Impact Mapping: Connecting Deliverables to Business Outcomes
Impact Mapping is a technique created by Gojko Adzic that answers a fundamental question: “Why are we building this?”
The Impact Map Structure
Answer 4 questions in order:
1. Why? (Business Goal)
“Increase revenue by 20% next quarter.”
2. Who? (Actors)
Who can help or hinder this goal?
- New customers
- Existing customers
- Sales team
3. How? (Impacts)
How can each actor contribute?
- New customers: sign up more easily
- Existing customers: buy more frequently
- Sales team: close bigger deals
4. What? (Deliverables)
What can we deliver to create these impacts?
- Social login (reduces signup friction)
- Personalized recommendations (increases purchase frequency)
- Analytics dashboard for sales (closes bigger deals)
Visual Impact Map
Why: Increase revenue by 20%
├── Who: New customers
│ └── Impact: Easier signup
│ └── Deliverables: Social login, One-click signup
├── Who: Existing customers
│ └── Impact: More frequent purchases
│ └── Deliverables: Recommendations, Discount coupons
└── Who: Sales team
└── Impact: Bigger deals
└── Deliverables: Analytics dashboard, Automated proposals
Impact Map + Estimates
Impact Mapping makes estimates more valuable:
“Social login: 8 points. Social login → +15% new customer signups → $50K/month in additional revenue.”
Now we know that 8 points generate $50K. Compare with:
“Analytics dashboard: 21 points → +10% deal size → $30K/month.”
Social login is more efficient per point invested.
Prioritizing with Impact Map
ROI per Point
| Feature | Estimated Impact | Points | ROI/Point |
|---|---|---|---|
| Social login | +$50K/month | 8 | $6.25K/point |
| Coupons | +$20K/month | 5 | $4K/point |
| Dashboard | +$30K/month | 21 | $1.4K/point |
| Recommendations | +$40K/month | 13 | $3K/point |
Prioritize: Social login > Coupons > Recommendations > Dashboard
When to Use Impact Map
- Quarterly planning — align deliverables to objectives
- Prioritization workshop — with PO and stakeholders
- Product kickoff — define initial roadmap
- Portfolio review — justify or cancel initiatives
Anti-Patterns
Generic Map
Goal: “Improve the product.” — that’s not a goal. It must be measurable.
Deliverables Without Impact
“Refactor the database” → not connected to any actor or impact. It shouldn’t be on the map (or it should be tied to an efficiency impact).
Too Many Actors
If you have 15 actors, the map is too big. Group them by categories.
Conclusion
Impact Map connects technical work to business outcomes in a visual and transparent way. Teams that know why they are building something estimate better, prioritize smarter, and deliver with more purpose.
