Marketing Managers Do any of these problems sound like your life? We chase any market that comes along. Development codes what is cool, not what is needed. My developers create products that only other developers can use. My product managers just react to other departments. We practice "Field of Dreams" planning: Build it and they will come. How many product managers do I need? How should I divide the product management resources I have? Our market segment size is "1": whatever the latest deal found by sales. Sales is making things up. Sales doesn't look at training material, they just call product management. I don't know why we win or lose deals.
