In Chapter 1, we reviewed what controlled experiments are and the importance of getting real data for decision making rather than relying on intuition. The example in this chapter explores the basic principles of designing, running, and analyzing an experiment. These principles apply to wherever software is deployed, including web servers and browsers, desktop applications, mobile applications, game consoles, assistants, and more. To keep it simple and concrete, we focus on a website optimization example. In Chapter 12, we highlight the differences when running experiments for thick clients, such as native desktop and mobile apps.
