Oppsetttid

Oppsetttid is a term used in some Norwegian-language contexts to denote the time required to prepare a system for a new task or production run. In standard usage, the concept is more commonly described as oppsett tid (setup time) or oppsettstid. The triple-t spelling, oppsetttid, appears as a variant in online texts and informal writing, but it is not widely established in formal terminology. The core idea is the same: it is the period of preparation before productive work can begin.

In practice, oppsetttid encompasses activities such as changing tools, adjusting settings, loading materials, programming, aligning equipment, and performing safety checks. It is a component of cycle time and can significantly influence throughput, lead times, and inventory levels. The concept is used across industries, including manufacturing, document processing, software deployment, and data-center operations, where there is a need to prepare systems or processes for a new task or configuration.

Measurement of oppsetttid typically starts when the previous operation ends and ends when the system begins producing acceptable output. For example, a machine that switches from one product to another may incur a 10–15 minute oppsetttid, with portions that are non-value-added. Reducing oppsetttid is a common objective in lean and operations management, enabling faster changeovers and shorter lead times.

Reduction strategies focus on separating internal and external setup tasks, standardizing tooling and fixtures, pre-staging components, cross-training operators, and applying parallel work or automation. These approaches align with principles such as SMED (Single-Minute Exchange of Die) to minimize setup time and improve overall process efficiency.
