What is Validated Learning of Lean Startups?

Validated Learning is a "rigorous method for demonstrating progress when one is embedded in the soil of extreme uncertainty in which startups grow. It is the process of demonstrating empirically that a team has discovered valuable truths about a startup's present and future business prospects" (Ries p. 38). 

According to Eric Ries, the author of "The Lean Startup," the best metrics must feature 3 A's—Actionable, Accessible, and Auditable:

What is Actionable?

An actionable metric is able to demonstrate perfect cause and effect, which makes it clear what actions would be necessary to replicate the good results and avoid the bad ones. Its opposite is a vanity metric that cannot be acted upon. 

What is Accessible?

This means making metric reports understandable. Some tactics for achieving this include using tangible, concrete units; employing cohort-based reports and analyses; providing open access to the reports. 

What is Auditable?

The date is capable of verification so as to be highly credible to everyone. This might include hand testing all day or spot checking with real customers. This might also mean using tools that are not too complex to understand in performing the audit.
