Abstract:
Due to their unique characteristics, military domains contain various peculiarities that directly or indirectly and favourably or unfavourably impact the development of software products. Observations of systems development in the Brazilian Navy for many years have shown that systems are developed and delivered usually with many delays, and during development there are many changes to the requirements initially elicited. Since many authors in the software engineering literature agree that problems in requirements account for more than 70% of total system development failures, it seemed to be logical that any effort to solve the problems encountered in the military environment should start focusing on the requirements area. Currently several techniques and approaches already exist that support the execution of activities in this phase. With this abundance of techniques, it becomes a difficult task for the analysts to select the best technique in a given circumstance. To support the selection of these techniques, several frameworks were also created, each one guided by a respective group of influencing factors. This study examined, in a detailed manner, these techniques and frameworks, and noticed that there are still issues to be addressed to guide the selection of elicitation techniques, especially in a complex environment such as the military one. To elicit these issues an exploratory qualitative research was performed. The results showed that social issues rather than technical ones were the main concern in the domain under study. Issues such as hierarchy and high staff turnover interfere in the requirements process but are yet not addressed. The findings of the qualitative research are the first contribution of the thesis. Based on these results this research proposed a novel framework for requirements elicitation within the context of a military environment taking into account social and technical factors, which is the second contribution of the thesis. Such a framework was developed following Conflict Theory from sociology. This framework organized a selection of techniques based on possible solutions to conflicts. Finally, the solution was evaluated to assess its efficacy. This evaluation was based on qualitative and quantitative research. Based on the evaluation results the framework was updated.
