In reality, I'd argue that the majority of companies only run experiments because it is considered "good practice".
Acquisition Experiment: Let's put 500$ into Quora ads and see how many registrations we get.
Conversion: Let's embed an alternative CTA via Calendly on the pricing page
Activation: Trigger an automatic email if the registered user has not yet published his first draft
I have heard many of those examples and I am sure you have heard those too.
But from your experience, how do you actually make sure that experiments build upon each other with the goal of understanding a particular area better rather than running one-off tests that stand alone?
