We've been providing consulting services about ChangeMan ZMF (CMN/ZMF) for over 2 decades now. It keeps being fun to see how each CMN/ZMF customer always has some type of unique requirements, special customizations, etc. Not to speak about all the challenges that come with each release upgrade of CMN/ZMF (I started on release 3.2.1b in 1990, recently I was involved in an upgrade to the latest and greatest 7.1.x release).
