Howard Schultz envisioned an Italian espresso bar in Seattle. He tested this hypothesis and found it wanting. But the test produced additional information, so he modified his hypothesis and retested. After hundreds of iterations, the original hypothesis has long since vanished, replaced by a myriad of new hypotheses, each covering some aspect of the growing, evolving business. This process of learning—hypothesis, data, anomaly, new hypothesis, data, and so on—is called scientific induction and is a critical element of every successful business.
