Opportunities
in inventory
by
Dave Melhus
By
now, your company’s January financial results are history. If your
profits are hitting the mark, your MRO budget is likely flying under
the radar screen. If not, it’s a matter of time before your budgets
are scrutinized. No one will remember or care if the maintenance and
tooling budget reflected a reduction in expenses while production was
increasing. It’s your job, suck it up, and manage it.
The question is: Will you muscle your budget
with baling wire and by digging through the boneyard, or turn to
process improvement?
This
column focuses on turning MRO inventory into “free budget
dollars.” If your company treats MRO supply purchases as an expense,
then every dollar not replenished is a dollar saved on your expense
budget. I’ve found that a change in your inventory logic is a quick
method of delivering impressive results.
You
probably think that you already improved your inventory system. Maybe
you developed a minimum/maximum reorder point, consigned various
commodities or even had vendors manage select commodity types. All are
good first steps, but did you implement them with an overall strategy
in mind? Or, does the strategy need fine-tuning?
Consider
how the following tactics might benefit your budget.
Assuming
your company has implemented some sort of supply strategy, ask
yourself, who was involved and what was the purpose? Was it to reduce
administrative time, number of suppliers, pricing, inventory dollars,
or all of the above?
Did
the group view the change as a project and, therefore, approached a
solution as “one size fits all” vs. considering an 80/20 method?
I’ve seen countless times when the tactical approach (supplier
reduction, consignment and vendor-managed inventory) overshadowed the
combined company objectives (less cost, less inventory, increased
delivery flexibility and reduced administrative time).
Sometimes
team makeup also influences the approach. For example, a maintenance
buyer may value administrative time and 100 percent assurance of part
availability vs. inventory turns while a corporate buyer values
supplier consolidation and price vs. inventory and time.
Quick
improvements are prevalent if you take the time to assess the workings
of your current supply system. Don’t take my word; go to the gemba.
Walk your supply aisles or, if you must, scan the inventory report.
Where are your dollars? Select a dozen or so items with a relatively
high on-hand dollar value. Compare the lead time of the item with the
estimated number of days on hand. There’s seldom a relationship
between the quantities on hand vs. the time to replenish the stock.
The difference between estimated daily/weekly usage and replenishment
time (plus a safety stock level) is roughly your budget opportunity.
Do
you have other parts within those selected commodities? If so, your
opportunity is multiplied.
How
does the acceptable level of downtime relate to the quantity on hand?
Do you have a motor or shaft on hand even though the total downtime
involving a motor or shaft is several days and the supplier has
next-day delivery options?
Have
you challenged your suppliers’ lead times? If you commit to buy
items exclusively from a supplier, would they stock your inventory?
How
many just-in-case items are on hand?
In
addressing these areas, it’s easy to respond that you “can’t do
it . . . just because.” But, these are opportunities to lower
inventory and free up budget dollars. If you don’t find a way to
overcome the “can’t,” enjoy muscling your budget.
Another
area many companies discover as advantageous are consigned or
vendor-managed inventory (VMI) programs. Significant cash and expense
(supply and administrative) opportunities are typically realized. A
huge advantage is in creating organization out of chaos. The biggest
mistake is that companies believe it’s OK to pass broken processes
and inefficiencies onto the supplier.
Aggressively
increasing the expectation of price, delivery and pull concepts with
your supply partners yields extra benefits. Failure to do so results
in future price increases.
Waste
that typically creeps back into these systems are uncontrolled
inventory at the workstations, failure to reduce transactional
activities, not setting lead-time expectation, or not linking
replenishment to usage. Jointly establishing a continuous improvement
plan with your suppliers includes topics such as part rationalization,
lead-time reduction, alternative supply and administrative time
reduction.
Whether
it’s your systems or those administered by your suppliers, waste
exists. It’s significant, and it’s up to you to address.
