45% Reduction in Non-Conformances
An aerospace OEM’s core Tier-1 suppliers were behind schedule and burning overtime. GPSI led the recovery — stopping forward scheduling, freeing capacity, and standing up a Corrective Action Board that cut non-conformances by 45%.
Engaged GPSI to support and lead the recovery of its core Tier-1 suppliers — and their sub-tiers — back to schedule.
Key Takeaways
- GPSI led full recovery of core Tier-1 suppliers back to the current schedule.
- Stopping forward scheduling and freeing machine capacity halved overtime from 20% to 10%.
- A new Corrective Action Board (CAB) limited repeat non-conformances.
- Switching old castings to hog-out machining cut non-conformances by 45%.
- Daily standups and war-room calls drove drawing revisions that saved hundreds of hours.
- A full lead-time data cleanse for OSP/OSM parts improved on-time delivery.
Scope of WorkWhat was the scope of work?
A major player in the Aerospace industry hired the Global Partner Solutions team to support and lead the recovery of their core Tier 1 Suppliers. The SOW consisted of:
- Full Recovery of the Suppliers to the current schedule.
- Perform load/capacity analysis at the tier 1 Supplier and Capacity audits at sub-tier level.
- Provide Source Inspection to limit non-conformities.
ChallengesWhat challenges did GPSI face?
- Load Hours were not 1 for 1; productivity percentages were used (capturing incremental improvements) and not shared by the supplier, making it difficult to understand “Actual Load Hours” across each machine.
- Some Machines were scheduled for 7/20 operations which led to no open capacity for additional recovery.
- High reliance on overtime – as high as 20% to meet Load/Hours – that led to Suppliers not able to sustain the level, resulting in missed targets.
- Suppliers were performing Forward Schedule practice – this led to behind schedule to customer PO.
- Lead times not accurate for OSP (Outside Processing) and OSM (Outside Machining) and did not reflect on the overall lead-time for parts.
- Supplier lacked visibility of actual number of Load Hours offloaded to each sub-tier supplier, with no Load and Capacity Analysis performed at sub-tiers.
- No Corrective Action Board (CAB) process existed.
Corrective Action Board (CAB): a governance process that reviews defects and non-conformances, assigns root-cause corrective actions, and tracks them to closure so the same problems don’t recur. No CAB existed before GPSI implemented one.
Activities & ResultsWhat did GPSI do?
- GPSI stopped the forward scheduling practice.
- GPSI advised and secured the procurement of an extra Lathe to help stop the 7/20 operation on some machines.
- Lowered the Overtime to 10%.
- Implementation of CAB process to limit the repeat non-conformances.
- Eliminated some old castings in favor of Hog out — this led to a reduction in non-conformances by 45%.
- Detailed Load and Capacity analysis performed at several OSP and OSM sub-tiers to better understand supplier capabilities.
- Implementation of daily tracking of hours planned vs hours achieved for each machine.
- GPSI introduced daily morning standups to discuss any issues from the previous shifts.
- Introduced daily war room calls between Suppliers and the client to leverage client’s expertise on complex engineering problems — leading to several Drawing Revs that saved hundreds of hours of redundant testing and processes.
- Data Cleanse – Leadtimes were corrected for every part that had OSM and OSP, resulting in improved OTD and customer satisfaction.
OSP & OSM: Outside Processing (OSP) and Outside Machining (OSM) are operations sent to external sub-tier suppliers — such as special coatings or machining. Inaccurate OSP/OSM lead times had distorted overall part lead-times until GPSI cleansed the data.
ImpactWhat was the impact?
Non-conformances down 45%, overtime halved, a Corrective Action Board in place, and corrected lead-times across every OSP/OSM part — improving on-time delivery and customer satisfaction. — Outcome of the GPSI Tier-1 supplier recovery
