This chapter presents seven probing questions that guide the reader in creating effective experiments. The first question serves as a starting point for building a strong hypothesis by outlining the key features of effective hypotheses. The second question prompts the reader to assess whether the company is fully committed to the experimentation process and prepared to implement changes based on the results. The third question helps to determine if an experiment is feasible. The fourth question addresses factors that ensure an experiment is reliable. The fifth question provides guidance on how to interpret possible causality in your experimental results. The sixth question helps to ensure a company is going to get the most value out of the results of an experiment. Finally, the seventh question reminds the reader that not every business decision should be based solely on experimental results,and acknowledges the limitations of what experiments can achieve.
