Uma das etapas da Avalia??o Cooperativa ? a elabora??o de uma lista de tarefas que o usu?rio deve realizar para avaliar a interface. Fez-se necess?rio, ent?o, definir as tarefas que deveriam compor a avalia??o de usabilidade. Procuramos, sem ?xito, um processo de compra em aplicaivos para smartphones a fim de definir quais tarefas deveriam ser testadas pelos usu?rios. Encontramos, em literatura, somente processos de compra para sites. Com a participa??o de usu?rios adaptamos, ent?o, um dos processos de compra para sites ao contexto do site da Livraria Saraiva, objeto eleito para viabilizar o nosso estudo. Com este novo processo de compra para o contexto do site da Livraria Saraiva, verificamos se as etapas de compra eram correspondentes ?quelas referentes ao aplicativo m?vel para smartphones da mesma livraria. Verificadas as discrep?ncias, finalmente propusemos, junto com usu?rios, um processo de compra m?vel em aplicativos para smartphones no ambiente da Livraria Saraiva. A partir deste diagrama, fizemos uma Avalia??o Cooperativa no aplicativo de m-commerce da referida livraria. Este trabalho resultou na elabora??o, com a participa??o dos usu?rios, de um processo de compra considerando as etapas de compra que refletissem a forma de comprar dos usu?rios, quando est?o diantes da interface de aplicativos m?veis de m-commerce desenvolvidas para smartphones, o que orientou a avalia??o da usabilidade na interface do aplicativo m?vel de m-commerce da Livraria Saraiva e, poder? servir a outros estudos, tanto como base metodol?gica quanto como diagrama de aplica??o em interfaces an?logas. Ainda, os resultados nos fizeram concluir que incluir os usu?rios na avalia??o de interfaces deve, se poss?vel, tamb?m pressupor a inclus?o dos mesmos no ajuste dos par?metros dos instrumentos que ser?o usados na avalia??o. ABSTRACT: We were motivated to do this work because we have found in literature about m?commerce most users revealed reluctance to buy via mobile applications in smartphones. At first we meant to use the technique of cooperative evaluation with users to investigate the usability of these shopping environments in mobile applications to smartphones. One of the steps of cooperative evaluation is the preparation of a tasks list which the user must do to evaluate the interface. It was necessary, then, to define the tasks which should compose the usability evaluation. A purchasing process in applications for smartphones was seeked, unsuccessfully, in order to define which tasks should be tested by the users. In the wide information source we only found site?s process of purchase. We made some changes for sites in the purchasing context of the site of Saraiva Bookstore with the participation of users, then, the elected object to enable this study. With this new diagram for the context of Saraiva Bookstore's site, it was checked if the steps were corresponding in the mobile application for smartphones of the same bookstore. The discrepancies were verified and it was proposed, with the users, a diagram for the purchasing process in applications for smartphones in Saraiva bookstore's shopping environment. Based on this diagram we have defined which tasks should be tested by users and the cooperative evaluation was made in the application of m-commerce of this bookstore. This work led to the development, with the users, of a diagram with purchasing steps and these steps reflected the way users purchase when they were faced to m-commerce mobile applications developed for smartphones. The purchase process diagram guided the cooperative evaluation with the application of m?commerce studied and helped us to conclude that including users in the evaluation of interfaces should, if possible, also mean to include them in the construction of their own instruments. This led to the develop steps of purchasing process, with the participation of the users considering buying which reflected the way users buy when they have to use m?commerce applications developed for smartphones mobile interface and this guided the evaluation of the usability of mobile application m-commerce Saraiva interface. This study may be applied to other studies, both as a methodological basis and as well as a diagram analogous application interfaces. Still, the results have made us conclude including users in the evaluation of interfaces should, if possible, also assume their inclusion in adjusting the parameters of the instruments which will be used in the evaluation of the interface.
