This research explores the effects of customer wait time CWT and fill-rate on equipment operational availability AO using consumable repair parts requisition data from Marine Corps mechanized units to determine 1 the relationship between CWT, fill-rate, and AO and 2 if the systems reliance on fill-rate as the primary indicator of supply chain performance adversely affects AO. This study also captures observations on the quality and scope of Ground Combat Support SystemMarine Corps GCSS-MCdata. Analysis methods include linear regression techniques and a categorization model developed specifically to compare supply chain outcomes reported by CWT versus those reported by fill-rate. This study concludes that both fill-rate and CWT are important measures, but neither is sufficient as a single indicator of supply chain performance. The reliance on fill-rate alone currently results in misreporting of supply chain outcomes between 2040 of the time. These findings support policies that balance inventory performance with supply chain responsiveness, focusing efforts on items with long CWTs. The data also suggests logical CWT standards that differ from current policy. The scope and quality of the GCSS-MC data indicate that data collection processes could be further automated and focused on the drivers of days-dead-lined.
