### Before Workshop
- [ ] Define service scope
- [ ] Identify key personas
- [ ] Gather existing journey maps
- [ ] Prepare materials (sticky notes, markers, template)

### Workshop Flow

**Part 1: Set Context (30 min)**
1. Review service scope and persona
2. Share existing research/data
3. Align on goals

**Part 2: Customer Journey (45 min)**
1. Map customer actions (sticky notes)
2. Sequence and refine
3. Identify channels at each step

**Part 3: Lines of Interaction (30 min)**
1. Add frontstage actions
2. Draw line of visibility
3. Add backstage actions

**Part 4: Support Systems (30 min)**
1. Identify technology dependencies
2. Map policies and partners
3. Note training needs

**Part 5: Analysis (45 min)**
1. Mark fail points
2. Identify pain points
3. Spot opportunities
4. Add emotional journey
5. Note metrics

**Part 6: Prioritize (30 min)**
1. Vote on priority improvements
2. Assign ownership
3. Define next steps

### Outputs
- [ ] Completed service blueprint
- [ ] Prioritized improvement backlog
- [ ] Action items with owners
