ABSTRACT Multimedia Interactive Informative Systems (MIIS) are software applications resulting from the convergence of multi- ples technologies such as audiovisual, computing and communication. They aim to transmit information to a large, di- verse and dispersed public. As with other mass media, the fulfillment of MIIS goals depends largely on the quality of communication between the system and end users. Therefore, those systems should be developed in order to ensure that this quality requirement is satisfied. If MIIS are constructed according to usual software engineering practices, the ana- lysis discipline of the development process includes requirements identification and specification; however, these tech- niques are focused on functional requirements, and they do not give much importance to non-functional requirements. In this paper, we propose a development process based on the production of videogames which has two different phases: preproduction and production. The first phase, corresponding to requirements identification, derives into the concept of system. In order to translate this concept into a specification, we propose the use of new communicational attributes and a MIIS metamodel. The establishment of MIIS non-functional specification is the result of analyzing class diagrams through quality attributes. In order to evaluate if the specifications are responding to communicational attributes, a functional prototype is built and evaluated with end users. The proposed methodology is applied to a real case study. Keywords: Multimedia Interactive Informative Systems; Multimedia; Quality Model in Use; Quality Requirements; Metamodeling 1. Introduction Multimedia Interactive Informative Systems (MIIS) are software systems that result from the convergence of multiple technologies, for example the combination of computational, audiovisual and communication techno- logies. The purpose of MIIS is to diffuse information to a large, dispersed, diverse, and non-captive public. An ex- ample of a MIIS would be a website whose goal is to transmit information, such as an online newspaper or a cultural website. A kiosk in a museum, cultural CD- ROMS, and many applications for mobile phones and tablets can also be considered as MIIS. As with other communication media, such as cinema and television, whether or not the MIIS fulfill its goals depends largely on quality characteristics related to the communication between the transmitter and the receiver. In this case, the qualities of communication between the MIIS and its final users are essential, and the success of the MIIS depends on the user finding these systems at- tractive, interesting, informative, and credible. However, these quality requirements are not included among the attributes of quality models used for software such as the ISO/IEC norm 25010 [1] and its predecessor ISO/IEC 9126. These types of non-functional requirements are diffi- cult to translate into specifications. But if they are not satisfied, the user can discard the application with the same freedom that she or he can change the channel of the television or leave a cinema when the film is disap- pointing, rendering the system essentially useless. Existing models of quality barely consider these char- acteristics. Software applications traditionally help cap- tive users to solve concrete problems, and there is no need for retaining their interest. The MIIS’s user, on the Copyright © 2013 SciRes. JSEA
