Rigorous quality assurance processes ensuring every data point meets the highest standards of accuracy and reliability.
At Data Driven Global, quality is not an afterthought — it is embedded in every stage of our research process. Our multi-layered QC framework ensures data integrity from field to delivery.
Real-time GPS verification ensures intercepts occur at approved locations. Interviewer performance is monitored through ride-along supervision, back-checks, and audio recording review. Referral chains are tracked and validated for authenticity.
Placement studies undergo rigorous monitoring including pre-placement inspections, mid-study check-ins, and post-study retrieval verification. Participants are screened and matched against strict quotas, with daily progress tracking and photo documentation.
Every mystery shopping visit is validated through photo evidence, GPS tracking, timestamp verification, and detailed report review. Independent QC auditors verify 100% of reports against predefined quality benchmarks before client delivery.
Central location tests are supervised by trained moderators and facility managers. Respondent identity is verified, tests are video recorded where permitted, and data is reviewed in real-time. All deviations are documented and addressed immediately.
Exit interview data is cross-checked against location logs and time stamps. Supervisors conduct random spot checks and re-contact a percentage of respondents to verify participation and response accuracy.
CATI operations feature live call monitoring, automated call recording, and real-time supervisor feedback. Dialer logs are audited, and a minimum of 20% of completed interviews are back-checked by QC supervisors for consistency and accuracy.
Before any data collection begins, all research instruments are reviewed, field teams are briefed, and test runs are conducted to validate the setup. Sampling plans are verified against client specifications to ensure proper targeting.
Our centralized monitoring team tracks all field activities in real-time using GPS tracking, time stamps, and live data feeds. Any anomalies are flagged instantly, and field supervisors are alerted for immediate intervention.
A minimum of 20% of all completed interviews are back-checked via telephone or in-person re-contact. Respondents are asked key questions to verify their participation and the accuracy of their responses.
Collected data undergoes automated validation checks for logic, consistency, and completeness. Outliers, skip pattern violations, and suspicious response patterns are flagged and reviewed by the QC team.
Before delivery, a final audit is conducted by the QC manager. Only data that passes all quality thresholds is released to clients, accompanied by a quality assurance certificate and comprehensive documentation.
