In recent years, space projects have evolved to faster and more variable projects. To adjust the design processes in accordance, new work methodologies arise, as the Concurrent Engineering (CE). This working discipline is characterized by collaborative design and the flux of information being improved by working in a dedicated environment. CE has been recently adopted by space industry for the preliminary design phase of spacecrafts and other space systems. However, this methodology does not envisage tasks prioritization, which is a fundamental aspect to achieve an optimal design solution with an efficient allocation of resources. In this work a variation of CE discipline by applying Agile methodologies (in which the aspect of task prioritization is essential), is proposed. Agile methodologies allow the proper distribution of the design effort depending on the project priorities, the state of the design and the requirements, in a continuous process to improve the design solution. The general aspects of the proposed method are presented and applied to the design of a space mission, the results being analysed and compared with to the classical CE process in order to outline its differences and similarities with CE and Agile methodologies and show its potential for a new environment for space project design.

近年来，太空项目已经发展成为更快、更多变的项目。为了相应地调整设计过程，出现了新的工作方法，如并行工程 (CE)。该工作学科的特点是协作设计和通过在专用环境中工作来改进信息流。CE 最近已被航天工业用于航天器和其他航天系统的初步设计阶段。然而，这种方法没有设想任务优先级，这是实现具有有效资源分配的最佳设计解决方案的基本方面。在这项工作中，提出了通过应用敏捷方法（其中任务优先级的方面至关重要）来改变 CE 学科。敏捷方法论允许根据项目优先级、设计状态和要求，在持续过程中适当分配设计工作，以改进设计解决方案。提出了所提出方法的一般方面并将其应用于太空任务的设计，分析结果并与经典的 CE 过程进行比较，以概述其与 CE 和敏捷方法的差异和相似之处，并展示其在空间项目设计的新环境。
