Early Paperback Errata
Thankfully, due to print-on-demand technology, these initial errors will be corrected shortly. Even though the book went through multiple proofreading passes by professionals, small defects still get through. My apologies.
Front cover: The blue lines around “OF” were misaligned vertically in some printings.
Back cover: “the Lean” should have said “the Lean methodology” and has just been removed from future printings.
Page 67: The chart is monthly data, but was incorrectly labeled “weekly.”
Page 124: Typo of “Softwar-development”
Page 157: The chart has an extra data point.
Page 157: The x-axis dates are incorrect and should be the same as the chart on Page 156.
The charts on Pages 156 and 157 should look like the following and will be corrected in future printings.
Page 157: The last paragraph mentions September 2008 and asking “Why was the metric so good that month?” — but should refer to October 2008.
Page 170: On the chart, the orange legend text says “Dec 2010 – Nov 2010” (should be Nov 2011).
Page 184: Last paragraph says “April 2018” when it should read “April 2016.”
Page 181: The dashed line on the chart should be at 44, but appears to be more like 41.
Page 194: Typo of “ssafe-driving”
Again, my apologies. These will all be corrected for future printings ASAP.
Early eBook Errata
The following are changes that have been made in the eBook since its initial publication in August 2018. The eBook has been updated for new purchasers. These errors are not in the print edition.
- The X chart for the number of Oscar telecast viewers erroneously had the years 1991, 2002, and 2013 appear twice in the X-axis. The last data point should have been labeled 2018 instead of 2017.
The chart should look like this (click for a larger view):
- In the discussion of the Oscars, the sentence “The data and charts show that 2008 was the lowest year in recent history by a small margin” should have said that 2018 was the lowest year.
- In the section about the surgical deaths simulation, “there were 10 deaths in Period 2″ should have said Period 4.
I apologize for any errors.
