Survey Scripting · Independent Audit · Data Integrity
The questionnaire is an intention. The script is the study.
Wisfield Survey Engineering programs, verifies and stewards survey instruments for research agencies and insight teams whose findings will be relied upon. Every skip, quota, terminate and data map is specified, built and independently verified before a single respondent sees it, on timelines most shops only meet by skipping that step.
- i.One principal programmer. No account managers, no hand-offs, no queue.
- ii.Every build audited by an independent firm that is paid for every defect it finds.
- iii.Fast without shortcuts: a written quote in two business days, an audited test link in three.
Why survey scripting is not a commodity
Sampling is reviewed by statisticians. The questionnaire is reviewed by the client. The analysis is reviewed by the team presenting it. The script, the one artefact that decides who is asked what, is often reviewed by no one but the person who wrote it.
| Scripting failure | Consequence in the data | Typically discovered |
|---|---|---|
| Skip logic leak | Respondents answer questions they should never have seen; every downstream base is wrong. | At tabulation |
| Quota misconfiguration | Cells overfill or close early; sample costs rise and the achieved mix is distorted. | Mid-field, or not at all |
| Terminate misrouting | Qualified respondents are screened out, or unqualified respondents admitted. | Rarely |
| Piping and text-fill errors | Respondents evaluate the wrong brand, product, condition or concept. | After delivery, by the client |
| Randomisation faults | Order bias enters a monadic, MaxDiff or conjoint design. | Usually never |
| Data map divergence | Variables do not match the questionnaire; trackers break wave on wave. | At the next wave |
None of these errors announce themselves. All of them are preventable at the scripting stage. Almost none of them are recoverable afterwards.
Wisfield would rather lose the project than field an instrument it cannot stand behind.
