Final answer:
The deployment management practice is aimed at moving various types of new or changed components into live environments in a controlled and repeatable manner, minimizing deployment-related errors and ensuring that they meet design and testing requirements.
Step-by-step explanation:
The purpose of the deployment management practice is to move new or changed components into live environments. This includes a variety of changes such as hardware, software, documentation, and processes. Effective deployment management ensures that these components are released into the live environment in a controlled, efficient, and repeatable manner. It aims to minimize the impact of deployment-related errors on the live environment and to make sure that the new or changed services meet the requirements that were set out in their design and testing phases.
