One of my colleagues sent me a couple good articles on SharePoint Governance specifically related to manufacturing companies.

Some good insights and we would agree with most of the suggestions in these articles.  I especially like this comment:

Because SharePoint is relatively easy to install departmentally, companies face a Wild West situation that calls for a solid governance strategy, according to Info-Tech, which provides its clients with SharePoint deployment tools and advice. It strongly warns companies to view SharePoint not as a file system, but as a content database, which makes features and management “exponentially more complex” and difficult to alter once the software is set up. Without governance, SharePoint systems become harder to manage over time, which makes a positive return on investment virtually impossible to achieve, according to Info-Tech.
