# Module 06: Trigger Mapping

## Lesson 11: Feature Impact Scoring

**Systematic Feature Prioritization**

---

## The Problem with Traditional Prioritization

How do most teams prioritize features?

**Common approaches:**
- "The CEO wants it" (politics)
- "It seems important" (gut feeling)
- "Competitors have it" (copying)
- "Users asked for it" (squeaky wheel)
- "It's easy to build" (convenience)

**The result:** Random feature lists with no strategic foundation.

---

## The Feature Impact Approach

Feature Impact Scoring connects features directly to your Trigger Map:

**The logic:**
1. You've prioritized target groups (Workshop 4)
2. You've prioritized their driving forces (Workshop 4)
3. Now score each feature: How well does it address top drivers?
4. Features with highest scores = highest strategic impact

**The result:** Data-driven prioritization based on user psychology and business goals.

---

## How the Scoring Works

### Step 1: List Your Features

Brainstorm all potential features:
- Ideas from Product Brief
- Stakeholder requests
- Competitor features
- User feedback
- Team suggestions

**Aim for:** 10-20 features to evaluate

### Step 2: Set Up the Scoring Matrix

Create a matrix with:
- **Rows:** Your features
- **Columns:** Top 5-7 prioritized driving forces
- **Cells:** Impact scores (0-3 scale)

### Step 3: Score Each Feature

For each feature, ask: "How well does this address [driving force]?"

**Scoring scale:**
- **3** = Directly addresses this driver (core solution)
- **2** = Significantly helps with this driver
- **1** = Somewhat related to this driver
- **0** = Doesn't address this driver

### Step 4: Calculate Total Scores

Sum the scores across all drivers for each feature.

**Higher total = Higher strategic impact**

### Step 5: Rank and Prioritize

Sort features by total score to create your prioritized roadmap.

## Generic Example

### Context

**Top Target Group:** Remote Team Leads

**Top Prioritized Drivers:**
1. Fear of team burnout without noticing (Negative - Priority 1)
2. Want to demonstrate effective leadership (Positive - Priority 2)
3. Fear of losing top performers (Negative - Priority 3)
4. Want to build strong team culture (Positive - Priority 4)
5. Fear of missed deadlines (Negative - Priority 5)

### Features to Evaluate

1. Daily team pulse check
2. Async video updates
3. Automated meeting summaries
4. Team workload dashboard
5. Recognition and kudos system

### Scoring Matrix

| Feature | Burnout Fear | Leadership | Losing Performers | Team Culture | Missed Deadlines | **Total** |
|---------|-------------|------------|-------------------|--------------|------------------|-----------|
| Daily pulse check | 3 | 2 | 2 | 1 | 1 | **9** |
| Team workload dashboard | 3 | 2 | 2 | 0 | 2 | **9** |
| Recognition system | 1 | 1 | 2 | 3 | 0 | **7** |
| Meeting summaries | 0 | 1 | 0 | 1 | 2 | **4** |
| Async video updates | 1 | 1 | 0 | 2 | 0 | **4** |

### Prioritized Roadmap

**Phase 1 (Highest Impact):**
1. Daily pulse check (Score: 9)
2. Team workload dashboard (Score: 9)

**Phase 2 (High Impact):**
3. Recognition system (Score: 7)

**Phase 3 (Lower Impact):**
4. Meeting summaries (Score: 4)
5. Async video updates (Score: 4)

## Why This Works

### It's Strategic

Every score connects to:
- A prioritized driving force
- A prioritized target group
- A business goal

**Not arbitrary - traceable to strategy**

### It's Objective

**Traditional:** "I think Feature A is more important"  
**Feature Impact:** "Feature A scores 9, Feature B scores 4"

**Data beats opinions**

### It's Defensible

When stakeholders ask "Why aren't we building X?"

**You can show:**
- Here's our Trigger Map
- Here are our top drivers
- Here's how features score against them
- Feature X scores lower than our current roadmap

**Strategic reasoning, not politics**

### It's Flexible

**When priorities change:**
- Update driver rankings
- Re-score features
- New roadmap emerges

**Strategy drives features, not the reverse**

---

## Scoring Guidelines

### For Negative Drivers (Fears/Frustrations)

**Ask:** "Does this feature help users avoid this pain?"

**High score (3):**
- Directly prevents the feared outcome
- Provides early warning system
- Creates safety net

**Example:**
- Driver: "Fear of team burnout without noticing"
- Feature: "Daily pulse check with burnout indicators"
- Score: 3 (directly addresses the fear)

### For Positive Drivers (Goals/Benefits)

**Ask:** "Does this feature help users achieve this goal?"

**High score (3):**
- Directly enables the desired outcome
- Makes the goal achievable
- Provides clear progress toward goal

**Example:**
- Driver: "Want to demonstrate effective leadership"
- Feature: "Team health dashboard with actionable insights"
- Score: 2 (provides data to demonstrate leadership)

### When in Doubt

**Be honest:**
- Don't inflate scores to justify pet features
- 0 is okay - not everything addresses everything
- Challenge yourself: "Does this REALLY address this driver?"

**Saga will help:**
- "How specifically does this address the fear?"
- "What about this feature reduces that pain?"
- "Is this a 2 or a 3? What's the difference?"

## Common Patterns

### Pattern 1: High Scores Across Multiple Drivers

**What it means:** This feature has high leverage - it addresses multiple psychological needs

**Example:**
- Daily pulse check scores high on burnout fear, leadership goals, and retention fear
- **Action:** Prioritize this - it's strategically valuable

### Pattern 2: High Score on Top Driver Only

**What it means:** Laser-focused solution for most important need

**Example:**
- Workload balancing tool scores 3 on burnout fear, low on others
- **Action:** Still high priority if that driver is #1

### Pattern 3: Moderate Scores Across Many Drivers

**What it means:** Nice-to-have that helps a bit with everything

**Example:**
- Team chat feature scores 1-2 on multiple drivers
- **Action:** Lower priority - not solving urgent problems

### Pattern 4: Low Scores Everywhere

**What it means:** Feature doesn't connect to strategy

**Example:**
- Fancy animations score 0-1 across all drivers
- **Action:** Cut it or deprioritize significantly

## Beyond the Numbers

### The Conversation Matters

The real value isn't just the scores - it's the strategic conversation:

**Questions that emerge:**
- "Why doesn't this feature score higher?"
- "Could we modify it to address more drivers?"
- "Are we missing a feature that would score higher?"
- "Do these scores match our intuition? If not, why?"

**Insights from discussion:**
- Features can be refined to increase impact
- Missing features can be identified
- Assumptions can be challenged
- Strategy can be sharpened

### Combining with Other Factors

Feature Impact is strategic value. You should also consider:

**Feasibility:**
- How hard is this to build?
- Do we have the resources?
- What's the technical risk?

**Dependencies:**
- Does this require other features first?
- Does this enable other features?

**Market timing:**
- Is this urgent for competitive reasons?
- Is there a window of opportunity?

**Combined prioritization:**
```
Priority = (Strategic Impact × Feasibility) + Urgency Bonus
```

## Using the Scored Feature List

### For Roadmap Planning

**Phase 1:** Top-scoring features (typically 8-10 range)  
**Phase 2:** High-scoring features (typically 6-7 range)  
**Phase 3:** Medium-scoring features (typically 4-5 range)  
**Backlog:** Low-scoring features (typically 0-3 range)

### For Stakeholder Communication

**When presenting roadmap:**
1. Show the Trigger Map
2. Show the scoring matrix
3. Show the prioritized list
4. Explain the strategic reasoning

**Stakeholders appreciate:**
- Clear methodology
- Traceable decisions
- Strategic foundation
- Data-driven approach

### For Design Decisions

**During design:**
- Reference the scores
- Focus on high-impact features first
- Ensure design addresses the drivers
- Validate against the scoring

**Example:**
"We're designing the pulse check (score: 9). It needs to address burnout fear, so let's include early warning indicators and actionable suggestions."

## Updating Scores

### When to Re-Score

**Re-score when:**
- ✅ New user research changes driver priorities
- ✅ Business goals shift
- ✅ You learn features don't work as expected
- ✅ Quarterly strategy reviews

**Don't re-score when:**
- ❌ Stakeholder has new pet feature
- ❌ Competitor launches something
- ❌ Minor tactical changes
- ❌ Every sprint planning meeting

### The Living Roadmap

**The scored feature list should:**
- Be updated quarterly (or when strategy shifts)
- Be referenced in every sprint planning
- Guide all feature discussions
- Evolve with your understanding

```
Workshop 1: Business Goals
    ↓
Workshop 2: Target Groups (prioritized)
    ↓
