Our Quality Assurance Pipeline
Quality is not a final check — it is embedded at every stage of the workflow. Our five-stage QA pipeline catches errors before they compound and ensures consistent accuracy across projects of any scale.
Contributor Vetting
Every contributor undergoes language proficiency testing, background screening, and a structured onboarding assessment before joining any project.
In-Task Quality Controls
Real-time quality signals are embedded throughout every task — including golden-set validation items, consistency checks, and automated anomaly detection.
Peer Review Layer
A dedicated tier of senior reviewers audits a statistically significant sample of all completed work, with 100% review on high-stakes or sensitive projects.
QA Lead Audit
QA leads perform final audits, resolve escalations, and produce per-project quality reports with inter-annotator agreement scores and error analysis.
Client Acceptance Review
Clients receive structured deliverables with full quality documentation. Rejection rates and revision cycles are tracked and fed back into process improvement.
Data Privacy & Compliance
Handling client data responsibly is a core operational requirement, not an afterthought. Our privacy practices are designed to meet the expectations of enterprise clients operating in regulated industries.
NDA & Confidentiality
All contributors, staff, and subcontractors sign binding NDAs before accessing any client data. Project-specific confidentiality agreements are available on request.
GDPR Awareness
Our data handling practices are aligned with GDPR principles — including data minimization, purpose limitation, and documented consent for all contributor-generated content.
Data Access Controls
Client data is accessible only to contributors and staff assigned to the specific project. Role-based access controls and audit logs are maintained throughout.
Secure Data Transfer
All data transfers use encrypted channels. We support client-specified secure transfer protocols and can work within client-managed infrastructure environments.
Data Retention Policy
Client data is retained only for the duration required to complete the project. Secure deletion is performed upon project completion or at client request.
Incident Response
We maintain a documented incident response procedure with defined escalation paths, client notification timelines, and post-incident review processes.
Contributor Standards & Ethics
The quality of our output depends entirely on the quality of our contributors. We invest heavily in contributor selection, training, and ongoing performance management — and we hold ourselves to ethical standards that protect both contributors and clients.
Fair compensation benchmarked to local market rates
Clear task guidelines and escalation paths for ambiguous cases
Regular calibration sessions to maintain annotation consistency
Transparent performance feedback and improvement support
Zero tolerance for data misuse or confidentiality breaches
Quality Commitment
Accuracy Guarantee
We stand behind our accuracy benchmarks. If delivered data falls below agreed quality thresholds, we remediate at no additional cost.
Transparent Reporting
Every project delivery includes inter-annotator agreement scores, error rate breakdowns, and a QA summary report.
Continuous Improvement
Client feedback is systematically incorporated into annotator training and guideline updates. We track improvement over project lifecycle.
Dedicated QA Contact
Enterprise clients are assigned a dedicated QA lead who serves as the single point of contact for all quality-related questions.
