To make sure your participation provides value, evaluate its impact relative to your goals. Where did you succeed? How many of your planned goals did you achieve at the Democracy Festival? Did you create awareness of your research, establish new collaborations or communicate your research to society?
If the answer to the above questions is yes, then it is a good idea to reflect on how you reap the benefits what you sowed at the festival. Reach out to your new network and get appointments in your calendar with new potential partners.
If you didn't achieve your goals, is it an obvious opportunity to reflect on 'what went wrong'?
You can prepare as much as possible, but reality is sometimes different. Try to figure out what you could have done better: Could you have engaged in more outreach to participants (introducing yourself and presenting your research to strangers)? Could you have asked more questions at debates? You could discuss it with colleagues who also took part in the festival.
When you know what you can do better next year, you're even more likely to have a successful experience.
A systematic evaluation helps you strengthen your efforts next year and document the value of your participation for yourself, your colleagues and decision-makers.
