Along with this analysis this paper presents the necessary parameters to put on data cost-benefit  that all the procedures describes intent to establish technical directions when such events occurs on the matter. It is applied a systematic negotiation for conflicts resolution adopting guidelines and international standards. To achieve satisfactory reliability, availability, maintainability and safety requested, these factors must be considered in early stage of the system development. With the increasing the system complexity, there is a growing necessity for knowledge on the application of concepts regarding the most suitable architecture, in order to reduce costs and increased quality. Then, this work aims to give a direction to the stakeholders regarding the choice of appropriate alternative structure considering the application domain by establishing a rational. This analysis is developed based on estimation methods and cost evaluation, using industry design standards and mathematical models to represent the analyzed systems and it is applied on the real case.Along with this analysis this paper presents the necessary parameters to put on data cost-benefit  that all the procedures describes intent to establish technical directions when such events occurs on the matter.
