A dozen years ago, Andy Grove’s Only the Paranoid Survive came out. I had cause to pick it up again today.
You can find (most of) the preface online at Intel. Here’s the key definition: “a strategic inflection point is a time in the life of a business when its fundamentals are about to change.”
In order to describe the fundamentals of a business, Andy extended Michael Porter’s Five Forces of Competition model into a Six Forces model. The force he added was that of complements. For example, Microsoft Windows was an important complement to Intel’s chips, and remains so today.
OtPS is a Six Forces account of Intel and its environment. That said, it is a dozen years old, and that’s a long time in a tech industry. The risk of obsolescence is particularly acute when we realize that the last chapter is “The Internet: Signal or Noise? Threat or Promise?”, opens with the then-recent story of Netscape’s IPO, and goes on to explain what the internet is. But the chapter stands the test of time remarkably well.
So does the book as a whole. I expect to be able to rate OtPS as highly in another dozen years, for the clarity of the six forces framework and Andy’s exposition.
