represent
  the
  parameters
  of
  inner
  life
  and 
  show
  what
  a
  person
  needs
  in
  a
  certain
  context.
  In
  NVC-plus,
  however,
  we
  do
  not
  want
  to 
  assess
  the
  personal
  needs
  of
  a
  person,
  but
  the
  abstract
  requirements
  of
  a
  system.
  Why
  is
  that 
  important?
  If
  you
  want
  to
  build
  a
  clock
  together,
  then
  the
  requirement
  parameters
  for
  a 
  workshop,
  for
  example,
  are
  derived
  from
  the
  goal.
  It
  does
  not
  need
  to
  be
  large,
  but
  it
  must
  be 
  sufficiently
  clean.
  The
  tools
  must
  guarantee
  appropriate
  or
  at
  least
  sufficient
  precision.
  In 
  management,
  this
  is
  called
  a
  KPI
  - 
  "Key
  Performance
  Indicator",
  i.e.
  key
  figures
  that
  can
  be
  used 
  to
  determine
  the
  performance
  of
  activities
  In
  NVC-plus,
  however,
  there
  are
  not
  only
  design 
  parameters,
  but
  parameters
  for
  all
  fields
  of
  the
  Four-Step-Circle.
  The
  approach
  was
  already 
  outlined
  by
  Prof.
  Nossrat
  Peseschkian
  with
  the
  Differential
  Analytical
  Inventory
  (DAI),
  who 
  differentiated between the parameters of the path and those of the goal.
