+# Kickoff Patterns
+
+## Adaptive Kickoff Tone
+
+Default to a practical and energizing kickoff: clear enough to start work immediately, positive enough to create momentum, and grounded enough to avoid hype.
+
+Choose the tone that fits the audience and project risk:
+
+- **Practical/direct:** Best for internal teams, operational work, and projects where speed and clarity matter most.
+- **Motivational/energizing:** Best for launches, creative work, and moments where the team needs shared momentum.
+- **Calm/reassuring:** Best for complex, delayed, sensitive, or high-risk projects where confidence and steadiness matter.
+- **Formal/client-safe:** Best for external stakeholders, executive audiences, regulated work, or contractual delivery.
+- **German business casual:** Best for German-language teams that need professional clarity with a friendly, collaborative tone.
+
+## Kickoff Structure
+
+Use this structure for a kickoff message or kickoff document:
+
+1. **Why this matters:** Explain the reason for the project and the value of doing it now.
+2. **Goal:** State the main outcome in one clear sentence.
+3. **Success criteria:** List the conditions that will make the project successful.
+4. **Timeline:** Give key dates, milestones, and near-term expectations.
+5. **Roles:** Name the DRI, named owners, reviewers, approvers, and any role placeholders that still need staffing.
+6. **Basecamp usage:** Explain where To-dos, messages, docs, schedules, and files should go.
+7. **First actions:** List the first concrete steps and owners.
+8. **Status update pattern:** State when updates happen, where they are posted, and what format they should follow.
+9. **Invitation for questions:** Make it easy to raise questions, risks, gaps, and decisions needed.
+
+## Project Brief Rule
+
+Use a kickoff message only for small projects with low ambiguity, few stakeholders, and limited risk.
+
+Create a Project Brief for medium, complex, external, or high-risk projects. The brief should carry the durable project context, while the kickoff points people to the brief and highlights the immediate next actions.
+
+## German `Vorlagen` Adaptation
+
+When adapting kickoff patterns for German `Vorlagen`:
+
+- Preserve the original structure and intent.
+- Write naturally in the target language.
+- Adapt examples, formality, and phrasing to the audience instead of translating mechanically.
+- Keep Basecamp usage instructions practical and explicit.
+- Use German business casual tone unless the stakeholder context calls for more formality.
