Software development for military organizations follows standards and a set of guidelines established in the requirements engineering domain. However, these procedures are not always documented and it is difficult to reach understanding among stakeholders with varied backgrounds and interests. This article aims to obtain lessons learned through a case study of the development of a defense system for the Armed Forces of Brazil. From the validation of requirements specialist, a software development lifecycle was obtained that integrates the waterfall model and ISO/IEC/IEEE 29148 recommendations. The use of the model obtained facilitated the understanding of the processes that involved military teams, detailed specification of system requirements and success in the geoinformation based prototype.

将瀑布模型与ISO / IEC / IEEE 29148：2018集成以开发军事防御系统

军事组织的软件开发遵循标准和在需求工程领域中建立的一组准则。但是，这些程序并不总是记录在案的，并且很难在背景和兴趣各不相同的利益相关者之间达成共识。本文旨在通过对巴西武装部队防御系统的发展进行案例研究来吸取经验教训。通过需求专家的验证，获得了一个软件开发生命周期，其中集成了瀑布模型和ISO / IEC / IEEE 29148建议。使用所获得的模型有助于理解涉及军事团队的过程，详细的系统要求规范以及基于地理信息的原型的成功。
