About the checklist

The checklist was developed with the assistance of experts from various fields (e.g., psychology, social sciences, computer science) in a three-round Delphi study. Want to learn more about them? Have a look at the experts section. Although we refer to "the checklist", there are actually 331 different versions available. Just answer two simple questions, and you'll receive a tailor-made checklist for your project.
