Welcome to Sideband. A changing plan can feel like lost work. Before you start again, separate the purpose from the method. The purpose might be to help a customer understand a choice. The method might be a long guide, a conversation, or a small interactive tool. If the method stops helping, changing it does not mean the purpose was wrong. Make three short lists. What do we know from real use? What are we still assuming? What can we keep? Look for evidence that changes a decision, rather than collecting opinions about every detail. Then choose one next step with a clear stopping point. A smaller test can protect the useful work you have already done. Changing course is easier when you can explain which new information led to the change.
