Application
The Influence Stack

- [ ] Share user research and customer quotes
- [ ] Show ROI/impact projections
- [ ] Acknowledge when you're wrong
### 3. Alignment (Shared Goals)
- [ ] Connect your ask to their goals/OKRs
- [ ] Frame decisions as "us" not "me vs. you"
- [ ] Find the win-win before the meeting
- [ ] Understand their constraints
### 4. Communication (Execution)

Common Scenarios
| Scenario | Approach |
|---|---|
| Eng says "no" | Understand the constraint; negotiate scope, not deadline |
| Exec overrides | Ask "what would convince you?"; bring data next time |
| Sales wants feature X | "Let's test the hypothesis behind that request" |
| Design disagrees | "Let's prototype both and user-test" |
| Team is burned out | Protect them; cut scope; show you care about sustainability |
Quality Rubric
| Dimension | 0 | 1 | 2 |
|---|---|---|---|
| Trust | Unreliable | Sometimes delivers | Consistently trustworthy |
| Evidence | "I think" | Some data | Data-driven with user research |
| Alignment | "Do what I say" | Explains rationale | Connects to their goals |
| Communication | Same pitch for everyone | Audience-aware | Tailored + concise per audience |
