+# Tone of Voice Example: SaaS Onboarding Tool
+
+**Context:** B2B SaaS for employee onboarding, target users are HR managers (stressed, overwhelmed, want to feel capable)
+
+---
+
+## Suggested Tone of Voice
+
+### Tone Attributes
+
+1. **Supportive & Reassuring**: HR managers are stressed about onboarding. Our tone should reduce anxiety, not add to it.
+2. **Professional but Warm**: B2B context requires professionalism, but warmth builds trust.
+3. **Clear & Concise**: Busy users need straightforward communication, no fluff.
+4. **Empowering**: Frame actions around user capability, not system features.
+
+### Examples
+
+**Error Message:**
+- ✅ "We couldn't find that email. Double-check for typos?"
+- ❌ "Error 404: User not found"
+
+**Button Text:**
+- ✅ "Add your first employee"
+- ❌ "Create new record"
+
+**Empty State:**
+- ✅ "Your onboarding dashboard is ready. Let's add your first employee to get started."
+- ❌ "No employees added yet"
+
+**Success Message:**
+- ✅ "Perfect! Sarah's onboarding is set up. We'll send her the welcome email tomorrow at 9 AM."
+- ❌ "Employee record created successfully"
+
+---
+
+## Analysis
+
+**Why This Tone Works:**
+- **Supportive**: "We couldn't find" (collaborative) vs "Error" (blaming)
+- **Professional but Warm**: Uses proper grammar but friendly language
+- **Clear**: Specific, actionable messages without jargon
+- **Empowering**: "Add your first employee" (user action) vs "Create new record" (system function)
+
+**Alignment with User State:**
+- HR managers are stressed → Reassuring tone reduces anxiety
+- Want to feel capable → Empowering language focuses on their actions
+- Need efficiency → Clear, concise messaging respects their time
+- Professional context → Maintains appropriate formality with warmth
