A Theory of Strategic Information Technology Unavailability
重新定义IT不可用性为IT资源需求未满足，通过分析28个真实事件，揭示三个反馈循环如何加剧服务中断、延迟恢复并放大下游影响，对IT管理者有实践指导意义。
This study develops a practice-relevant theory explaining why some information technology (IT) unavailability incidents lead to severe and prolonged organizational consequences. By redefining IT unavailability as unmet demand for IT resources rather than simple system downtime, the paper shows how disruptions cascade through information capacity deficits and business capacity deficits, ultimately impairing critical services, affecting clients, and damaging organizational reputation. An analysis of 28 real-world IT unavailability incidents reveals that three reinforcing feedback loops (IT inertia, information inertia, and business inertia) can intensify service disruption, delay recovery, and amplify downstream impacts.
