Web Interviewer CATI

Use in call-centres / CATI One specific scenario where the use of web interviewer is particularly handy is in conducting telephone surveys. In this case a call-centre is usually set up, with interviewers working from this office by reaching out the respondents by phone. The identifying fields of assignments are supposed to be pre-filled with the proper phone numbers that the interviewers will dial to get a response. This allows to avoid purchasing the tablets and to re-use the computer equipment available in the existing call-centre.

Web Interviewer Important Notes

To prevent collisions of multiple versions of the same interview, the interviewer is expected to utilize only one tool for each interview - either a tablet interviewer app or a web interviewer. An interview may be started with the web interviewer, and then continued on the tablet after the interviewer initializes and synchronizes it. In this case all the started interviews are marked as received by the tablet, and are still visible on the server (in web interviewer, as well as for the supervisor and HQ users).

Web Interviewer Dashboard

Consequences of relinking a tablet device

When an interviewer account is created at the HQ, an interviewer may connect from any tablet. Once the interviewer has signed in, that device ID is remembered and the interviewer must continue using the same tablet. No other interviewer will be permitted to use the same device: they will not be able to enter their username unless the interviewer app is uninstalled (with immediate loss of all unsynchronized data). It is not possible for one user to work on several devices.

Interviewer App Settings Dialog

Interviewers normally should not change any of the settings on this page, but may be required to do so based on the instructions of their supervisors or technical support. Some combinations or values of these settings may cause errors in operation/synchronization. Change these settings only if you know what you are doing. If you do make any changes compared to the default values, and you are requesting support from the development team, you must mention in your question, issue description, or the support request, which settings you've changed and which values you've specified.

Synchronization problems

Synchronization of the data between the tablet and server is a highly complex process of communication during which a number of actions are undertaken on both ends based on the flow of incoming data. Survey Solutions hides the complexity of it behind a simple Synchronize button available to the interviewer at any time. Normally, when synchronization is completed successfully, the interviewer receives a confirmation message and some summary statistics describing the actions taken (such as number of received assignments or transferred interviews).

Set up an Interviewer tablet by scanning a barcode

When an interviewer launches the Interviewer App for the first time she needs to provide the following three parameters: URL of the server (synchronization point), login of the interviewer (account name on that server), and the password of the interviewer. Typing in the server address may be time consuming and prone to errors, so to simplify the process Survey Solutions permits entering this information by scanning a barcode. This is especially useful for the ITs setting up a large number of tablets in the office for many interviewers at the start of the survey.

Multiple interviewers using the same tablet

Survey Solutions uses device tracking mechanism where for each interviewer account there is an indication of the currently linked device. In short this means that at any moment any interviewer may be utilizing only one device for data collection. Re-linking of the devices is possible, but it has some important consequences (explained here). At the same time it is still possible for multiple interviewers to use the same tablet for data collection, but every interviewer must have a different user account in the Android operating system to permit this.
