I'm reading "The Art of Product Management" by Rich Mironov.
I've been reading and recommending Product Bytes since it was first introduced in 2002. Each article hits a product management pain point and gives specific tools solving it. "The Art of Product Management" offers the best of Product Bytes plus more.
Henry Chesbrough writes, "Rich is a thought leader among technology practitioners. He balances practical experience with systematic insights into how products are built and what makes start-ups successful. This nbook captures the wisdom he has accumulated, along with considerable scar tissue."
Rather than a book of vague generalities, this book covers the gamut of product management activities and goes deep enough to be helpful. Those who have attended classes by Pragmatic Marketing will find the advice syncs with what you've learned.
