The friendly people over at Collaboris shared an infographic on SharePoint settings by level.

They released (as a newyears gift I suppose) this really nice chart that shows you all the settings you can make at each level:

- farm

- web application zone

- web application

- site collection

- site

This is crucial if you want to take a practical look on your SharePoint Governance. Take this reference chart in your Governance meetings and you have an immediate overview of what you need to talk about regarding the SharePoint settings.
