EXAM - Definition of Release Unit
Which of these is the BEST description of a release unit?
A. The portion of a service or IT infrastructure that is normally released together
B. The smallest part of a service or IT infrastructure that can be independently changed
C. The portion of a service or IT infrastructure that is changed by a particular release
D. A metric for measuring the effectiveness of the Release and Deployment Management process
---------------
Answer: A
Just as change management begins with defining which activities will require a change record, release management begins with documenting which components will be released simultaneously.
ITIL defines a release unit as the set of components that get upgraded, installed, or changed all at the same time.
As a simple example, often the next version of a business application requires new versions of middleware software products. This means that the application and the middleware form a release unit, because they are deployed at the same time.
Why ITIL scares IT managers?
According to the great article at the Network World (http://www.networkworld.com) there are several reasons why your organisation may resist implementation of ITIL.
To directly quote the article:
"The resistance comes from fear, according to ITIL experts and industry watchers, who argue that education around ITIL, its potential benefits and challenges would help implementations get off the ground more quickly. For one, the premise of re-aligning IT operations around standard processes intimidates most non-believers, and the recent updates to the framework, ITIL Version 3, is causing confusion among many IT managers that started adopting ITIL Version 2.
To help address fears and reduce confusion, ITIL expert and author Linh Ho compiled a list of the most common fears she encounters in customer environments and detailed some ways to keep the anxiety around ITIL at bay. Ho, product marketing manager at Compuware, also served as a reviewer on the ITIL V3 foundation books and is co-author of the itSMF's Six Sigma for IT Management book. Ho also worked for business service management vendor Proxima Technology before it was acquired by Compuware earlier this year. She says that the industry is working toward reducing the confusion around ITIL.
"We are often on the front lines talking to customers and find that there is a lot of fear and confusion out there today," Ho says. "We are working to demystify and help abate fears." "
Here are couple of things you might encounter when you try to implement ITIL in your organisation:
