Here is the link to the support site for my Team System book. It contains comments and corrections.

Also, I just found an error today, thanks to a reader:

"In your book on page 179 you put a reference to a figure 8-1 as the Team Model comparison, but the figure shows the Process Model comparison.
Have you ever seen this error ? Do you have the right figure ?"

This should refer to figure 8-4
