There are different ways that exists to collect feedback:In order to have useful and relevant data, you should evaluate your event at the end of your activity, using tools such as with a wheel of emotion . Participants should be encouraged to provide feedback on what they found valuable, areas for improvement, and elements they enjoyed. This direct feedback can help to judge the success (or not) of the project. . A follow-up evaluation post-activity, preferably via email, can allow for a deeper understanding and feedback (at least one week after, and you can see in the Guide of Good practice for examples of tools you could use)
