Daman,
We started changing our system to process maps about two years ago and went through the pain and fog which no doubt your going through.
Now we have gone through our TS audit my schedule is settling down a little, if you would like to see how we approached the change you are welcome to visit us in the next week or so.
We're on ly a couple of hours up the motorway, give me a call. My number / email is on my user profile.
