Its origin and development was in Japan, largely in the 1960s and 1970s and particularly at Toyota. Alternative terms for Lean warehouse management pdf manufacturing have been used.
John Constanza at his Institute of Technology in Colorado. Still another alternative was mentioned by Goddard, who said that “Toyota Production System is often mistakenly referred to as the ‘Kanban System'”, and pointed out that kanban is but one element of TPS, as well as JIT production. The exact reasons for adoption of JIT in Japan are unclear. Plenert offers four reasons, paraphrased here.
During Japan’s post-World War II rebuilding of industry: 1. Japan’s lack of cash made it difficult for industry to finance the big-batch, large inventory production methods common elsewhere.
Japan lacked space to build big factories loaded with inventory. Japan had high unemployment, which meant that labor efficiency methods were not an obvious pathway to industrial success. Thus the Japanese “leaned out” their processes. In this way, inventory levels were kept low, investment in in-process inventories was at a minimum, and the investment in purchased natural resources was quickly turned around so that additional materials were purchased.
Plenart goes on to explain Toyota’s key role in developing this lean or JIT production methodology. TPS reached western shores in 1977 in two English-language articles: One referred to the methodology as the “Ohno system”, after Taiichi Ohno, who was instrumental in its development within Toyota.
