assumptions. The lean startup methodology draws a

lot from this approach, which is pretty common in the

world of science. For example, psychology relies heavily

on experimental methods to test theories about human

Measuring only the right things is one of the

competitive advantages that you can have over bigger

players. They have way too much money and too many

resources to stay focused! When it comes to analysis,

being small actually helps! You can’t allow any waste,

because it may put you out of the business. When big

players dive into data, postponing the decision for

months, you can test a couple of assumptions based on

your small, but accurate, set of metrics. Isn’t that just

great?

Agility is your greatest power. Use it wisely and may

the force be with you.

All right, but how do you decide what to measure?

There are two sets of metrics that you need to take into

account: economic metrics and behavioral metrics.
