Cohort-based Course

Learn from a world-leading expert the essentials of accelerating innovation with trustworthy A/B tests. Recorded videos and live sessions.

Course overview

Empower your organization to be data-driven and innovative

NOTE: this video with live sessions course is designed for private (at least 30 people) or semi-private ( at least 20 people from your company; you pick the dates, others can join). Sign-up for the waitlist and reply to the email if you are interested in scheduling a class.

Through multiple real examples of well-run experiments and real stories at Microsoft, Amazon, and Airbnb, you will see the humbling reality that we are terrible at assessing the values of ideas.

Trivial changes can be surprisingly useful, whereas large efforts often fail. A/B testing allows you to evaluate changes and accelerate innovation by building Minimum Viable Products and Features (MVPs). The organization becomes evidence-based and humbler, as it adopts and learns to use evidence from the gold standard in science: the controlled experiment.

You will understand the challenges in designing and running trustworthy controlled experiments, or A/B tests, including the importance of the Overall Evaluation Criterion (OEC), scaling, pitfalls, and Twyman's law.

Learn the essentials of A/B testing by watching easy-to-consume videos at your own pace, ask questions on the Maven questions channel, and attend two interactive one-hour sessions for fun polls and Q&A.

Who is this Course For?


Organization leaders (VPs, directors, managers) interested in understanding the essentials of A/B testing to accelerate innovation


Program managers focused on growth, revenue, conversions, and prioritization who will understand how to better design robust clear metrics


Data science managers and scientists who do not need or want the 2nd part of (or prefer videos)


Anyone interested in making the organizations more data-driven and efficient with fewer severe incidents

What you will learn from this course

Understand and internalize the humbling reality that we are poor at assessing the values of ideas: most ideas fail!

You will hear multiple real memorable stories and examples, many that don't make it to books or articles. These were chosen from over 20 years of experimentation. You'll have the data to show that the poor success rate is documented across multiple organizations; expected it!

Understand the key advantages and limitations of A/B testing

Understand key concepts like causality, hierarchy of evidence, and key organizational tenets required for effective experimentation.

Learn how to design metrics and the Overall Evaluation Criterion

Designing metrics is hard. There is a hierarchy of metrics and perverse incentives. The most important metrics comprise of the OEC - The Overall Evaluation Criterion. We will look at good and bad examples.

Learn how to designing trustworthy A/B tests

Getting numbers is easy; getting numbers you can trust is hard. You'll understand common pitfalls and how to design reliable and trustworthy tests.

Learn how to generate and prioritize ideas

You'll understand the key tradeoff between the cost and fidelity of different methods. You'll learn about the key concept of EVI: the Expected Value of Information. You'll learn about different prioritization frameworks.

            Ronny made the content amazingly easy to consume...I can't recommend it enough

            If you're interested in running A/B tests and learning the science behind them, my highest recommendation is to take Ronny Kohavi's cohort-based course on the topic. (The book Ronny co-authored is tied for first on my reading list too.)

            The entire course and the way it was delivered was amazing - had tons of learning, especially on where we could go wrong. Examples followed by key concepts was great. Really appreciate Ronny taking time to answer each question even after the session.

            The culture of Q&A during the session. The depth and width of the experimentation topic. Really eye-opening learnings from Ronny. Thank you, thank you, thank you!

            I love Ronny's stories. I think that apart from the learning, two of the most valuable things from this class are: 1) Stories because you will remember them and they will come in handy and 2) Links so that you can dive deeper.

            50% of what I've learned myself about experimentation is wrong. The other half I learned from Ronny.

            Favorite part: Practical info and learnings that weren't in the book but were probably not easily publishable.

            This is an amazing opportunity. I think of all of the times I have questioned, “does X make sense?” I saved up all of those questions. I’ll tell you that Ronny Kohavi covered MANY of them in his lecture content (so I didn’t have to ask those). It was so powerful to just ask directly. Easily saved me hundreds if not thousands of hours of research.

            Just had an incredible experience as the entire leadership team at Vinted Marketplace joined me in the 'Accelerating Innovation with AB Testing' course by Ronny Kohavi himself! 💪🔥 …Let's take our experimentation game to the next level!
