How to Find YOUR 80/20
Step 1: List Everything
Write down ALL activities in the area you're analyzing:
- What do you spend time on?
- What generates results?
- What costs money/energy?
Step 2: Measure Impact
For each activity, estimate:
- Input: Time, money, or energy spent (% of total)
- Output: Results generated (% of total)
- Ratio: Output ÷ Input
Example:
| Activity | Input (%) | Output (%) | Ratio |
|---|---|---|---|
| Cold email | 30% | 5% | 0.17 |
| Referrals | 10% | 45% | 4.5 |
| Content | 25% | 30% | 1.2 |
| Paid ads | 35% | 20% | 0.57 |
Step 3: Rank and Cut
- Double down: Top 20% by ratio (Referrals in example)
- Optimize: Middle 40% (Content, Paid ads)
- Eliminate: Bottom 40% (Cold email)
Step 4: Validate with Data
Don't trust gut alone:
- Pull actual revenue by customer
- Track actual time by activity
- Measure actual results by channel
