Harpers Ferry Armory Case
Smith's paradigmatic demonstration (1820s–1850s) that identical technologies produce divergent outcomes in different institutional cultures—Springfield adopted, Harpers Ferry resisted precision manufacturing for a decade.
The Harpers Ferry Armory case is the empirical foundation of Merritt Roe Smith's institutional framework. Between the 1820s and 1850s, two federal armories—Springfield, Massachusetts, and Harpers Ferry, Virginia—received identical mandates from the War Department to develop interchangeable-parts manufacturing for military weapons. Both facilities received the same machines, the same blueprints, the same federal funding, and the same inspections. Springfield adopted the new methods with disciplined efficiency, becoming a model for precision manufacturing. Harpers Ferry resisted for over a decade, not from technological incapacity but from a craft culture valuing worker autonomy and holistic skill over standardized procedure. The divergence was institutional, and it demonstrated with archival precision that organizational culture determines technological outcomes more powerfully than the technology's inherent properties.

Springfield's organizational culture emphasized discipline, uniformity, and compliance with federal directives. The armory operated under strict hierarchical control, with superintendents enforcing standardized procedures and workers expected to follow specifications precisely. This culture aligned with the War Department's priorities: weapons that
