This lesson introduces the overarching design of experiments process: the gold standard for answering questions in an objective, efficient, and scientific way. This methodology is applicable to any and every aspect of testing, from characterizing performance, to assessing system reliability, to understanding how humans interact with the system. Planning is a critical element of this process and requires collaboration and iteration among subject matter experts. Specifically, test planning involves identifying the test objectives, determining the appropriate outcome measure(s), and identifying what factors may influence those outcomes.
