Learning to see waste and systematically eliminate it has allowed lean companies such as Toyota to dominate entire industries. Lean thinking defines value as 'providing benefit to the customer'; anything else is waste.

In the old economy, it was all about having the answers. But in today’s dynamic, lean economy, it’s more about asking the right questions. A More Beautiful Question is about figuring out how to ask, and answer, the questions that can lead to new opportunities and growth.

When blame inevitably arises, the most senior people in the room should repeat this mantra: if a mistake happens, shame on us for making it so easy to make that mistake.

The goal of a startup is to figure out the right thing to build-the thing customers want and will pay for-as quickly as possible. In other words, the Lean Startup is a new way of looking at the development of innovative new products that emphasizes fast iteration and customer insight, a huge vision, and great ambition, all at the same time.

I asked all of our recruiters to give me all resumes of prospective employees with their name, gender, place of origin, and age blacked out.

The minimum viable product is that version of a new product which allows a team to collect the maximum amount of validated learning about customers with the least effort.
