What is the limit on the number of questions and respondents?

1KA's capacities and capabilities are in all respects sufficient for the current needs of all users on 1KA Arnes (all of whom have the 3KA package) and 1KA.si installations. In the case of a project with greater needs, they can be further adapted, which is associated with additional costs (e.g. private installation, cloud service, etc.). The current limitations are as follows:  

  • Number of surveys and responses collected: Depending on the selected package, the user can create a limited number of surveys and collect a limited number of responses, where only the responses with a status of 5 (partially completed questionnaire) and 6 (completed questionnaire) are counted:
    • 1KA: Free packages have an unlimited number of surveys available, up to 5000 respondents or collected responses per survey.
    • 2KA: unlimited number of surveys, up to 5000 respondents or collected survey responses.
    • 3KA: unlimited number of surveys, up to 5000 respondents or collected survey responses.
  • In the event of a survey exceeding these limits, the administrators reserve the right to deactivate the survey, in which case the author of the survey will be notified by email.
  • Number of questions: when creating and editing surveys with a large number of questions, 1KA takes into account the current capacity of the technology (PCs, mobile devices and internet connections), so the response time when editing the survey can improve quickly. In principle, there can be hundreds of questions, whih is very rare in a normal questionnaire but can easily happen in surveys with complex randomization blocks.
  • For optimal performance of the survey and data analysis within 1KA, we recommend up to 200 questions, after which you may gradually experience longer response times for editing the questionnaire, longer database generation times, problems with exporting the respondent's answers (the file is not exported as in such a case, the PDF of one respondent's answers may exceed 300 MB), problems with exporting data and analyses. If you need more questions, you can split the questionnaire into several surveys or arrange your own installation with a more powerful server.
  • Number of loops: a maximum of 10 loops can be inserted in one questionnaire.
  • Number of questions per loop: you can insert up to 10 questions per loop in the questionnaire
  • Number of invitations sent via the 1KA system: only 3KA users can send invitations via the 1KA e-mail interface. There are two options:
    • user's own SMTP server: If you are sending from your own SMTP settings, please note the limitations of your mail provider (e.g. in 2021, Gmail had a sending limit of 500 per day).
    • 1KA email server: It is possible to arrange to send invitations via the 1KA email server (e.g. research@1KA.si or raziskave@1KA.si or via your 1KA domain), where certain restrictions also apply. In this case, the user may send the invitations within the limites specified in their individual agreement.
  • In all cases, however, mass sending of e-mails to recipients who have not previously authorised it, or sending in contravention of applicable law, is expressly prohibited and is considered to be a gross violation of 1KA's General Terms and Conditions of Use.
  • Number of simultaneous administrative users: in regards to the number of concurrent administrative users developing their survey, 50 editors have been tested simultaneously so far without any impact on the speed of the application. We estimate that this number could be more than 100.
  • Number of simultaneous respondents: 200 respondents can complete the survey at the same time. In practice, this means that a maximum of 200 respondents can click on the survey at the same time in one second. When this number is exceeded, a message is displayed to the respondent indicating that the maximum number of simultaneous respondents has been reached and that they should try again in a few moments. This limitation is not a consequence of the 1KA tool, but rather a technical adjustment of the servers, as otherwise (e.g. a few thousand simultaneous respondents) there may be problems with the functioning of the server. As for most of the constraints, it can be eliminated or mitigated by additional agreement.
  • Exporting the responses of all valid respondents: Printing out the responses of all valid respondents involves a verbatim printout of the questionnaires and responses for each respondent in one document, which can be extremely voluminous. Therefore, it is only possible to extract all the responses of all respondents into one document (PDF or WORD) for 300 or fewer respondents. If there are more respondents, this output is disabled by default.
  • Data import: using the add data function, you can add new records to the survey, i.e. new respondents. There is no limit to the number of respondents you can add. However, there are restrictions on the types of data or variables that can be added. You can only add data that correspond to text and numeric type variables (text question type, number question type) and single and multiple choice questions. Other types cannot be entered at this time. Data for the other question types can be added manually (in the respondent's survey editing) at a later stage.
  • Using the merge data function does not increase the number of records in the survey, but adds data to existing respondents. The same restriction applies as when adding data. So, you can only add data that correspond to variables of text and numeric types (text question type, number question type) and single and multiple choice questions. Data for other question types can be added manually (in the respondent's survey editing) afterwards.
  • Data piping: when transferring a value from the answer to one question to the text of another question or answer, you can currently only transfer a value from questions of type category single-answer, category multiple-answer, text, number and table.
