This is the FAP SIG Handbook, it may be useful as a template/example for other SIG's wishing to develop something similar.
(Note from ACBS staff... the example below is a terrific guiding document for a SIG. Please know however that it is ok for a SIG to take a less formal approach to it's governance depending on it's goals. For example, "co-chairs" might be all you need to run your SIG, instead of a formal Board. While this document is fabulous, we didn't want it to scare anyone. :)
