Experimentation

Library search, filter and results

Build on what the testing programme has already learned, instead of running an old idea again because nobody could find the first one.

Searches hypothesesFilter by outcomeOpens in place

The experiment Library now doubles as a record of what your testing programme has learned. A test is remembered by what it was about more often than by what it was called, so search reaches into hypotheses, notes, expected mechanisms and variant names, not only the name.

That means “that test about delivery dates” is found in seconds, along with whether it won. It is the difference between building on an old result and quietly running the same idea again.

A filter narrows the list by outcome (won, lost, mixed or inconclusive) and by expected mechanism, which shows which kinds of change have worked for you and which have not. A Result column puts each finished test's outcome and lift in its row, and the outcomes match the ones the Program report counts.

Any row opens in place to show the hypothesis, the expected mechanism and what the test found, so reading back through a quarter's results does not mean opening a quarter's experiments one at a time.
