Technical Management Practices
Technical management practices have been adapted from technology management domains for service management purposes by expanding or shifting their focus from a technology solution to an IT service. Under ITIL 4, there are only three technical management practices: deployment management, infrastructure and platform management, and software development and management practices. For the exam, only the deployment management practice is testable and it's only examinable at the recall level. But each practice under this category will still be discussed briefly for your understanding.
The purpose of the Deployment Management practice is to move new or changed hardware, software, documentation, processes, or other components to the live environment. It may also be involved with deploying components to other environments for testing or staging. Basically, release and deployment used to be one practice but in ITIL 4, release and deployment are now two different things. Release is more focused on the approval process, while deployment is more about moving the change over to the live environment. So that's what you're going to focus on inside deployment management. As you build a new server or build a new capability, it's going to go through the change process, get approval, go through the release management process, and eventually, it will get deployed through deployment management and move itself from transition into the deliver and support perspective.
Infrastructure and platform management is a technical management practice you do not need to know for the exam. But is covered so you at least have heard about it, and you'll understand it a little bit if somebody asks you about it. Infrastructure and platform management is responsible for overseeing the infrastructure and the platforms that are used by the organization. It enables the monitoring of the technology solutions that are available, including solutions from third parties. When you think about the platform or the infrastructure, think about the servers, software, network, all of that stuff. The people who are monitoring it to make sure it's up and working properly, is also part of infrastructure and platform management. This tends to be a very technical domain, and it's one that's covered by technical personnel who are responsible to make sure the systems are up-and-running at all times. Normally, this is people inside your network operations center or your security operations center.
The third technical management practice is software development and management. Like infrastructure and platform management, this one is not covered by the exam. But you need to know on a superficial level that the software development and management practice is responsible for ensuring that applications meet stakeholder needs in terms of their functionality, reliability, maintainability, compliance, and auditability. So, whether you're developing it in-house or deploying other people's software into your environment, it's going to be handled through this practice. You're going to make sure that software meets your functionality, reliability, maintainability, compliance, and auditability needs. But you're not going to be the one who's going to push that out into the environment. That's going to happen through release and deployment management. But you're going to make sure to track it all along the way and you know what applications that are out there are meeting your stakeholders' needs.
