Läpimenokertoja

Läpimenokertoja is a Finnish term that appears in discussions of process theory, manufacturing, and data processing. The word is formed from elements meaning to pass through, flow or movement, and times or occurrences. The term is used to denote the count of pass-through events in a defined stage or process, rather than a rate.

In practical use, läpimenokertoja describes how many times something passes through a specific operation or stage. It can refer to how many units move through a production step in a batch, how many times a data item travels through a pipeline stage, or how many times a signal is reprocessed due to rework. For example, a production line where some items require rework might have a higher läpimenokertoja than the nominal throughput, since passes through the operation are counted each time.

Because the term is not part of standard Finnish dictionaries, its meaning can vary by organization. It is most often found in internal production reports, quality assurance documentation, or data engineering notes rather than in formal vocabulary.

Related concepts include läpäisy, throughput, and processing iterations. See also throughput, cycle time, and rework rate. Given its informal status, users should define precisely what counts as a pass-through when using the term in reports or analyses.
