hold parts on a consignment basis
not paying too much to expedite orders
improving your max/min process.
Also, ask these questions:
Do you have too much safety stock
because you don't trust your process?
Is your parts coding sufficient or is it
difficult to specify parts?
Do you review your inventory to know
what you really have?
Do you have a defined parts process,
but roles are not clear or ignored?
Do you work to reduce the time that
you hold inventory (better align purchasing and usage)?
Do you have too many stock-outs?
When stock-outs exceed about 5%, employees will start hiding away parts since
they don't trust the stockroom process.
Do the people ordering/buying parts
have accountability for the parts budget or
a related spend metric?
Are there too many uncontrolled parts
sitting around on the plant floor, held by
various departments? Most plants have a
parts/old machine "boneyard" for just-incase needs.
Short term, you need to buy and store
fewer MRO spare parts. Long term, you
need to put a control strategy in place to
sustain your improvements. You should
start by doing a spare-parts tally of all of
your cumulative inventory (documented
and categorized in stores and miscellaneous storage areas throughout the
facility), what's hidden away by trades/technicians, and what engineering hides away
because purchasing is using a lowest cost
versus life-cycle costing approach. Then
understand what current parts are really
Misalignment leads to increased vibration, premature seal,
belt or bearing failures and increased power consumption.
There's no excuse to let misalignment cost you money.

needed based on equipment criticality,
replacement delivery times, and minimum/
maximum levels.
Company personnel with whom I have
spoken and worked in the past have been
able to reduce their spare-parts inventory
from a few million dollars to more than
$50-million dollars. Regardless of how big
your opportunity is, proper spare-parts
management can optimize uptime and
costs, while paying for your PdM/CBM
monitoring equipment and training. EP
