Data Collection Tools

Data collection tools are software platforms that capture structured information through digital forms on mobile devices or web browsers. These platforms support validation rules, conditional logic, GPS capture, media attachments, and offline operation. Field teams use them to conduct household surveys, needs assessments, programme monitoring, beneficiary registration, and research studies.

Tools assessed

Licence clarification: Survey Solutions source code is available on GitHub but uses the World Bank Community Licence, which restricts commercial redistribution and requires acknowledgement. This differs from OSI-approved open source licences.

Form design and logic

Assessment notes:

• DHIS2 F1.1: Optimised for health data; lacks ranking, rating scales

Data capture

Assessment notes:

• LimeSurvey F2.1: Web surveys only; no native offline mobile application
• LimeSurvey F2.2, F2.6: Plugin-dependent functionality
• DHIS2 F2.7: Signature capture unavailable in Capture app

Data management

Assessment notes:

• CommCare F3.2: Bulk case editing requires Advanced plan ($500/month)
• CommCare F3.5: Report builder requires Pro plan ($250/month)
• LimeSurvey F3.7: Survey-focused; not designed for longitudinal tracking

Technical architecture

Assessment notes:

• CommCare T1.1: Self-hosting via CommCare Cloud requires substantial expertise; not standard deployment
• CommCare T1.6, T1.7: API access requires Pro plan ($250/month)
• Fulcrum T1.6: API access requires add-on or Enterprise subscription

Infrastructure cost estimates

Small deployment: 10 enumerators, 1,000 submissions/month

Medium deployment: 100 enumerators, 10,000 submissions/month

API specifications

API coverage by function

Encryption specifications

End-to-end encryption mechanism: ODK, Survey Solutions, and SurveyCTO support asymmetric encryption where submissions encrypt with a public key embedded in the form. Decryption requires the corresponding private key, held only by the organisation. Server operators cannot read encrypted submissions.

SSO protocol support
