A bottleneck is a process step, work cell, or equipment group whose available capacity is lower than the demand placed on it, thereby limiting the overall production rate of a line or plant. Value stream maps, capacity models, production schedules, and improvement reports use the term to flag where work accumulates and to guide decisions on overtime, buffers, or process changes.
In translation and localization, bottleneck appears in lean manufacturing training, plant performance reports, production planning software, and continuous improvement documentation. Translators may encounter phrases like 'bottleneck station,' 'bottleneck operation,' or 'shift the bottleneck.' The term requires consistent rendering across value stream maps and daily management boards so that production teams can compare findings across languages.
A frequent error is translating bottleneck as a literal physical constriction, such as a pipe neck, instead of the limiting process step. Another issue is rendering it as 'capacity problem' or 'delay' without preserving the idea that it sets the pace for downstream output. That weakens root cause discussions and can lead improvement teams to target the wrong operation.
The EU Machinery Directive requires documentation in the language of the destination market. Safety-related terms must map exactly to the wording of the governing standard.
Angel Translation locks terms like this into a project terminology base before expert review begins, so the same source term resolves to the same target term across every document in a submission — and stays consistent in the next revision. See the 8-step AI + expert workflow.
