Messplan

Messplan is a document used in German-speaking contexts to outline planned measurements for a project, experiment, or regulatory program. The term is commonly translated as measurement plan or data collection plan in English. The purpose is to ensure data quality, traceability, and alignment with objectives.

A Messplan specifies what will be measured, how it will be measured, with which instruments, where and when sampling will occur, how data will be processed and stored, and who is responsible. It typically covers objectives and scope, variables and endpoints, measurement methods and instrumentation, sampling strategy and frequency, data quality objectives and acceptance criteria, calibration and maintenance, data management and documentation, and roles, responsibilities, and change control.

Applications include scientific research, environmental monitoring, manufacturing quality control, clinical trials, and civil engineering projects, among others. The plan is created during project planning and trial design and is revised as needed, with formal approvals and version control.

Messplan is related to but distinct from a complete experimental protocol, statistical analysis plan, or quality plan. In English contexts, its equivalents include measurement plan or data collection plan.
