This work proposes a set of complementary practices to agile methodologies, aiming at adapting them to the development of critical aerospace embedded systems by distributed teams. To identify the main gaps in this context, two approaches are used. The first one confronts the main activities required by aerospace standards for the development of critical embedded systems with a set of compiled agile practices derived from a review of the most common agile methodologies. The second one confronts the same set of compiled agile practices with the main problems of distributed development. The two approaches resulted in the identification of four gaps related to software integration, software traceability, communication management, and organizational differences. One complementary practice is then proposed for each gap. Two case studies were performed to assess the gaps and evaluate the proposed practices. Both emulate the development of critical embedded systems by distributed teams using agile methodologies. The case studies were performed with and without the use of the complementary practices. The results confirmed three of the four identified gaps and pointed to a clear contribution of the complementary practices.

这项工作提出了一套敏捷方法的补充实践，旨在使它们适应分布式团队开发关键航空嵌入式系统的需求。为了确定这种情况下的主要差距，使用了两种方法。第一个挑战是航空航天标准开发关键嵌入式系统所需的主要活动，其主要方法是对最常见的敏捷方法进行回顾而得出的一系列已汇编的敏捷实践。第二个面向分布式开发的主要问题，是针对同一组经过编译的敏捷实践。这两种方法确定了与软件集成，软件可追溯性，通信管理和组织差异有关的四个差距。然后针对每个差距提出了一种补充做法。进行了两个案例研究，以评估差距并评估建议的做法。两者都模拟了分布式团队使用敏捷方法开发关键嵌入式系统的过程。案例研究是在使用和不使用补充实践的情况下进行的。结果证实了四个已确定的差距中的三个，并指出补充做法的明显贡献。
