Besides being fairly short, and having a lot of general good advice, such as, to use my own wording, making sure every essential hat is worn by someone, e.g. you probably won't start out with a CFO, but make sure one of the founders or earliest employees wears it, it goes into a thesis that you should write up a manual of how your business runs as if you were going to franchise it.
Plenty of good justification for writing this up at some level of detail can be found in the other comments in this topic, although I'll admit the book is not oriented toward high tech businesses.
But they're still businesses, and for that focus I highly recommend, probably after one or more books on customer development, which refine many of the ideas in it, Walking the High-Tech High Wire: The Technical Entrepreneur's Guide to Running a Successful Enterprise (https://www.amazon.com/Walking-High-Tech-High-Wire-Entrepren...). It's a story about a company that made and sold novel at the time discrete semiconductor devices, how they did their customer development, how they realized doing custom work for various customers was a loser, etc. It'll help reify what you'll read in good customer development books.
But it's silly that Amazon is selling them for more. Often times much more.
Not by choice. Amazon tried to set some reasonable price points, and the big five refused to play ball (remember their conspiracy with Apple?), ultimately renegotiating their contracts to agency pricing. Which is why so many of their books cost so much now.
By now they could well be subsumed in e.g. Steve Blank's work, but it's not a long read and the price is right. And they walked the walk: they developed a device that the could fabricate on a lab table top, but it required different thinking from hardware designers. That plus their quasi-pivot (actually just doing the numbers and figuring out which of the two businesses they were doing (selling parts and consulting) they should focus on) are also worthwhile, even or especially if you're in software.
It worked, in that he achieved both objectives and the company went public. The problem from the VC's point of view is the longer term....
This brings out one other point, which for illustration I'd like to turn around to something we're all familiar with: how much do you charge?
If you're to be successful in sales it has nothing to do with e.g. how much are your costs.
In fact, your general approach should be more one of "What is the right price and where does that leave us?"
One of many important lessons to be found in my favorite high tech company development book, Walking the High Tech High Wire (http://www.amazon.com/Walking-High-Tech-High-Wire-Entreprene... or http://www.amazon.com/Walking-Technical-Entrepreneurs-Succes...)
Walking the High-Tech High Wire: The Technical Entrepreneur's Guide to Running a Successful Enterprise (https://www.amazon.com/Walking-High-Tech-High-Wire-Entrepren...). Pretty cheap used.
