CM tools, and CMDBs, tend to be large and expensive. They also tend to embed workflows, that, for better or worse, tell you how to do your job. They are also a bit like insurance, in that they cost a lot and you only get the benefit in an incident.
CM is an approach that depends entirely on the organisational size and culture.
Any real-world examples of CM success in small, medim and large organisations? Which tools? Costs? Timescales?
