One thing I observed with some (most) of the Phocuswright innovators is that a lot of the products demo-ed are (still) conceived and created by engineers. Engineers are brilliantly smart. But most suffer from the “because we can” syndrome. FAIL.

Good products are simple and useful. If you don’t meet these criteria, you will fail guaranteed. Meet them, and you have a shot. They are your minimum requirements.

Take Twitter. Turns out Twitter us useful to millions of people. Twitter is also extremely simple. Post and follow. That’s pretty much it.
Twitter could add categories, replies, forwards, tags, google maps and much, much more. Twitter could allow its users to add pictures, voice messages, video. But they have resisted. Because it would stop being simple. And that’s a big reason why Twitter is successful.

Take Kayak. Kayak is also useful. Kayak is also extremely simple in it’s essence. From->to->dates->search and you’re done. The result page focuses on the core task; find the best flight. Features are optional after the core task is completed. These features are useful in itself, but don’t stop the core task from being simple.

I suggest to all the innovators to hire a product manager who understands this, focuses on the core task that’s being satisfied, and strips everything else.
