Sequenzplan

Sequenzplan is a planning document that organizes activities or operations in a predefined order to improve efficiency and safety. The term is mainly used in German-speaking contexts; English sources usually render it as "sequence plan." It often forms part of broader planning frameworks, aligning tasks, resources, and timelines to a chosen sequence.

A sequenzplan typically lists steps in their required order and includes elements such as step description, duration, prerequisites, responsible party, required resources, and constraints related to safety, quality, or environment. Many implementations use dependency indicators and connect the sequence to a schedule or calendar. Visualizations like flow charts or sequence diagrams are common.

Applications span several domains. In manufacturing and assembly, the sequenzplan specifies the order of operations to minimize setup time and avoid bottlenecks. In laboratories, it structures experiments and sample handling. In construction and logistics, it sequences phases and activities. In film and media production, it may outline scene or take order. In software and IT, it can document execution order for critical processes.

Creation and maintenance: sequenzplans are typically developed by process engineers, project managers, or team leaders during planning and updated as data changes. Benefits include clearer coordination, reduced idle time, and easier bottleneck identification; limitations include dependence on accurate data and the potential for complexity with many interdependencies.

Related concepts include process maps, Gantt charts, workflows, and method sheets, which provide complementary views of sequencing, scheduling, and resources.
