This is a bit old Maya tutorial on character pipeline (2003), but still quite unique and there are few of them on this topic. Originally sold as DVD by Autodesk (with video presentation at Siggraph Maya Master Class), but for long time it`s not available.
Advanced Character Pipeline and Tools
I happened to find this online. So if you want to learn about this and setting up your first animation pipeline, it`s worth having a look at this.
