Just what exactly does an IT Manager do? Hmm manages the infrastructure, applications eg ERP, network, budget, technology planning, talk to the users and much more.
I have always wondered about this. After quite a bit of Googling, and library crawling, the answer to the question is IT Service Management. Or described in the series of books of IT Infrastructure Library.
ITIL, there are 7 main modules, described in 2 books
Service Delivery
Financial Management, Capacity Management, Service Continuity Management, Availability Management
Service Support
Service Desk, Incident Management, Problem Management, Configuration Management, Change Management, Release Management
Note the daily operational issues are captured not in Configuration Management but in another module called ICT Infrastructure Management. Applications in yet another module on Application Management. Configuration Management here is much more tuned towards a higher level of parts of Asset Management.
