Exxon Mobil
Exxon-Mobil uses SMS for it's MRO inventory in Nigeria.  Over 200,000 active items are processed each week with a portion falling into the "slow moving" category.  With a massive database like this, there would be a lot of room for excess spending.  Not so with SMS!  Active items are easily forecast and replenished by exception reporting.  Items with little activity often have no forecast, yet SMS can determine an appropriate level to stock for use in the coming year.  The Initial Spares function within SMS helps engineers set the proper parameters at the time the item is created.  The SMS "slow moving" logic is the only approach on the market today that properly sets spare part levels for inventory.

Even for items with no activity in the past 5 years, SMS can set spares levels through the use of "number in service" and manufacturer's "failure rate".  For items with even a little activity, SMS bases a calculation on service level and cost.  For the bulk of these items, SMS is used to update the Stock Status database for reorder point data.  Most items in an MRO inventory are already overstocked, so there should be little ordering initially.  SMS helps reduce the spares levels so that an inadvertent order will not reload excess inventory again.

SMS is also useful for identifying databases inaccuracies.  Things such as Past Due Orders (that are really data errors) pop out at the planner through SMS reporting.  Improper cost data, history figures and excess ordering pop out as well.  Data review is often a big part of SMS use for MRO operations.

Emeka Owubokun says "SMS was easy to implement and only two IT staff worked on the interface.  It runs easily and brings our attention to continuing excesses.  By replacing our "MIN" and "EOQ" values with SMS we also prevent future over-spending.  SMS is a valuable tool."
