Webinar - How to uncover and eliminate hidden costs in your factories
Uncovering opportunities for improvement in your factories
Every day, factories consume resources—such as time and capacity—to produce and deliver orders and satisfy their customers.
...Yet, resources are also consumed daily by the system itself to compensate for internal inefficiencies, such as poor quality, overproduction, or issues with manufacturability.
These issues consume—among other things—operator hours, machine hours, floor space, cash, management attention, and available capacity.
Because this often does not appear clearly in management reports, the concepts of "hidden costs" or the "hidden factory" have emerged:
a portion of capacity is wasted by failing to get things right the first time and by not producing exactly what the customer ordered.
Some studies estimate that this wasted capacity can amount to as much as 40% of a factory's total capacity.
In an environment driven by the race for competitiveness, identifying and eliminating these costs is therefore essential.
