I'm currently building a product for WiredScore. We're not talking about the product publicly, so that's all I'm going to say about it.
To continue learning to be a better product manager, even while I'm practicing, I've been immersing myself in the best talks and videos on product management I can find. This morning while getting ready I watched this great video by Tom Chi on Rapid Prototyping at Google X. And Tom did really rapid prototyping; the first prototype of Google X took him about an hour, and they produced 15 hardware prototypes a week.
If there's one line to take away from Tom's talk it's, "Don't guess, learn." (link goes to a two-minute clip of just that section). Most meetings are "big guessathons." "I think the customer will want this." "I think they'll want that." "Stop guessing, go build the thing, and learn," Tom says. It's good advice. Most of us won't have access to the tools, brainpower, and endless test subjects that Tom had at Google, but I'm going to do my best to stay in this ethos.
