01
Identity & Profile Checks
Respondent details are checked for profile fit, study eligibility, and consistency with the recruitment brief before entry.
Profile fitEligibilityConsistency
Quality
Quality controls built into every stage of fieldwork.
From eligibility screening and duplicate review to manual verification and delivery sign-off, Yamada Research keeps respondent data clean before it reaches your team.
Quality framework
A layered validation process designed to protect research data.
Integrity is engineered into how each study is planned, recruited, screened, monitored, and delivered. Every stage works to remove weak responses, duplicate participation, and uncertain respondent fit.
02
Screener Review
Screening responses are tested against quota needs, respondent background, and survey logic before a participant is accepted.

03
Duplicate & Speed Controls
Repeat participation, duplicate patterns, straightlining, and implausible timing are flagged before completes are counted.

04
Manual Validation
Healthcare, B2B, and other low-incidence audiences are verified by hand where a study calls for a closer check.

05
Fieldwork Monitoring
Source quality, quota movement, and field issues are tracked while fieldwork is live, so problems surface early.

06
Final Delivery Review
Completes are reviewed for QC signals and status consistency against the client specification before handoff.

Quality system
Built around respondent quality
Validation controls structured as an operations pipeline—not a post-field afterthought—so research teams can trust what enters their study.
Eligibility screening
Quota, methodology, and inclusion criteria applied before field entry.
Identity and profile checks
Credential and profile verification aligned to study risk level.
Duplicate and inconsistency review
Cross-touchpoint signals flagged before responses are released.
Manual validation where required
Analyst review for high-stakes or specialist audience requirements.
Transparent field updates
Progress, flags, and escalation paths communicated during live field.
Clean project closure support
Documented handoff and audit-ready records for procurement review.
Quality signals
A validation readout for every respondent
Each control surfaces as a clear signal, so your team can see exactly how a respondent was screened, verified, and cleared into field.

The Yamada Quality Layer
One pipeline from feasibility to delivery — not checks bolted on at the end
Each project runs through the same structured pipeline, built for agencies and insight teams that answer to end clients on respondent quality, not headcount alone.
Operating principle
Integrity starts at feasibility, not at delivery. Each stage hands the next a cleaner sample, so issues are caught while there is still time to correct them.
- 01
Recruitment
Sourcing across panels, networks, and specialist channels, matched to the study's eligibility criteria.
- 02
Screening
Eligibility filters, quota control, and methodology-fit checks applied before a respondent enters field.
- 03
Validation
Identity and profile verification, with respondent consistency confirmed across touchpoints.
- 04
QC Review
Analyst review of completes, flags, and anomalies, each closed with a documented resolution.
- 05
Final Delivery
Validated respondent records handed over with the traceability to stand behind them.

Quality promise
What you can hold us to — before sign-off
These are operational commitments, not marketing lines. They set how screening, QC, and handover are staffed when a study cannot carry weak data.
- 01
Respondent validation before fieldwork
Profile and credential checks scaled to study risk, run up front rather than patched after completes land.
- 02
Duplicate and fraud-risk checks
Device, behavioural, and cross-project signals flagged before a response is added to your counts.
- 03
Screening consistency review
Timeline and pattern analysis to catch speeders, straightliners, and answer paths that do not hold together.
- 04
Offline and online recruitment controls
Field protocols and remote quotas held to one QC standard across both modes.
- 05
Audit-ready project documentation
Every event from recruitment to delivery logged for procurement and compliance review.
