End-to-End Research Data Services

From complex survey questionnaire authoring and server provisioning to live field QA and reproducible statistical deliverables.

Platform Engineering

CAPI Programming & Deployment

We build, configure, and administer secure Computer-Assisted Personal Interviewing (CAPI) applications across leading mobile platforms. Designed specifically for offline field resilience in remote regions of Myanmar and Southeast Asia.

Mobile CAPI Architecture: Field Enumerator, Offline Storage, Secure Cloud Server, and Supervisor Real-time Monitoring

Key Deliverables & Capabilities

  • Server Architecture & Role Management: Secure cloud server setup, enumerator account provisioning, and access permissions.
  • Offline-First Field Optimization: Zero-connectivity data storage, encrypted local caching, and reliable submission sync.
  • CATI & Telephone Survey Setup: Call-log tracking, disposition codes, and automated callback scheduling.

Logic Architecture

Advanced XLSForm Development

Transform complex, multi-page paper questionnaires into fluid, error-proof digital mobile forms. We architect sophisticated skip logic, dynamic calculations, and multi-language scripts.

Cascading Filters Regex Patterns Dynamic Rosters Myanmar Unicode

Key Deliverables & Capabilities

  • Myanmar Administrative Cascades: Standardized 3-tier selection (State → District → Township) with verified P-codes.
  • Nested Repeat Rosters: Complex household member rosters with cross-referencing loop calculations.
  • In-Form Data Validation: Mutual exclusivity checks, range boundaries, and regular expression constraints.

Quality Assurance

Data Quality & Field Monitoring

Catch field errors while enumerators are still deployed. We architect daily automated audit pipelines, outlier detection routines, and supervisor error-log tracking frameworks.

Daily Audits GPS Verification Duration Checks Error Logs
Monitoring and Evaluation in Food Security & Nutrition - Research Data Quality

Key Deliverables & Capabilities

  • Daily Field Submission Audits: Automated validation reports flagging missing values, logic skips, and duplicate IDs.
  • GPS & Duration Anomaly Tracking: Detection of speeders, clustered submissions, and spatial deviations.
  • Supervisor Feedback Loops: Rapid actionable error logs enabling prompt field callbacks.

Data Pipelines

Survey Data Processing

Turn messy raw mobile CSV/Excel exports into structured, fully labeled, and weighted research datasets using reproducible SPSS and Stata syntax pipelines.

SPSS Syntax Stata .do Files Weighting Codebooks

Key Deliverables & Capabilities

  • Automated Recoding & Cleaning Syntaxes: Reproducible `.sps` and `.do` scripts with full syntax audit trails.
  • Multiple-Response Set Restructuring: Binary indicator creation, value labeling, and dichotomous mapping.
  • Variable Dictionaries & Codebooks: Comprehensive metadata documentation ready for institutional archival.

Common Inquiries

Frequently Asked Questions

Practical answers to common technical and procurement questions regarding our CAPI, QA, and statistical services.

We provide full development and server support for KoBoToolbox, ODK Central, SurveyCTO, SurveyToGo, and CSPro. We also assist with platform migrations (e.g., transitioning legacy paper or CSPro systems into modern KoBoToolbox/ODK Central workflows).

Yes. We translate Word or PDF questionnaires into fully validated XLSForm architecture, incorporating cascading geography, skip patterns, constraint validations, and bilingual Myanmar Unicode scripts with complete pre-testing.

All our mobile survey forms and CAPI architectures are engineered offline-first. Mobile devices cache survey logic, media, and records locally without requiring internet connection until final upload.

Yes. Organizations frequently commission DataTech solely for XLSForm scripting, server setup, quality assurance monitoring systems, or statistical syntax processing while running their own field teams.

Yes. We author modular .sps (SPSS) and .do (Stata) syntax files that automate variable recoding, value labeling, multiple-response set restructuring, and sampling weight calculations.

Yes. We customize institutional Training of Trainers (ToT) and XLSForm masterclasses based on your team's specific questionnaire instruments, field protocols, and statistical objectives.

Yes. All survey instruments are engineered with standard Myanmar Unicode compliance, bilingual English/Myanmar labels, and customized font rendering for mobile devices.

Yes. We provide pre-deployment form audits, stress-testing cascading choice filters, constraint formulas, calculate statements, and server settings to prevent errors prior to data collection.
