Mike I conduct training courses for a couple providers....one of them I would call a major global one and my recommendation is this:
An EMS-LA course would be OK and you would get some good info out of it, but unless you're going to do auditing all the time and 3rd party registration stuff save your money. You would be better served taking a 2 -3 day implementation course and an Internal Auditor course.
I'll be more than honest with the next. You already know at least 75% of what you need to know if you are trained and experienced with 9K2K. What is happening to you happens to everybody, your getting wrapped around the axle because of the word "ENVIRONMENTAL". Take that word and round file it. Focus on the term "management system". What you are going to do is implement a "management system" that is going to be centered around just another 1 of your organizations core processes. That's all!! This is a portion of my approach when I conduct training courses.
When you implement your system, do it in such a way as it is transparent within the organization....it's not a special way we do business, it's just the way that we do conduct business.
