In a manufacturing process the focus is on delivering product characteristics by measuring and showing process control of product characteristics. Naturally the focus on manufacturing is laying on the primary refining steps, e.g. milling, drilling, grinding and welding, where hundreds of product characteristics are measured on every low volume component.
However a manufacturing process contains also secondary processes, i.e. supporting processes that are not producing product characteristics, but are necessary to perform in order to show fulfillment and to accomplish product characteristics in later process steps. In this presentation it is shown how important it is to measure process yield also in secondary processes.
An example will be given by starting with a process problem, and how process yield measurements have been implemented, and how the fact based common language have triggered and involved personnel on all levels (managers, process method engineers and operators) in continuous improvement activities of the process.
This work is an outcome of a structured six sigma work related to a cleaning process on a low volume aerospace components.
