Inspired by Ron Pereira's multi-part blogging about heijunka this week, at the Lean Six Sigma Academy, including heijunka in the front office, here is a new kaizen song.

Hey, Juneka (heijuneka)
(to the music of The Beatles' "Hey, Jude")

Heijuneka, don't make a batch
Fill one order, then fill another
When salesmen place orders in small amounts
Then you can start to make the load flatter

Heijuneka, won't be a sinch
You need an al-gorithmic pattern
The minute you average volume and mix
Then you begin to make the load flatter

And any time your markets change, heijuneka, retrain
Don't carry the stock within your processes
Well don't you know that it's a fool who calls it pull
By selling his stock through discount dealers

ABABABAABAA CABACAABAA!

Heijuneka! The foundation
Makes flow smoother and schedules stabler
Endeavor, SMED set ups for all your parts
Then you can start to make the load flatter

Not product-out but market-in, heijuneka, as in
You're making only what they are buying
And don't you know that just in time, heijuneka,
Will need, lot sizes to be, oh so much smaller

ABABABAABAA CABACAABAA!

Heijuneka, don't make a batch
Fill one order, then fill another
When salesmen place orders in small amounts
Then you can start to make the load flatter

Flatter, flatter, flatter, flatter, flatter, yeah!
AABAABAA CABACAABAA CABACAABAA heijunka!
AABAABAA CABACAABAA CABACAABAA heijunka!
