  • 1.  Benchmark Target Changing for MRO Inventory %ERV ?

    Posted 05-04-2023 11:14 AM

    Should the Benchmark Target for MRO Inventory as % ERV change in the post-covid, disrupted Supply Chain environment we're in today?  Even with early warning from the effective use of Predictive Maintenance technologies, Spare Parts and Equipment are taking longer to acquire than the early warnings of failure provided by PdM, making larger inventories of spares a necessary strategy for equipment and process reliability.

    Short answer - probably, given the potential delay in access to spares.  However, a more important issue to be considered is the nature of your maintenance function.  If you're highly reactive, you need a lot of spares, since you don't know what's needed next. If you're more PM/PdM driven then fewer, since you have a greater understanding of what's needed and when, but your best position is one where you're very proactive about eliminating the defects that create the work, and need for spares.  Fewer failures = fewer spares, and when linked to a solid PM/PdM program, allows for better management of spares requirements, IF you run your storeroom like a business - clean efficient, quantities linked to use rates, etc.  I would hold the stores/purchasing manager and maintenance manager both responsible for inventory levels/turns, and, service levels (stock out rate).  It facilitates a more collaborative relationship, and better system-level result.  I hope this helps.
