DIE stands for Demand, Impact and Effort. DIE is probably the simplest of all the frameworks. If you have not read why you need a framework, I suggest you read it first.
Demand (D)
Indicates how strong the demand is for a feature. Note that the word "demand" implies that there is sufficient evidence that your customers are demanding this feature.
Demand can be "high", "medium" or "low". High is usually assigned 1, medium a 2 and low a 3.
If there is no evidence of demand, err on the side of caution and assign a "low" value of 3.
Impact (I)
Indicates the potential impact on the customers for a given objective.
Like "demand", "impact" can also be classified as "high", "medium" and "low" with scores of 1, 2 and 3 respectively.
Effort (E)
E is the effort involved from the entire product and engineering team.
Effort can be in following t-shirt sizes: XS, S, M, L and XL with scores from 1 to 5.
Formula
Simply adding up the D, I and E values will generates the DIE-score for the feature.
DIE Score = D + I + E
The feature with the lowest DIE score must be prioritized first.
