Now you know the timeline and impact of each idea, it’s time to compare outcomes. To get a CD3 score for each idea, divide revenue by time, and rank the ideas from highest to lowest based on their scores. A higher number means more potential lost income if you wait, and is the one you should put at the top of your list.
In our scenario, we calculated the CD3 score of each idea like this:
- Idea A: $5,850 weekly uplift / 4 weeks = 1463
- Idea B: $4,550 weekly uplift / 2 weeks = 2275
- Idea C: $3,250 weekly uplift / 1 weeks = 3250
In traditional prioritization methods, Idea A would take priority because it has the highest potential outcome. Idea B would follow, and finally Idea C, which would mean incurring the cost of delay of:
- A, B, and C for 4 weeks
- B and C for 2 weeks
- C for 1 week
In total, this amounts to $73,450 of cost incurred through delay.
When we apply CD3, our prioritization changes: we start with Idea C, Idea B follows, and finally Idea A. This way, we incur the cost of:
- A, B, and C for 1 week
- A and B for 2 weeks
- A for 4 weeks
The total cost of delay in this scenario is $57,850, a reduction of 21% versus traditional prioritization methods.
Of course, there could be other factors that impact your decision: for example, the timing of an idea might not work with all of the involved teams, or you might want to involve and delight customers by getting their feedback on your roadmap.
