Discussion forums are used to find unmet needs in a product or service. To prepare for this experiment, you need to identify which forums you want to use and define the questions you want to answer, such as whether you are solving top customer jobs, addressing major customer pains, or creating customer gains.   To execute the experiment, you search for phrases related to your questions on discussion forums, take screenshots, export your results, and write down notes about the sense of urgency and tone in the forum threads.   To analyze the results, you update your Value Proposition Canvas based on your findings, contact the forum posters in direct messages to learn if they will speak to you in more detail, and if so, run experiments with them to help close the gap.
