Commercial Vehicle Warranty Analysis: From 78 Days to Closure Within a 45-Day SLA
How Qualitiviss and QAI helped a German-based global commercial vehicle manufacturer manage four times the quality analysis volume at its Oragadam operation.
A longer warranty expanded the investigation window. The team needed a traceable path from open ticket to approved closure across product failures, manufacturing divisions and Tier suppliers—without losing human accountability for quality decisions.
Commercial vehicle warranty period
Volume of cases requiring analysis
Ticket closure, now within the SLA
Reported analysis and workflow processing speed with QAI
The 50× figure is a team-reported processing-speed gain for analysis and workflow handling within a case. It is separate from the end-to-end ticket closure result.
A five-year warranty quadrupled the analysis queue.
The manufacturer extended its commercial vehicle warranty from two years to five years. As the warranty period expanded, the volume of cases requiring quality analysis quadrupled.
An internally developed case tool existed, but opening a ticket, following up on investigation and closing its file remained heavily manual. One case could involve multiple product failures, manufacturing divisions and Tier suppliers. The warranty team had to establish traceability, assign each part of the investigation, follow actions and obtain human approvals.
At the higher volume, tickets previously took 78 days to close against a 45-day SLA.
One traceable workflow from open ticket to closed file.
Qualitiviss: quality case workflow
Product traceability, multiple failure issues, ticket status and ownership are managed together. Manufacturing division stakeholders and Tier suppliers receive the relevant work, giving the team a clear view of what needs investigation and who owns the next action.
QAI: analysis and workflow audit
QAI accelerates analysis and audits the workflow as cases progress. Manual tracking and coordination steps are automated, while decisions requiring intervention or approval still go to the responsible people before closure.
Track, analyse, approve, close.
- 01
Open and trace
Record a warranty quality ticket, its affected product and the multiple failure issues that may require investigation.
- 02
Assign ownership
Route the relevant work to manufacturing division stakeholders and Tier suppliers, with responsibility and status visible to the warranty team.
- 03
Analyse and audit
QAI helps process the case evidence and audits the workflow as the investigation moves forward.
- 04
Review and close
Bring decisions that require intervention or approval to the responsible people before closing the quality file.
Within the 45-day SLA at four times the volume.
The team brought quality analysis tickets within the 45-day closure SLA, down from the previous 78-day closure time, while handling four times the analysis volume.
| Outcome | Before | With Qualitiviss and QAI |
|---|---|---|
| Warranty quality analysis volume | Baseline | 4× baseline |
| Quality analysis ticket closure | 78 days | Within the 45-day SLA |
| Analysis and workflow processing | Manual baseline | Reported 50× faster with QAI assistance |
The team reports 50× faster processing for previously manual analysis and workflow handling steps with QAI assistance. This does not mean end-to-end ticket closure was 50× faster; that result is the change from 78 days to within the 45-day SLA.
A longer warranty needs stronger quality case governance.
A five-year warranty gives product failures more time to surface. The challenge is to investigate consistently, trace the affected product, involve the responsible divisions and suppliers, and close each file on time. At Oragadam, Qualitiviss and QAI helped the warranty team manage that work at greater scale, with faster processing and clear human accountability for quality decisions.
