3. Mobile data collection
Using smartphones
or tablets
for data collection
(instead of paper forms)

4. Data storage
build collect aggregate results
analyse - report

5. Advantages
 Manage surveys across regions;
 Faster to fill + compile;
 Data more accurate:
● collect+digitize at source
● no more data entry
● data cleaning limited
● pre coded ranges,
restrictions, skip logic
 user friendly / motivating;
 easy monitoring of data
collection team

6. Costs
 Hardware
 Training
 Collection form design
 Data transmission (recurring)
 Data aggregation (hosting)
 Management

7. Data types - what to collect
Geographic data
 GPS coordinates
Multimedia data
 Videos
 Audio
 Pictures
Choice boxes
 Radio buttons
 Multiple choice
Time - date
 Time
 Date
Sensors
 Signatures
 Barcodes
 Electronic sensors
Manual entry
 Text
 Numbers

8. Think ......
How could mobile data collection
be useful in your work?

9. Possible use cases
 Surveys
 Assessments
 Tracking
 M&E
 etc.

10. In CDI
 ISSD – with KIT Genevieve
 Cascape ?
 SBN ?
 IFAD evaluation

11. Many possible tools
 Magpi (episurveyor)
 Formhub
 Mobenzi researcher
 Commcare
 m-farm
 Do forms
 AKVO flow
 Text to change
 CSPro
 mOpenMRS
 Epicollect
 FrontlineSMS
 RapidSMS
 Ushahidi
 ODK – Open Data Kit

12. Considerations in selecting tool - provider
 Survey question types
 Control + management
(self or pay service provider)
 Data security
 Time-frame
 Costs (set-up / service)
 Customizability (by whom)
 Tools already used (partner)

13. Things to keep in mind before deployment
 How ‘fast’ do you need the data? Real time, daily, ...
 Network availability / affordability
 Materials
● Smartphone – tablet?
● Screensize?
● Operating System (Android, iOS, windows mobile)
● Extra spare devices
● Settings + installing device
● Battery pack

14. Planning
1. Ongoing activities
2. One-time activity

15. Yaw Anokwa http://nafundi.com
ODK - open data kit version 1.x
 Open Source + free, used by many (10s of thousands)
 Basis for many other apps (Enketo, Magpi, Kobo toolbox)

20. Pitfalls - risks
 Data security
 Broken devices / power
 Training enumerators – teamleaders
