Cycle Count

http://blog.kinaxis.com/2010/05/cycle-counting-101/

I was at an event last week where I met a guy who works for an electronics
contract manufacturer.  He was telling me about a physical inventory they
were doing at the plant.  Apparently the physical inventory was revealing a
lot of inventory discrepancies.  This surprised me because I knew the
company had procedures in place to do regular cycle counts.  As I dug a bit
deeper, I discovered some things that made it really easy to understand why
there were problems;

  1. The driver behind the cycle count was financial reconciliation.  The
  key was ensuring that the inventory values tallied to what was on the books
  in aggregate.  So, if part A was down a bit and part B was up a bit,
  overall, things balanced!
  2. There was no follow up to identify the root cause of the
  discrepancy.  And no changes put in place to prevent similar issues from
  happening again. In fact, the inventory clerks would simply adjust the
  inventory balance to reflect the correct values.

So… what’s wrong with this approach?  It’s all about the money, right?
Right. It IS all about the money.  However, how much money can you make if
you can’t make the parts you want to sell?  How much money can you make if
your profits are all eaten by the added expense of expediting?    An
incorrect inventory quantity on a component that costs a fraction of a cent
can prevent a multi-million dollar unit from shipping on time.    Take a
word of advice.  Get the finance guys out of the stockroom and change the
focus to true inventory accuracy.    A cycle count needs to ensure that the
right quantity of  the right part is in the right location.  The interesting
thing about focusing on inventory accuracy is that the financial accuracy
will improve automatically.  It’s win win!

The other problem with this company’s approach was that people were not
following up to determine the cause of the cycle count discrepancies.  In a
former life I used to support our inventory control staff as they tried to
figure out why their values weren’t tallying.  In many cases, the cause of
the error turned out to be systemic in nature;  Backflushing errors, BOM
errors, incorrect allocations, etc.  Fixing these prevented the same problem
the next time this part was made.  In some industries (electronics,
pharmaceuticals. etc) , where parts could have black market value,
establishing root cause is critical to ensuring that pilfering is caught and
dealt with quickly.

So what are some best practices for cycle counting?  Jeff Rose at Tomkins
Associates <http://www.tompkinsinc.com/>put together a very informative
guide<http://www.tompkinsinc.com/publications/monograph/monographList/WP-19_Cycle_Counting.pdf?monographID=WP-19>to
implementing cycle counting which outlines the goals, benefits and
steps
to implementing a world class cycle counting program.  In my opinion this is
a must read for anyone who manages inventory.
