Home/Verification Standard

What Wisfield commits to in writing

Wisfield does not publish client lists, logos or testimonials. What it offers instead is a standard you can hold it to, written into every statement of work and evidenced at every handover.

1. Written specification sign-off

   No build begins until every open question is logged, numbered and answered in writing.

2. Direct access to the principal

   The person who scopes your study is the person who builds it. No account managers, no hand-offs.

3. Independent third-party audit

   Every instrument is audited by an external firm that did not build it, and is paid for every defect it finds.

4. Documented test evidence

   You receive the test plan and its results, not an assurance that testing took place.

5. Controlled change log

   Every post-approval change is dated, attributed and re-verified before it reaches a respondent.

6. Data map reconciliation

   The delivered file is reconciled against the questionnaire, variable by variable, before release.

When something goes wrong

Any defect against the signed specification is corrected free of charge, including data reprocessing.

Verification catches almost everything. For the rare defect that reaches the field, the response is decided in advance:

1. You hear it from me first, within hours of discovery, not when the tables arrive.
2. A plain account of scope: which question, which respondents, which variables.
3. The fix, and options for the data: recode, flag, remove or top up, wherever possible.
4. A written incident note: the cause, and the change made to the process so it does not recur.
