Experiments

How to read a page

Every page is one experiment in the shape the loop on the front page runs: problem, evidence, cohort, hypothesis, the exact change, the primary metric and its window, guardrails, traffic plan and decision rule. The chip on every card says what kind of object it is. An example shows a pattern and carries no expected impact and no result, by design: there is no field on it that could hold a number. A reported experiment is somebody else's public write-up, cited. A measured one is run with permission, and there are none yet: no customer has run an experiment through Athren, so nothing here is an uplift figure of ours.
