Perfect coordination means that cutsheets 1 through 600 are
used for fabrication in numerical order, resulting in spools 1
through 600 arriving at the site in numerical order. Similarly,
work areas 1 through 15 are prepared in numerical order, so that
installation of spools 1 through 40 starts without delay as soon
as area 1 is ready, installation of spools 41 through 80 starts as
soon as area 2 is ready, and so on.
