What Product Management Methodology Should Every Startup Learn and Adopt?

Everything is a hypothesis that needs validation. Your product. Your channels of distribution. Even the way you organise your teams. And it is sensible to assume a null hypothesis: that nobody wants your product and they are not anywhere near as excited about it as you are. 

Thinking in this way forces you to run validation loops and constantly find ways to prove your null hypothesis wrong. That people actually do want your product. They expect to find it in the distribution channels that you are in. And you have the product market fit that you’re striving for. 

Treating every idea as a hypothesis that needs validation forces you to measure the impact of every micro-level product decision you make, through a Build -> Measure -> Learn feedback loop. It enables you to attribute cause and effect to things you ship, since it forces you to state a hypothesis before shipping something and then look to either prove it true or false. If you’re constantly not predicting what your product initiative will do, you will never learn anything. All you will see is just what happens. Taking the guesswork out of product management is essential to consistently shipping value to your customers.
