If you spend anytime at all doing interface design work you know the value-added from wireframes early on in the development process. It helps to point the customer to what’s important in the early-going, namely, labels, location of content, navigation, etc while not worrying about the font or what color the background is going to be. It’s this stage that information architects flex their muscles.
I have created a wireframe for MOSS 2007. It is based on the master page that comes out-of-the-box with SharePoint 2007. If you want to make it WSS-specific, all you really have to do is remove the “My Site” and “My Links” in the top-right navigation bar.
The two formats available are a Visio template (.vst) and a PDF. I made use of the GUUUI Visio stencil kit in Visio 2007, but it should open fine in 2003. If you don’t have Visio you can use the PDF.
