Case study 06 · Quality Transformation

From a 25% Error Rate to a Sustainable Quality System

Two-stage QA, root-cause discipline, and a living knowledge base.

A programmatic trafficking process with a 25% error rate and 75% SLA adherence was rebuilt around standardized checks, centralized work tracking, dedicated QA, and a closed improvement loop.

The operating problem behind the symptoms.

Campaign setup errors were frequent, service levels were unreliable, and recurring defects were not being learned from. Work was manually tracked, shift coverage did not follow demand, and no common QA or root-cause framework existed. The issue was not one bad checklist—it was the absence of a quality system.

  • No centralized QA structure or defect taxonomy.
  • Manual work tracking and poor prioritization.
  • Repeat errors without systematic root-cause action.

A practical transformation sequence.

The work was organized around a small number of operating choices that could be governed, measured, and repeated—not a collection of disconnected initiatives.

1

Create two-stage quality control

Introduced campaign-specific checklists, post-setup QA, and campaign-manager validation before go-live.

2

Make work visible

Implemented ticketing for ownership, status, priority, SLA tracking, and audit history; then aligned shifts to demand patterns.

3

Build root-cause discipline

Categorized defects across human, knowledge, system, and process causes, with regular analysis and owned corrective actions.

4

Turn defects into learning

Created a dynamic knowledge base, frequently-made-error log, annotated guidance, and retraining triggered by QA and RCA findings.

What changed in the day-to-day model.

Before

  • Ad hoc checks
  • Manual request tracking
  • Recurring defects

After

  • Two-stage QA
  • Auditable ticket workflow
  • RCA-to-training feedback loop

Results that connect to the intervention.

Repeat errors became actionable

Defects were tracked by cause and addressed through training, process revision, or tool improvement.

A sustainable feedback loop

QA, RCA, knowledge management, and training became one connected operating rhythm.

A reusable quality blueprint

The model improved client confidence and became a reference for other campaign operations.

What made the change durable.

  • Quality improves when defects are categorized consistently and owned cross-functionally.
  • A knowledge base should be fed by real failure patterns, not written once and forgotten.
  • Capacity planning and quality planning must be connected.
