Abstract
Drafting-cycle times can be
reduced significantly through
-
reduced waiting queues
through improved drafting
planning, coordination, and
accountability;
-
reducing the number of draw,
check, and correct cycles with
improved drafting quality;
-
improved drafter and checker
productivity; and
-
improved information flow to
drafting.
A drafting-process map with
associated timelines will identify the
source and duration of the waiting
queues and other non-value-added
activity. Corrective actions can then
be implemented to reduce queue
(idle) time through improved scheduling
and coordination of work flow.
A typical target for drawing-cycle-time
reduction is to reduce the
project’s start to submittal milestone
by at least one to two weeks. A more
aggressive target is to reduce the time
by half. Similar gains can be achieved
in shop-ticket-cycle time.
