A PHD or Product Hypothesis Doc outlines the overarching research question a particular study is trying to answer. It serves as a contract of sorts between all parties involved in the study to identify what we are ACTUALLY trying to accomplish and how we will measure if we have achieved that result. The PHD is eventually pasted into the bug for launching the study.
