Welcome to The Cove Dimkey!
What a job you have chosen for yourself. The nature of your question makes me wonder if you are prepared to address the nature of the work you are considering.
In the movie Memoirs of a Geisha, there is a line that fits: "It is useless to push a cart sideways." For your question I will apply the quote in this manner:
I do not know anyone who can "get" a small or medium sized company to embrace quality management or other stuff. People will embrace a discipline when they are motivated to do so--and there are many threads to read (try a search in the toolbar above, using the key words "management commitment") that may help you understand what I mean.
