The article by john-krafcik published in MIT Sloan Management Review in Fall 1988 that first used the term "lean production." Krafcik was a master's student at MIT Sloan studying under james-p-womack, and the article was based on his master's thesis. The coining of the term in this article is the origin point documented in krafcik-lean-production-origin.
Significance: the naming of lean
This article is the etymological origin of "lean production" as a term. Krafcik needed a name to describe the production system he was analyzing in his comparison of automotive assembly plants — a system that used fewer resources (less inventory, less space, fewer workers per unit) than conventional mass production while achieving higher quality. He chose "lean" to capture the resource-efficiency dimension.
The naming was consequential beyond its accuracy. By calling the system "lean" rather than "Toyota Production System" or "JIT production" (the terms then in use), Krafcik's framing emphasized the waste-elimination dimension and made the system sound portable and universal. This framing shaped how machine-that-changed-the-world (1990) presented the system and how the lean movement understood itself for decades.
Krafcik's role in the IMVP
Krafcik was a researcher in the mit-imvp program. His empirical work on plant-level productivity comparisons was a key input to the IMVP study that produced machine-that-changed-the-world. The article draws on the same data as the larger study but was published two years before the book, establishing the terminology in advance.
What TPS concepts are being translated
Krafcik's analysis compared assembly plant performance across manufacturers and countries. The "lean" framing abstracts from TPS's operational specifics to focus on measurable outputs: hours per vehicle, defects per vehicle, inventory days. This metric-focused translation complemented Womack and Jones's later conceptual translation — Krafcik provided the empirical evidence; Womack and Jones provided the explanatory framework.
Notes on authorship and KB placement
Krafcik is the sole author; Womack and Jones are not co-authors of this article. The article is included in the womack-jones KB because it is a direct product of the IMVP program Womack led and because it coined the term that defines the entire KB subject area. The mit-imvp entry documents the program context.
