Agile development became very popular at the beginning of the 21st century when the Manifesto for Agile Software Development was released. Since then, it has been predominant in the software industry and has been increasingly transferred to the development of physical products due to its great success. There are many studies on Agile-Stage-Gate hybrids that combine agile Scrum and the traditional Stage-Gate model, however no research has been found that addresses a direct integration of Scrum into a concurrent product development model in a similar way. In this paper, we therefore examine the possibility of introducing Scrum into the concurrent product development and propose a Scrum framework for an Agile-Concurrent hybrid. We propose that the framework for concurrent development remains unchanged: the stages overlap and the track-and-loop approach is preserved, while Scrum is proposed for the execution of day-to-day work. The main advantage of the proposed hybrid is that after each iteration the customer reviews the results of an entire loop, not just of one stage, which enables a broader understanding of the progress and facilitates a more extensive feedback. A quicker resolution of discrepancies, and a faster and more effective response to change is thus ensured. In the paper, the needed organizational changes and potential implementation issues are also discussed.

敏捷并发混合：使用 Scrum 进行并发产品开发的框架

敏捷开发在 21 世纪初发布敏捷软件开发宣言时变得非常流行。此后，它在软件行业占据主导地位，并因其巨大的成功而越来越多地转移到物理产品的开发中。有许多关于结合敏捷 Scrum 和传统 Stage-Gate 模型的 Agile-Stage-Gate 混合体的研究，但是还没有发现以类似方式将 Scrum 直接集成到并发产品开发模型中的研究。因此，在本文中，我们研究了将 Scrum 引入并发产品开发的可能性，并为敏捷-并发混合提出了一个 Scrum 框架。我们建议并发开发的框架保持不变：阶段重叠并保留了跟踪循环方法，而建议使用 Scrum 来执行日常工作。提议的混合的主要优点是，在每次迭代之后，客户审查整个循环的结果，而不仅仅是一个阶段的结果，这样可以更广泛地了解进度并促进更广泛的反馈。从而确保更快地解决差异，以及更快、更有效地响应变化。在本文中，还讨论了所需的组织变革和潜在的实施问题。这有助于更广泛地了解进展并促进更广泛的反馈。从而确保更快地解决差异，以及更快、更有效地响应变化。在本文中，还讨论了所需的组织变革和潜在的实施问题。这有助于更广泛地了解进展并促进更广泛的反馈。从而确保更快地解决差异，以及更快、更有效地响应变化。在本文中，还讨论了所需的组织变革和潜在的实施问题。
