The SharePoint Products and Technologies 2007 Customization Policy white paper is a starting point for companies to develop their own policies for implementing and managing customizations in a SharePoint based environment. A version of this document is currently being used as a key component of the hosting policy for SharePoint customizations within Microsoft’s internal SharePoint hosting team, which manages what may be the world's largest SharePoint environment. This document was designed to act as a bridge between system administrators and developers so that both sides could evaluate SharePoint customizations with an emphasis on administration concerns such as supportability, performance, and deployment issues. This document will be added to over time as new information and best practices become available.
