Execution is where the real value lies.
Let’s break it down with a simple formula: Value = (Dream Outcome × Probability of Achieving Outcome) ÷ (Effort × Time Delay).

How big is the impact you can make?
2. Probability of Achieving Outcome: This is your chance of success.
How likely is it that your product will achieve the dream outcome?
- Effort: How much work is required?
