Abstract

In first-class restaurants, including fast food establishments, there is a certain level of dissatisfaction on the part of the client, although, a part is due to the product, another part is due to the quality of the service that is presented in these places and the Customer Support. Therefore, the present work presents a solution that consists of using a virtual assistant in conjunction with a screen that serves as visual support for order taking. These types of applications can improve customer satisfaction and also add value to the business through more information for its customers. The proposed solution uses two frontend applications using Angular as a framework, a backend developed using the NestJS framework and a voice application developed in Dialogflow in order to be able to use Google Home devices or Android-based devices for communication with the client. final. In this way, the menu, products, categories, subcategories, options and types of options that can be shown to the customer for their choice are managed. In addition, the SCRUM framework was produced for the development of the project in order to have a way of measuring and distributing the work based on the complexity of the elements to be developed. At the end of the development of the applications, usability was evaluated by using the SUS (System Usability Scale) survey, obtaining a value of 77.00 / 100 for the order taking application, that is, the set between the application of voice and the web application that works as a visual aid.
