Own the fucking product
Cut the crap. Seriously, just cut the shit which is buggy or unused. Focus on making the core experience great. Good is a low target.
‘Good is better than perfect’ but ‘great’ is better still. Aim for great, don’t aim for ‘good’. For some reasons many product owners seems to loose focus and instead waste resources (time, money, words) on stuff which has failed. It’s not a ‘bet’ if you unwilling to decide what failure looks like.
I believe, simply put, that for a great project you require focus. To provide focus you have to work to remove the crap. Decide what matters most and decide a number which represents appropriate effort for a given feature. If 1% of people use it and it takes 10% of resources then your not being a product owner, your pretending.
Make decisions, revise decisions test and learn. Own the fucking product.
