Survey Description

Do you have experience with a programming language and an Integrated Development Environment (IDE) like Eclipse, IntelliJ IDEA, NetBeans, or Visual Studio? If so, we would appreciate your feedback. Your responses to the following questions will be used for a research project that aims to augment IDEs like Eclipse with new, interactive ways to help professional developers transform their code.

This survey will take about 20 minutes and all responses will be completely anonymous. At the end of the survey, you will have the option to submit your e-mail address to be notified when our tool is available for further user testing. If you choose to provide us with your e-mail address, you will be presented with a separate form to ensure that your survey responses will not be linked to your e-mail address.


We will store the results of this survey in secure storage spaces. We may share the results of this study with others in our scholarly articles. We will ensure that the shared data does not include any information that makes it possible to identify you.
