Marty Cagan is certain to upset many people product-people with this article. Read at your own risk.

This article is certain to upset many people. I’m sorry for that, but the degree of ongoing noise and confusion surrounding the role of product at tech companies is only getting worse. Moreover, I see the issues and problematic behaviors getting institutionalized in conference talks, training programs and so-called certification programs for product people.

So while this article might be painful to read, if you’ve been frustrated with the contradictory and confusing messaging from people in the product world, if you bear with me here, I am hopeful that this will provide some much needed clarity.

BTW, Marty and his book INSPIRED was talked about in this recent episode of The Changelog featuring Ryan Singer talking about Basecamp’s new book Shape Up.
