Handmade Reference Book

New United Motor Manufacturing Incorporated (NUMMI) was an auto manufacturing plant in Fremont, California, that was jointly operated by Toyota and General Motors from 1984 until 2010. GM had operated the plant at Fremont from 1960, where the clashes between management and union workers resulted in the plant’s closure in 1982. When it reopened as a joint venture between Toyota and GM, Japanese management techniques had been studied and implemented to emphasize collaboration and teamwork between workers and management. The objects collected from NUMMI came from Judy Weaver (engineering) and Rick Madrid (quality control), who submitted winning essays on the concept of teamwork.
Rich Madrid’s notebook is a handmade encyclopedia of machine-stamped parts produced at the NUMMI plant. Each page contains a small picture of the part as well as its part number, part name, model name, and other pertinent details relating to its production. This book is a prime example of Toyota’s concept of kaizen, or worker-led improvements. The book made it easy for Rick to make sure parts were machined to specifications.
