Benefits
Inventory Reduction
Typically there is a 25% to 35% reduction in inventory. This is
accomplished through better scheduling of inventory; getting the
right material at the right time. Elimination of safety stock on
dependent demand items is also a key factor.

Note: There is also a one-time cash flow improvement from the
decrease in inventory.

= Cash flow improvement $ ________________
Purchasing cost reduction
Typically there is a 2% to 5% improvement in purchase costs.
Valid schedules allow purchasing people to spend most of their
time doing effective purchasing instead of expediting or trying
to get material in less than normal lead times. This also
provides purchasing people with accurate up-to-date projections
of usage by item for sourcing decisions, volume discounts, and
value analysis. Less paperwork is also a by-product.

Productivity improvements
Improvement in direct labor is typically 5% to 10% in fabrication
areas and 25% to 40% in assembly areas. This is a result of
fewer shortages, less frequent interruptions and short runs
because of expediting. "All" parts are available when scheduled
for assembly. In fabrication areas, there are minimal hot orders
and rush jobs that cause short lots, extra set ups, disruption
and inefficiency.
Annual direct labor $ ________________
x Percent improvement % ________________
= Annual direct labor savings $ ________________
Customer service
A 3% to 5% increase in sales is typical due to more on-time
shipments, improved quality, and reduced lead times. This is
usually accomplished with existing facilities. With better
scheduling, more of the right material is made available at the
right time and shortages are known further in advance so that
they can be prevented before they impact customer service.
