This was one of the many books on Downsizing and managing a company during a poor economy that I bought during my first recession, which almost killed off my first company. I do remember reading it in one sitting, and applying the ideas - along with fixes from other books of this ilk - during the 1989 recession in Toronto.
They were valuable because I learned a valuable lesson about planned downsizing: it does not work in a crisis. After a few months I found that these elegant fixes were too little and frankly had no real effect. I savagely cut expenses and tracked down alternate sources of business income, selling ingredients to factories as a way of offsetting the recessionary killing field of my customers. It worked but these books brought me to that conclusion faster than if I muddled around trying to small-fix problems.
Ironically 11 years later I would forge this lesson and have to relearn it again, where it is here to stay.
This book is now basically quaint, historical, and basically not very practical for a small business since it talks about larger organizations. In my office more due to nostalgia.
