New version of Questionnaire Designer; the Headquarters console supports bulk uploading of interview assignments
Substantial changes have been introduced to the Questionnaire Designer:
- The application makes a more efficient use of the screen size, while new tool tips provide contextual help to the users;
- The SingleOption and MultiOption questions are now called “Categorical: one answer” and “Categorical: multiple answers”;
- Adding a new option to a categorical question is much easier—it can now be done with one click and does not require any further confirmation;
- The “Export to PDF” function has been redesigned. The PDF files generated by the system now feature a cover page, distinguish between different types of questions and include the condition and validation expressions
Additionally, we have introduced the possibility of importing large batches of addresses to be visited by the interviewers from a CSV file.
New interface and further performance improvements
A new, responsive user interface has been introduced to the Headquarters and Supervisor consoles, making it easier to quickly add new supervisors and interviewers and match them to single or multiple households (or other interview assignments). We have also rolled out further performance improvements: downloading 1000 questionnaires to a tablet device takes only 8 minutes; uploading 1000 completed questionnaires to a cloud server takes 30 minutes. The supervisor console can handle over 10,000 submissions and generate statistics without noticeable delays.
Synchronization of the data between tablet devices and the server is now faster; thousands of completed questionnaires can be uploaded within minutes. The system handles broken internet connections more robustly and without data loss. The tablet application displays a gauge measuring the synchronization process.
Questionnaire Designer users can now make their questionnaires public (available to other users).
The CAPI project started in early 2012 in cooperation with the Bill & Melinda Gates Foundation, the Living Standards Measurement Study-Integrated Surveys on Agriculture team and the Food and Agriculture Organization of the United Nations. Initially, the client software was produced for Microsoft Windows 7-based Tablet PCs; at the same time first versions of the Survey Management System (the server software) have been released.
The project, however, coincided with massive changes to Microsoft Windows-powered tablet devices. Windows RT, the successor of the tablet version of Windows 7 that was launched in September 2012, has not preserved backward software compatibility. Consequently, applications written specifically for Windows 7, such as the CAPI client, would not work on the newer devices.
At the same time, the market share of basic Android tablet devices kept growing, especially among low-cost devices that could be purchased also by austere governments or from shoestring research budget. As a result, our team decided to concentrate its efforts on developing an Android-based client, with the possibility of extending the support to other platforms at a later stage.
The change in the chosen platform led to postponing the implementation of certain features, as the attention of the developers was focused on producing the new version of the client. Given that, the first pilot survey using the CAPI system was started only in March 2013 in St. Lucia.
