Information System (IS) research has overlooked user conflicts in teams among simultaneous or successive Information Technology (IT) projects, leaving a gap in comprehending the potential contagion processes leading to project failure. While IS literature has separately developed theories on conflicts and conflict contagion, we conceptualize a whole theoretic system we call "IT Conflict Contagion" (IT-CC). This theory is used as a driver for a 2-year action research project conducted at a French management consulting firm during the second attempt of its Business Intelligence (BI) tool baptized “PMT.” While most MIS methods tend to manage conflicts within the boundaries of an IT project, we emphasize the need for a comprehensive understanding of past IT implementations and their impact on subsequent projects despite the different aims, designs, and functionalities of these IT systems. This research calls for IS researchers and practitioners to adopt a holistic conflict management perspective, considering the IT portfolio and the interplay between various IT systems to ensure successful IT implementation.

信息系统 (IS) 研究忽视了同时或连续的信息技术 (IT) 项目中团队中的用户冲突，从而在理解导致项目失败的潜在传染过程方面留下了空白。虽然 IS 文献分别发展了关于冲突和冲突蔓延的理论，但我们概念化了一个称为“IT 冲突蔓延”（IT-CC）的整个理论体系。该理论被用作法国一家管理咨询公司在其商业智能 (BI) 工具（称为“PMT”）的第二次尝试期间进行的为期 2 年的行动研究项目的驱动力。虽然大多数 MIS 方法倾向于管理 IT 项目范围内的冲突，但我们强调需要全面了解过去的 IT 实施及其对后续项目的影响，尽管这些 IT 系统的目标、设计和功能不同。这项研究要求信息系统研究人员和从业者采取整体冲突管理的视角，考虑IT组合和各种IT系统之间的相互作用，以确保成功的IT实施。
