Having a clear test plan is a MUST for any A/B Tests.
There is no shortcut.
There is no assumption to be made.
To develop a test without the full test plan is like getting a flatpack furniture delivered without clear instructions to build it!
If you spend a few minutes extra to make sure that the test plan and the design of the variations are clarified, you will save hours of back and forth related to the test. Trust me – I have been there!
It does not matter who is developing and QAing the test, the Test plan needs to make sure that everything is covered. Whether they are targeting related, metrics related or handling different scenarios.
Use a template for the test plan if necessary that will always make sure that you are filling the required sections for your experiments.
Here is a test plan template – feel free to use it!
