Digital Survey Systems

Reliable digital instruments designed for complex research.

The problem we solve

Complex instruments fail quietly. Broken skip logic, missing constraints and untested preloads produce data errors that only surface after fieldwork has ended.

Scope — what is included

SurveyCTO programming from an approved questionnaire
Questionnaire logic, constraints and relevance conditions
Preloading, repeat groups and roster handling
Multilingual forms, structured testing and deployment

Methodology

XLSForm programming
Automated validation rules
Structured form testing
Version control

Deliverables

Deployed digital questionnaire
XLSForm source files
Test matrix covering logic paths and constraints
Codebook of variables and value labels
Technical handover documentation

What we need from you

Research decisions stay with your team. To deliver this work we need you to:

Approve final question wording, response options and translations
Provide the survey server account or authorise one to be set up
Sign off on the test matrix before deployment

Illustrative workflow

A synthetic example, included to show how the work runs. It is not a past engagement and does not describe a real client.

A household instrument needs rosters, two languages and preloaded panel identifiers.

1Program the instrument as an XLSForm with constraints on every numeric field
2Preload panel IDs and prior-round values for verification
3Run the test matrix across every logic path and record results
4Deploy, then hand over source files and a codebook
