Applying Persona-and-Scenario Method to Service Development of Home Network System

Currently, some researches and developments about Home Network System (HNS) which provide more convenient, comfortable life with using various services on the network are in progress. However, there is no service provided which is beneficial and value-added for users, therefore this system has not become popular yet. In this paper, we introduced Persona-and-Scenario method to service development of the system. This method is representative to propose and implement the services because of it is from the viewpoint of the users, not from the viewpoint of the developers. We also implemented“ Today ’s recipe service”, which is one of the services extracted by the method. We then took an evaluative experiment by usability testing with some actual users. As a result of the experiment, we found that the assessment of the services we developed was the highest by age 40 ’s mothers who are closest to the main persona we created. We confirmed the utility to apply Persona-and-Scenario method onto services development of the HNS from this result.
