Although developing software artefacts, such as software
components or mobile applications, follows several standard
software process models depending the nature and the aims of
the artefact, however it is possible to generalise the inputs of all
these processes into idea and resources, and the output of the
software product [4]. Taking into account that, for answering
the proposed research questions and reaching the aim of the
study, it is desirable to develop an application using HumanComputer
Interaction (HCI) approach as the software
development process [5]; this means the idea and resources
will come from people as input process, and in order to follow
the Iterative design used in HCI, it is necessary to refine and
improve these inputs in each iteration process. However, In
order to discover what characteristics of the application change
people behaviour, it is necessary a method that helps to identify
cause-effect relationships related to the desired behaviour
