Okay. My learners, we are on less than 5.2 availability management process.
Okay. Are you ready?
I'm sure you're ready. Let's go.
Alright. So, learning objectives in this video, we will cover understanding the availability management process, understanding the basic concepts of availability management as well as the key elements of availability management.
It's a lot of availabilities, huh?
Alright, so let's move on. So we have availability management process. So the purpose is to ensure that the level of availability deliver in all I T services matches that agree availability needs of the business. So rather, it's for current or future through the BRM,
and it has to be a this available needs to be inside of the S l A.
When we're conducting this process. Okay.
All right. So some of the objectives of
availability management. So we look into the availability plans. It tells the service transition how to build, okay, just to get a visual. So it provides the advice and guidance to all other areas of the business in the i t. On the availability related issues.
So ensures that the service of ability achievements meet all their agreed targets
by managing services and resource is related to the availability performance, so it assists with the diagnosis as well as the resolution of the availability related to those incidents and those problems.
Aziz, well as assessing the impact of all the changes that may have happened during that availability plan
and the availability of all the services and resource is okay, So it's definitely ensuring that is being proactive and that the availability of service are implemented wherever it is caused, justifiable to do so
now those are the objectives of the availability management process. Now, when we go into the scope of it now, the scope is basically yes, you know, you have the availability measuring process that covers it covers the design. It covers the implementation. It covers the measurement, the management and the improvement off the I T service and component availability.
So when we take a look at the
look at this more so, the availability management starts as soon as the availability requirements for the I T service are clean enough to be articulated. So once it's started is the ongoing process and is finishing up when the I T services decommission or retired.
so when dealing with our understanding. The availability mentioned process. There's two key concepts, right are two key elements, and those are the reactive activities as well as the proactive activity. Sounds like life, right? We have to be proactive or reactive for either or
eso. Let's get dive into the reactive activities. Right? So
the reactive activity is more of the monitoring and the measuring
and and as well as analyzing the incidents and events as well as problems involving the unavailability, right, So it performs as part of the operational roles within this particular process. Okay.
And then when you look into the proactive activities, it sounds pretty, pretty straightforward, right? So it's where you're planning, right? And you're designing and you having it approved improving the availability of that particular service.
So it's performed as part of the design and the planning rose. When you're conducting this process because you wanna be proactive when things come right, so that's
best practices.
so then we're going to some of the basic concepts of availability management. And when we look into these particular
principles, um, there develop bility. So it involves
Ah, lot of difference. Um,
I t services or other see eye to perform its agree function when it's required. So these are important terms to remember,
and so it gives the ability of I t service or our configuration items to perform its agreed function when it requires. So the availability is determined by the really reliability. The maintain ability serviceability the performance
as well as the security. So availability is usually calculated as a percentage, right? So this calculation
it's often based on the agreed service time and downtime and his best practice to calculate the availability of the i T. Service using those measurements of the business outcome. And then we're going toe reliability. So that measures how long I t service or other configuration items can be performed.
It's agreed upon function without interruption, right? So
when you look into here is usually measure as
the mean the meantime between failures so that MTBE, MTB, f
and the meantime between service incidents, which is the M. T. B s I, and the term can be also used to state how likely it is that a process function etcetera will deliver is required outputs to that business. And then when you go into the maintain ability
ATM or measures
how quickly and effectively that I t service or other sea ice can be restored to normal working after a failure. Now, this is often measure and reported to the mean time to restore service, which is the MTR s. And
it's also used in the context of a software or a I t service development, to maintain the ability to change or repair easily.
And we go into the serviceability where it comes into more of the ability of a third party supplier to meet the terms of his contract. Now, this contract will include agreed levels of availability, the reliability as well as the maintain ability for supporting the service or the component
and the V B F, the business, the vital business function. You could think of it as it ate him.
Okay, Now it is more a part of a business process that is critical to their success of the business. So v. P. V. P s. They are important consideration of the business continuity management so that I t service continuity management and availability management as well.
All right. So in summary, um, in less than five point to recover the availability management process, the purpose of the availability management process, the scope of the availability management as well as the concepts of development, the
the veil ability, management process. I know I get tongue tied with the ability.
It's so many of our abilities. All right. Thank you for your time. We'll go carry on with the quiz and then on to our next lesson. All right, so you then.
