As a crazy fast reader I liked it but now that I think about it, problems with product quality were a major preoccupation of the 1970s. There is a triangle between

  inflation <-> poor quality <-> shortages

in that these all stem from the same root and the proportion in which they manifest depend on the system (e.g. in Soviet Russia they could legislate prices but couldn't legislate availability of products) It was the decade of Ralph Nader. See

A few themes could be broken out, not least "mongo sucks" (I never worked at a company that didn't trust the database they used at all until I worked at one that used mongo) and a meditation on "buy" vs "build" that leans heavily towards build. (When I hear the word "integration" I reach for my keyboard and code up a 15-line python script while management is on hold waiting to hear what the "call us" price is)

Somewhat agree. If you really want to understand lean principles, start with the masters of the topic and consider reading some books about Toyota. The first in the list below is a wonderful introduction to how lean manufacturing principles evolved at Toyota over decades. The others can provide more hands on experience on the topic and if you can mentally translate manufacturing principles to software construction techniques, everything will start to make sense.
