💎 Testing velocity, success rate and average impact

The throughput funnel for a team is a function of velocity, success rate and average impact:

  • Velocity: how many feature experiences are you putting out per engineer per week? Example at Airbnb: 1 test/engineer per week.
  • Success rate: for 100 experiments, how many are a statistically significant winner that you’re going to roll out? A good benchmark is a 20-30% success rate which means you should expect 70-80% of your test to be flat or negative.
  • Average Impact: if you have a 30% success rate, what’s the average impact over these?

Great interesting short snippets of informative articles. Highly recommended to anyone who loves information and lacks patience.


Don’t look further if you love learning new things. A refreshing concept that provides quick ideas for busy thought leaders.

Ashley Anthony

This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!

Shankul Varada

Best app ever! You heard it right. This app has helped me get back on my quest to get things done while equipping myself with knowledge everyday.

Ghazala Begum

Even five minutes a day will improve your thinking. I've come across new ideas and learnt to improve existing ways to become more motivated, confident and happier.

Giovanna Scalzone

Brilliant. It feels fresh and encouraging. So many interesting pieces of information that are just enough to absorb and apply. So happy I found this.

Jamyson Haug

Great for quick bits of information and interesting ideas around whatever topics you are interested in. Visually, it looks great as well.

Laetitia Berton

I have only been using it for a few days now, but I have found answers to questions I had never consciously formulated, or to problems I face everyday at work or at home. I wish I had found this earlier, highly recommended!
