ABSTRACT
This chapter discusses the need for controlling changes in the data center and provides recommendations for implementing change control and problem tracking systems. The change control process beings when the treated enhancement is to be incorporated into the production environment. A formal change control system—which identifies, evaluates, and coordinates required changes—can minimize such performance problems. The change control process comprises a series of steps aimed at providing the user with maximum system stability and availability. These steps are initiation, review, approval, scheduling, coordination, implementation, and follow-up audit. The reporting function is a key component of the change control process. For effective performance of this function, a change history file and some automated control over change-related data are necessary. The implementation of the change control process should be followed by the development and implementation of a problem tracking system. Change control and problem tracking are logically linked and are needed for effective data center management.
