Three anonymized customer stories from active Wistwin deployments since 2024 — steel CO gas, pharma Schedule M, auto-ancillary IATF + OEE. Customer names redacted under mutual NDA. Two of these cases (steel + pharma) have public-disclosure authorization in progress for Q3 2026. The numbers below are verified, defendable, and traceable to plant-floor source data.
An integrated steel group operating across three plants — combined output 14 MTPA — was running quarterly handheld CO gas leak surveys per their PESO licence + Section 41B Major Accident Hazard protocol. The survey caught the obvious. What scared the Chief Safety Officer was the slow-growing leak between surveys. CO gas pipelines carry multi-crore liability. PESO inspection is annual. The plants run 24×7.
3 plants, 47 CO gas pipelines, 12 dispersion zones. Quarterly handheld surveys caught a leak in 2023 only after a worker fainted. The Chief Safety Officer wanted always-on monitoring before the next PESO licence renewal.
AssetTwin mapped every PESO-licensed asset. AviraTwin deployed a 2,847-node CO sensor mesh — fixed detectors at every pipe joint, valve, gland, dispenser. Pre-alarm trends, not just threshold alerts.
Year 1: 11 excursions caught between scheduled handheld surveys. Each was a slow-growing weld-joint or packing-gland degradation. Cumulative leak rates, not single-point breaches. Two of the 11 would have triggered evacuation if undetected for another shift.
PESO licence renewal: zero NCRs across 3 sites. Industrial All-Risk insurance premium reduction at renewal. Board-level safety report now shows live LTIFR + near-miss data, not a quarterly snapshot. ₹14.8 Cr value in Year 1 alone.
"The handheld survey is a snapshot. AviraTwin is the movie. Both have their place — but only one is on at 3 a.m. when the night shift is short-staffed."
A listed Indian pharma manufacturer running multiple formulations + API plants across the Hyderabad cluster, with a sterile Annex 2 line exporting to USFDA-regulated markets. Schedule M revised 2024 had just been gazetted. The framework jumped from ~340 controls to 1,247. ALCOA+ data integrity moved from "good practice" to non-negotiable. The Quality Head had 9 months until the first cycle audit and a binder system that wouldn't survive scrutiny.
Schedule M revised 2024 expanded from ~340 to 1,247 controls. Paper batch records that didn't reconcile with electronic records became findings. The Quality Head was 9 months from the first CDSCO cycle audit with no path forward on continuous evidence.
10-week pilot. AssetTwin imported paper batch records via OCR. TrusTwin's pre-loaded Schedule M framework mapped each control to specific equipment, SOPs, batch records. AviraTwin covered the Annex 2 cleanroom (particle, HVAC, pressure differential).
First Schedule M revised 2024 audit cycle: TrusTwin generated the audit pack on demand. Every control's PASS/DUE/NCR status, evidence linkage, drill-down to source data, CAPA history. PDF for the inspector. Structured XML for the regulator. Audit prep dropped from 40 hours to 4.
Indian Schedule M's ALCOA+ alignment to 21 CFR Part 11 meant the same data layer satisfied both regulators. Six of seven plant audits closed with zero NCRs. The seventh had two minor findings, both closed within 30 days. USFDA inspection dossier prep time fell similarly.
"For the first time, the inspector wasn't waiting on us to find evidence. The evidence was already on screen. That's a different conversation. That's the conversation Schedule M was always meant to be."
A Tier-1 auto-ancillary supplier in Pune-Chakan — machined and assembled components for five major OEMs in parallel. Maruti SQA, Tata SQAR, Mahindra MSURE, Hyundai HSCS, plus one Stellantis brand. Each OEM ran quarterly supplier audits. Plus the annual IATF 16949 surveillance audit. The Customer Quality Engineer's calendar was 60% supplier audits. The plant's OEE was stuck at 73% because nobody had time to fix root causes — they were too busy preparing for the next audit.
Each OEM ran its own portal — Maruti SQA, Tata SQAR, Mahindra MSURE, Hyundai HSCS, plus the Stellantis CSR template. Each demanded different formats. The Customer Quality Engineer maintained 5 parallel Excels. IATF surveillance audit prep ate another 3 weeks. OEE was the casualty.
8-week pilot. AssetTwin mapped every CNC, fixture, gauge. SmarTwin live-streamed OEE per cell. TrusTwin loaded the IATF 16949 framework + 5 OEM customer-specific templates. AIAG Core Tools (FMEA, MSA, SPC, APQP, PPAP) ran on live plant data — not as spreadsheets.
When OEM auditors logged into their respective portals, the live OEE / FPY / lot-genealogy / FMEA data was already there. Quarterly audit prep dropped from 3 days per OEM to a 2-hour generation cycle. PPAP submissions for engineering changes compressed from 3 weeks to 2 hours.
IATF surveillance audit + 5 OEM quarterly audits over 12 months — all closed clean (0 NCRs). With audit prep no longer monopolising the Quality team's time, they finally addressed the OEE root causes that had been parked. OEE rose 11 points — from 73% to 84%.
"We didn't realise how much of our quality team's time was being spent re-formatting the same data for five different buyers. The first quarter on Wistwin, my team did real root-cause work. OEE moved 11 points. That came from time, not capex."
Every number cited is from an Indian plant deployment since 2024. No US / EU benchmarks dressed up as Indian. No simulation results. No analyst projections. Just plant-floor data.
Every metric — 11 incidents, ₹14.8 Cr, +11 OEE points — has audit-grade traceability. We can walk a reference customer or your assurance partner through the underlying plant logs.
Names redacted until customer authorization for public disclosure. Industry, region, plant scale, and module deployment are all real. The CO gas steel deployment is one customer, three plants. Two cases (steel + pharma) have authorization in progress for Q3 2026.
Take the DMM Check™ — 4 minutes, 12 questions, and you'll have a benchmark + top-3 module recommendation tailored to your industry and plant size. Then we'll set up a reference call with one of the customers above (under mutual NDA).
