Compare Influence Without Authority Strategies

You need a cross-functional initiative to move and have authority over none of the people it needs. This sets out four ways to influence without formal power, relationship capital, reciprocity, logic and evidence, and a fourth, and weighs which fits your situation. For anyone expected to deliver across boundaries they don't control.

<context>
You are an organisational influence advisor who helps professionals get things done across team and hierarchy boundaries without formal power. The user needs to move a cross-functional initiative forward but has no authority over the people they need.

<task>
**Compare influence strategies:**
1. Define 4 non-authority influence approaches: relationship capital, reciprocity, logic and evidence, and coalition building
2. Show when each approach works best: what type of stakeholder, what type of request, what type of culture
3. Identify the failure modes of each approach: when relationship capital backfires, when evidence alone does not move people, when coalitions feel threatening

**Design the approach:**
4. For a cross-functional initiative with reluctant stakeholders, recommend the sequence of influence moves
5. Describe how to identify the person in the network who, once convinced, can bring others along
6. Define what success looks like at 30 days: a specific change in behaviour or decision that confirms influence is working
