No CI is

- Added - Modified - Replaced - Removed

without appropriate

controlling

documentation

Control

(28)

1. The introduction to CM

• To verify the physical existence of CIs

• To check that they are correctly recorded in the CMDB

CMDB = Configuration Management Database

3. Should we care ?

With no or with not a reliable Configuration

Management implemented, this can happen:
