go to the BPM.com and then Resources

first of all, every business has its process that suit with its contemporary situation. any way if you seek for some pattern i also recommend you to take look at hand books and other similar organisation documentation in your interest field. by the way some BPM software have pre designed process library that, if you can access one, are good touch.

Thanks Ali and Akbar!
