Why
does
the
theory
of
constraints
advocate
that
a
manager’s
attention
be
directed
to
the
bottleneck
of
a
process?
points
It
is
useful
to
lower
the
utilization
of
the
bottleneck.
The
bottleneck
has
considerable
influence
on
the
average
flow
rate
of
a
process.
@
It
is
important
to
minimize
the
buffer
inventory
in
front
of
the
bottleneck.
First-come-first-served
scheduling
of
jobs
at
the
bottleneck
ensures
that
all
jobs
have
the
same
expected
waiting
time
befor
they
are
processed
at
the
bottleneck.
