About the only thing I liked about this was the fact that the problem of change management is recognised. Within this "Process" there is so much room for error, that within any environment other than the simplest - you would still have problems.
I live and breathe change management for databases, if you're interested in reading what I live by drop me an email and I'll send you an article which I think does this subject justice.
