Manufacturing output increasingly depends on a resource no balance sheet captures: the operational knowledge held by experienced workers.
In the United States, more than 25% of the manufacturing workforce is aged 55 or older, according to data compiled by the U.S. Bureau of Labor Statistics — a cohort approaching retirement and taking decades of process expertise with them. Facilities have no reliable system to capture what those workers know.
The consequences are measurable. Research from the National Institute of Standards and Technology found that process variability in manufacturing directly increases defect rates and rework costs. New hires are onboarded against formal procedures that often omit the informal knowledge that actually drives performance.
The underlying problem is structural: expert knowledge lives in people, not systems. A survey of 1,000 organizations conducted by APQC found that 92% of organizations do not consistently capture knowledge from soon-to-be retirees — even as 58% of C-suite leaders describe the risk as a very serious concern.
