SharePoint Customisation Policy 2007 White Paper
The recently released SharePoint Products and Technologies Customization Policy 2007 White Paper provides a great starting point for implementing and managing customisations in a SharePoint based environment. The paper contains a list of customisations that are possible with WSS 3.0 and MOSS 2007 and provides guidance on how and when to use each type of customisation. It also contains information on what is and isn’t supported.
