I saw this page on the ETL integrator wiki & thought it was a great template to use when doing an initial write-up for a project. See: http://wiki.open-esb.java.net/Wiki.jsp?page=ETLSEOnePager
I might try to use something similar for my next side project. Perhaps w/ some enhancements it could even be used as the template for presenting a project to a architecture review board @ work.
