Here is a great presentation about working with stakeholders in an organized way, with great tools for analysis, planning of a strategy on how to approach them, plenty of tools for going through all steps.

There is actually one big lesson - the planning of our approach to stakeholders can be the most important thing in any initiative. If you read the whole thing, you may also find a bit alternative way to describe the different levels of participation, namely:

- Manipulation
- Information Provision
- Consultation
- Participation
- Delegated Power
- Citizen Control

I like quite a lot the final one. Highly recommended material!
