This research concerns the definition directly then relatively thin aesthetic appearance must have an innovative product in the market. Maya et al (2011) have shown that within the set of methods available to make that definition (Kansei engineering, laddering, ZMET, semantic differentials, Mood Boards, TMN Mills Trends, PDT) the PDTs are a method that can be adapted While Colombian industrial context. Indeed, no PDTs special statistical knowledge required for their realization or professionals (ie psychologists) nor expensive studies mass users, which can be used for the same product designers. However, since the method presents some of his instructions so unstructured, it is reasonable to think that by using this method enter designer subjectivity biases and errors in the preparation of the plates of trends that reduce accuracy. The research problem is then how to formalize this method instructions are still very formalized below are the different questions under unclear areas identified in the implementation and evaluation of TBM. By formalizing the rules of construction of the TBMs are looking to achieve PDTs that are more consistent and accurate in terms of the ux to propose to the user (ie the aesthetics of the product is the most appropriate to the user's expectations).
