Given the relevance that is taking the usability evaluation of software systems and especially web-based systems, the present work seeks to provide new evidence in the results obtained by applying combined techniques in usability evaluations. In this work, the process to schedule shipments using a web application was evaluated. First, a heuristic evaluation was performed and then a usability test with user. However, for this specific purpose, both tests will be applied independently to evaluate the results obtained. The evaluations were developed in an academic context.
