Notes on Compatibility with version 5.21

With version 5.21, we are making a big change by replacing census and sample mode with assignments. Previously when importing a questionnaire, users had to decide between sample mode (with a quantity of 1 interview per case) and census mode (with an unlimited quantity of interviews). With version 5.21, users will simply import the questionnaire and then proceed to making assignments with the imported template. Assignments will give headquarters users more flexibility because they can now specify the quantity of interviews they want when they generate each assignment.

How secure is the World Bank Cloud?

The World Bank Cloud is doubly secure. First, by relying on Amazon AWS, it provides best-in-class protections for even the most security-sensitive organizations and their data. External certifying bodies and independent security auditors have awarded Amazon AWS the long list of security accreditations listed below. Please visit AWS compliance resource page for more information. Second, on top of Amazon AWS’ security protocols, the World Bank provides an additional layer of protection through its own additional security measures.

Comparing floating point numbers and precision problems

Our support service often receives reports on suspected bugs in Survey Solutions on the grounds of a situation similar to the one described below. These reports stem from misunderstanding of some fundamental concepts of how computations are done by a computer, and not due to an actual defect of the software. Problem description Suppose you have a questionnaire containing two numeric questions X and Y, and a third question Z with an enabling condition (X*Y) == 21.

Deleting a survey

Survey deletion is possible, but as a dangerous operation is made available only to server administrators. When a survey is deleted all data collected as part of that survey is irretrievably and irreversibly lost. Hence the same steps should be applied as described in actions after the end of the survey. Make sure you backup your data before deleting a survey! Even if this was training, pre-test, or a field test.

Actions after the end of the survey

When the server is shut down all its data is removed permanently and irreversibly. Hence, at the end of your survey you need to secure the collected data. Instruct the interviewers to stop conducting interviews, mark them as completed. Synchronize all the interviews data from the tablets to the server. Do the final approvals/rejections of the submitted interviews. In HQ proceed to the data export screen. Download ALL data in all formats (tab-delimited and Stata and SPSS).

Actions during the survey

As a designated server administrator you will perform a number of key activities during the survey field work: Monitor the functioning of the server. Collect and analyze user problem reports. Attempt to address them to the extent possible. Refer the users to the corresponding sections of the manuals. Elevate the problems requiring developers’ attention to support. Preserve the copies of the uploaded sample files and split-key files. Periodically download, back up, and securely store the export data.

Actions before the survey starts

Upon a successful request of the server you will receive an email with the server address and administrator credentials. Immediately as you receive this information do the following: Go (in the browser) to the server and log in with the credentials you’ve received. Change the password if so desired. Record your new password and store securely with your records. Confirm to us per email that you could log in to the server and ready for work.

What to do in case a tablet gets broken, damaged, or destroyed.

The tablets used for data collection may get damaged or broken during the field work. If this happens: interviewer should immediately report this to his/her supervisor; supervisor should inspect the tablet and confirm the damage (often interviewers report tablets as broken when the tablets completely discharge and require long-press for power button to power up); supervisor should record the loss of a tablet and issue a replacement (possibly taking notes on the specifics of the devices lost and issued: model, serial number, date, interviewer name and login, circumstances of the loss, etc).
