CMS Watch recently released a new training program. Their Fundamentals of Enterprise Content Management Technology aims to help educate organizations on ECM technologies. The course has a broad focus from what "you're getting into" when implementing ECM technologies to how gather requirements (and a lot in between). Even if you are working with or plan to work with a consulting agency, it will greatly benefit your organization to be educated.
From experience, educated clients are in a better position to make decisions about implementations than clients that have limited experience and/or education. If you're considering implementing ECM technologies, I would highly recommend attending the course.
