Hot deck cold deck methods are widely used in official business settings, as they have been found to be effective at providing accurate results. But what exactly is hot deck cold deck and why is it so important? Hot deck cold deck refers to the technique of coding responses based on a “hot” answer that was either shared or close to being shared by two or more people, and “cold” answers that were not shared by anyone. This method can provide better insights into customer opinion than traditional open-ended questions because it reveals deep-seated beliefs and enables accurate tracking of opinion over time. By getting a consensus view from multiple customers, business owners and decision makers are able to understand their customers’ opinions and make more informed decisions.
