Moment of truth refers to instances where a customer interacts with a business and forms an impression. There are four types of moments of truth: zero moment of truth where customers collect information; first moment of truth during purchase decisions; second moment when customers experience the product; and third moment when customers share feedback. Moments of truth provide opportunities for businesses to understand customer experience and resolve issues in order to improve impressions at each touchpoint along the customer journey. They differ from strategic occasions which marketers use to understand cultural contexts and consumer demand.
