Incorporation of HCI: Classification of activity modeling

In developing an interactive system, the design part corresponding to the specification of the functionality is commonly directed by the requirements. The specifications of these requirements are based on templates that classify activity in a way that in most cases, developers are not conscious and therefore do not understand how wrong classification because of methodological weaknesses, affects the understanding that has the user in relation with the system he is using. An ideal situation is that the developer fully understands what is the impact of wrong classification and help him to recognize the limits to define a scope for usability, safety or any other aspect. Our proposal is to define a classification model of the activity and make explicit the need for it to serve as a framework to promote software quality mainly it has to do with the Human Computer Interaction (HCI).
