Q & A
What is the key to efficiency in Japanese factories as described in the script?
-The key to efficiency in Japanese factories is the careful and neat arrangement of tools and working materials, which reduces the time spent looking for tools and minimizes the time spent transporting materials to workspaces.
What does the Japanese word 'Kaizen' mean in the context of the script?
-In the context of the script, 'Kaizen' means to continuously improve work efficiency and safety through small, incremental changes in work processes.
How does the concept of Kaizen contribute to the workflow on the shop floor?
-Kaizen contributes to the workflow on the shop floor by encouraging workers to constantly think of ways to improve procedures, such as taking fewer steps or reducing the time needed for certain tasks, which leads to significant overall improvements.
When and where did the idea of Kaizen begin?
-The idea of Kaizen began about 70 years ago in automobile plants in Japan, where workers shared their knowledge to revise and improve work procedures, contributing to Japan's rapid economic growth.
How did the sandwich factory implement Kaizen to improve its production process?
-The sandwich factory implemented Kaizen by changing from a linear flow to a system where small groups of workers complete batches of sandwiches, rearranging work benches and assigning multiple processes to each worker, which sharply reduced the time required and increased productivity.
What was a major goal of the Kaizen effort in the sandwich factory regarding workers with disabilities?
-A major goal of the Kaizen effort in the sandwich factory was to make it easier and more comfortable for workers with disabilities to do their jobs by redesigning trash receptacles for easy transportation and providing various assistive devices.
What was the Kaizen idea implemented by a worker to stabilize hanging screwdrivers?
-The Kaizen idea implemented by a worker to stabilize hanging screwdrivers was using flexible cords, which reduced wasteful movement and saved as much as 200 minutes of work time a month.
How are spares and supplies arranged in the factory to assist visually challenged workers?
-Spares and supplies are arranged for easy handling by visually challenged workers, with tapes arranged by type and large paper discs indicating by touch when only one is left, and the discs' bright printed design delivering information clearly to sighted people.
What is the purpose of the carjacks in the work tables?
-The purpose of the carjacks in the work tables is to allow them to be raised and lowered to match the height of each worker's wheelchair, making the work environment more accessible and comfortable for everyone.
How has the Kaizen approach impacted productivity, quality, and working conditions in the factory?
-The Kaizen approach has improved productivity, quality, and working conditions in the factory by simplifying work processes and making tasks easier for everyone without the need for new equipment.
Why is Japan's Kaizen approach gaining followers around the world?
