The methods and process of an objective product evaluation often include the measurement of user experience and user usability. This valuable information can be used to make a product or service modification before the final release to the market. Not to mention the cost that can be saved. Sometimes when picking up the right time and right customer groups, it might have a marketing effect through word-of-mouth advertising, from possible early adopters. They may create a special connection and feel loyal (feel of ownership through customer co-creation) because they were invited to share their opinion in the early phase.
