Keep the task connected to the intended event
Begin with one event and the people who may update its tasks. Decide what a participant needs to see on a phone before making a change: the event reference, task description, current state and any relevant ownership. Keep the route back to the broader plan clear. Agree which actions belong to participants and which remain with the organizer. Review a person involved in several events so a concise mobile screen still provides enough context to avoid editing the wrong plan.
