A good tactical primer on the relatively new field of Product Marketing. I would consider the first 4 chapters more of an overview of Product Management. This is useful because PMMs typically work VERY closely with PMs, and it's crucial to understand what they do and how they do it. But if you're a PMM, you should start with Chapters 5 & 6, and then go back to read the rest.Keep in mind that this is very dry reading. Again, it's a textbook, not "Who Moved My Cheese?" or "The Goal." But it will tell you succinctly what you need to know to get started on the road to success as a PMM. I recommend this book to everyone.
