2023 operational efficiency study, 14 Indian automotive OEM assembly facilities: 62% of total stoppage duration is expert access latency, not fault complexity. The repair takes 35 minutes. Getting the expert to the fault takes the rest.
Problem Framing
Access latency, the time between fault occurrence and expert intervention, is the largest recoverable component of stoppage duration in Indian automotive manufacturing. It is rarely measured as a distinct metric. It appears as 'total stoppage' in OEE data. The root cause is attributed to the fault. The real cost driver is the workflow that takes 74 minutes to connect a person 180 metres away.
Core Insight
A 300-metre assembly line at 45 JPH loses ₹55,000–90,000 per stoppage hour. 62% of a 4.2-hour average stoppage is recoverable access latency = 2.6 recoverable hours per event = ₹1.4–2.3 lakh preventable per event. At 3 events per week over 48 production weeks: ₹2–3.3 crore per line per year from a category most plants don't track separately. Remote assistance collapses the 74-minute access time to under 3 minutes.
Breakdown
The timeline math: Fault at 10:14. Alarm raised 10:16. Supervisor acknowledges 10:29. Expert arrives 11:08. Repair starts 11:11. Complete 11:46. Total downtime: 92 minutes. Fault time: 35 minutes. Recoverable: 57 minutes.
Remote assistance intervention: Fault at 10:14. Technician connects remote expert at 10:17. Guided repair starts 10:19. Complete 10:54. Downtime: 40 minutes. A 57-minute recovery from one workflow change.
No proximity constraint: The expert can be in another building, another city. The connection is instant.
Real-World Application
AjnaVidya remote assistance deployed across 4 critical lines at a Chennai transmission assembly plant. Average stoppage duration reduced from 4.6 to 1.4 hours. Annual unplanned downtime cost reduction: ₹4.6 crore. Expert coverage ratio improved from 1:1 to 1:3.5 lines, same headcount, 3.5x the coverage.
Actionable Takeaway
Extract your stoppage logs. Measure 'fault occurrence' to 'repair start.' That delta is your access latency, almost certainly your largest recovery opportunity.
