They call it consumer science at Netflix, the ability to test new ideas with customers at scale and measure for statistically different engagements with the online product. They have set up a rigorous a/b integrated testing platform to register and counteract any issues with the platform and to continually push the innovation to satisfy their 80 million+ members.
Innovation involves a lot of failure. If we’re never failing, we aren’t trying for something out on the edge from where we are today. In this regard, failure is perfectly acceptable at Netflix. This wouldn’t be the case if we were operating a nuclear power plant or manufacturing cars. The only real failure that’s unacceptable at Netflix is the failure to innovate.
