Errata

The word "theCir" should be "their"

The second bullet ("Mura") is missing a closing quotation mark

"for example)" -- change the ")" to an em hyphen

I believe there is some contradictory information in the text (unless I’ve misunderstood). This is in Chapter 9 (Kanban) - summary below:

• Page 344 references Little’s Law as W = L ÷ λ. That is, the average lead time (W) is equal to average inventory (L) divided by average lead time (λ).
• The diagram in page 343 states “Little’s Law says that when a system is stable, the average lead time for all work items (W) is always equal to L times λ.” (i.e. W = L x λ). This contradicts the formula on page 344 (W = L ÷ λ).
• Page 361 has the same contradiction. The fifth bullet in the “Key Points” section states “When a system is stable, Little’s Law applies, which means that the average lead time is always equal to the long-term arrival rate times the long-term inventory.” (i.e. W = L x λ)

Apologies if I’ve misunderstood, but thought I would point it out.

Note from the Author or Editor:
Yes, there's a typo in figure 9-10 on page 343. For the production team: here's a link to a PDF of the updated diagram with the typo fixed: http://bit.ly/1Aq12se

The same typo is also on page 361 in the third bullet -- change "times the long-term inventory" to "divided by the long-term inventory"
