# Evaluation Evaluation is useful for two key reasons: 1. Improving your processes 2. Sharing learnings with others hosting similar events Evaluations are helpful both during and after your event. Evaluations at the end of each session are particularly helpful if you intend on hosting more than one session, or a follow-up conversation in the future. One way of doing an evaluation with folks on-site is by using the **Plus Delta practice**.
##### *Plus Delta practice* At the end of a session, distribute two sticky notes to each participant. One sticky note will be marked with a plus (+) sign, and the other with a delta (∆) sign. Ask them to answer the following question on each corresponding sticky note: - \+ What did you like? - ∆ What can be improved? |
