Which of the following methods is a means of ensuring that system changes are approved before
being implemented, only the proposed and approved changes are implemented, and the
implementation is complete and accurate?

A.
Configuration control

B.
Documentation control

C.
Configuration identification

D.
Configuration auditing

Explanation:
Documentation control is a method of ensuring that system changes should be

agreed upon before being implemented, only the proposed and approved changes are
implemented, and the implementation is complete and accurate. Documentation control is involved
in the strict events for proposing, monitoring, and approving system changes and their
implementation. It helps the change process by supporting the person who synchronizes the
analytical task, approves system changes, reviews the implementation of changes, and oversees
quality assurance element of configuration management. It is occupied in the process of periodic
checks to establish the consistency and completeness of accounting information and to validate
that all configuration management policies are being followed. Configuration audits are broken into
functional and physical configuration audits. They occur either at delivery or at the moment of
effecting the change. A functional configuration audit ensures that functional and performance
attributes of a configuration item are achieved, while a physical configuration audit ensures that a
configuration item is installed in accordance with the requirements of its detailed design
management. Configuration control is a set of processes and approval stages required to change
a configuration item’s attributes and to re-baseline them. It supports the change of the functional
and physical attributes of software at various points in time, and performs systematic control of
process of identifying the attributes that define every aspect of a configuration item. A
configuration item is a product (hardware and/or software) that has an end-user purpose. These
attributes are recorded in configuration documentation and baselined. Baselining an attribute
forces formal configuration change control processes to be effected in the event that these
attributes are changed.
