Which term refers to an announcement system used to indicate the need for reactive maintenance?

The term that refers to an announcement system used to indicate the need for reactive maintenance is Andon. In a manufacturing environment, Andon is a visual management tool that provides real-time information about the status of the production process, including any issues that may require immediate attention or maintenance. It allows operators and managers to quickly identify problems, facilitating a prompt response to minimize downtime and disruptions in production.

The effective use of an Andon system enhances communication on the shop floor, ensuring that any maintenance needs are communicated clearly and addressed swiftly, ultimately contributing to overall efficiency and productivity in manufacturing operations. It is particularly crucial for environments that aim for lean manufacturing practices, as it promotes responsiveness to issues as they arise.

The other terms, such as KPI (Key Performance Indicator), Kanban, and Scrum, do not directly relate to maintenance announcement systems. KPI focuses on measuring performance metrics, Kanban involves inventory and work-flow management techniques, and Scrum is an agile project management methodology primarily used in software development and project management, rather than in reactive maintenance contexts.
