You have an idea for a B2C product, for a mobile app even. But you're worried about bugs & bad reviews on app store. So, you only release it for a very limited audience. That's probably wrong...

This post talks about setting a value hypothesis and related KPIs. It’s part of the ‘Product Management in the Open’ series. The goal of the series is describe the process of product managing a mobile app - Best in Town / Best in Edinburgh. This post describes my thinking back in the beginning of 2017. Not everything I did at that time was correct and I also try to reflect on some of the mistakes here.

An idea for the app that is part of the 'Product Management in the Open' series.

This is the first article in the series about working on a mobile application - Best in Town / Best in Edinburgh - and applying the Lean Startup methodology and other good product management techniques.

Why do you need to split user stories? Often, you hear that it is important to split user stories.

More likely than not, you’ve come across a message like: TypeError: Cannot call method 'someMethod' of undefined Your browser or the Node.js interpreter will tell you in which file and on which line that error has occurred. Then, you’ll start a very mundane task of examining the code of a 3rd party library, if it’s has not been minimised, of course. Eventually, you will find out that you have forgotten to provide one of the arguments required by a function. You may even see a more obscure error.
