The PIE prioritisation framework
Chris Goward’s PIE framework identifies three important factors for prioritising tests:
PIE
Potential
How big of an uplift do we estimate that the change will bring?
Importance
How much traffic does the page get and are you investing a lot to get those visitors?
Ease
How simple is it to implement the fix?
Step 1
Start by listing the tests you need to carry out on your mobile site.
Step 2
Assign a score for the potential increase of conversions the page will give.
Step 3
Assign a score for the value of the page’s traffic for your business and how important it is for ROI.
Step 4
Finally, talk to your developers and ask them to assign a score for how easy it will be to design and implement the fix.
