Product teams, fortunately, are not creating new knowledge. Instead, we are trying to create products that improve our customers’ lives. When we launch a new product or service, we get to see how our customers interact with it. This is a fantastic feedback loop. We quickly get to measure if our product had the intended impact. We work on much faster cycles than science. It took almost 100 years before we could collect physical evidence to support Einstein’s theory of general relativity.
