Heijunka
Heijunka is production leveling, working to produce only the parts and
products that are needed whilst also keeping all machines and people as
active as possible. This is done by by load balancing and sequencing orders in a repetitive
pattern and smoothing the day-to-day orders to correspond to longer-term
demand. Heijunka can be used to help create pull in a system rather than
the more problematic push, thus helping to remove bottlenecks and reduce
inventory. Thus, for example, people might move between working on different jobs
and building a blend of different products.
