ICE Prioritization Done Right

With ICE we assign each idea three values:

Impact – how much does this idea stand to improve the key metric we want to grow. I explain below what this key metric is.
Confidence – how sure are we that we will have this impact? Another way to put this— how strong is the evidence in support of our impact assessment.
Ease – how easy is it going to be to build and launch this idea in full. Usually this is the opposite of person/weeks.
