Description
Operating a large-scale scientific facility such as the European XFEL requires reliable and efficient on-call duty (OCD) management to support 24/7 operations. Initially, these processes relied on manual spreadsheet-based workflows, which were error-prone, non-scalable, and inefficient, consuming effort that should instead be dedicated to development and operational tasks, such as assessing staff availability and tracking working hours, including nights, weekends, and public holidays. To address these limitations, we developed the On-Call and Data Operations Center (DOC) Manager (OCDM), a web-based platform that supports on-call and shift scheduling, incident tracking, and the management of staff availability and personal constraints. The system is built on a layered Java architecture (MVC) following a client–server model. In continuous operation since 2018 and currently used daily by more than 120 active users, OCDM has, within an 18-month audited log window, recorded more than 16,000 access events, including more than 4,800 scheduling operations and 3,000 automated notification emails. This demonstrates the crucial role that OCDM has gained within the data department of the European XFEL.
