System Usability Scale Analysis Toolkit

The System Usability Scale (SUS) Analysis Toolkit is a web-based python application that provides a compilation of useful insights and contextualisation approaches based on findings from the scientific literature for the System Usability Scale questionnaire that was originally developed by John Brooke. It allows researchers and practisionaires to calculate comparative, iterative and singular SUS usability study datasets. Furthermore, it provides utility to contextualize the meaning of calculated scores, compare them against scores gathered in meta-analyses, calculate SUS scores conclusiveness and analysing the contribution of specific questions of the 10-item questionnaire to the SUS study scores.

An online version of the SUS Analysis Toolkit is hosted at:

Quickstart – Running the SUS Analysis Toolkit locally

  1. Install Python 3.9. On Windows, make sure to check “Add Pythong 3.9 to PATH” during installation
  2. Clone this repository, or manually download it as a zip file and extract it
  3. Open the sus-analysis-toolkit folder
  4. Open the terminal (E.g. Windows Terminal) in the sus-analysis-toolkit folder
  5. Run the following commands to automatically install all dependencies:
python -m pip install --upgrade pip setuptools
python -m pip install -r requirements.txt
  1. Alternatively, install the requirements manually by installing all packages specified in the requirements.txt:

  1. After successful installation, run the toolkit locally with the command:

Running the SUS Analysis Toolkit on a server

To run the SUS Analysis Toolkit on a server, we recommend building a Docker Image and hosting it in a Docker Container. The required Dockerfile is included in this repository.

Contributing to this project

As the SUS Analysis Toolkit is an ongoing project, we are happy to receive feedback, suggestions and bug reports through Email or GitHub Issues. Additionally, we are planning to develop the tool further towards including more statistical data analysis tools, automated API processing and improving its accessibility and usability. Therefore, we are happy to collaborate with developers and experts in these areas.
