The objectives of Service Management
The primary objective of Service Management is to ensure that the IT Services are aligned to the business needs. It is imperative that the IT Services underpin the business processes but it is also increasingly important that IT should act as an agent for Change to facilitate business transformation.

Most organisations that use IT will be dependent on it. If IT processes are not implemented, managed and supported in the appropriate way, the business will probably suffer unacceptable degradation in terms of loss of productive hours, higher costs, loss of revenue or perhaps even business failure, depending upon the criticality of the IT service to the business.
IT service provision, in all organisations, needs to be matched to current and rapidly changing business demands. The objective is to continually improve the quality of service, aligned to the business requirements, cost-effectively. To meet this objective, three areas need to be considered:
- People with the right skills, appropriate training and the right service culture
- Effective and efficient Service Management processes
- Good IT Infrastructure in terms of tools and technology.
These three areas will only facilitate the implementation or realisation of the objectives if they are considered in relation to a conscious, structured mechanism of alignment or 'steering' towards concrete business focused goals. Unless People, Processes and Technology are considered and implemented appropriately within a steering framework, the objectives of Service Management will not be realised.

Change the size of and Defrag Win XP's Virtual Memory (Page File)
Two very important things you need to know: You will need to physically disconnect from the Internet while doing this and you must turn off ALL other programs that are running in the background.
First, let's Defrag the Page File. Make sure you have enough physical memory before attempting this Tweak! It can be done with 512MB RAM, but 1GB RAM is better.
Hold down the WinKey* and hit Pause|Break to open the System Properties - Advanced - Performance - Settings - Advanced - Virtual Memory - Change - select the proper Drive - No paging file - Set - OK your way out while OKing any warnings.
Reboot and now Defrag the HDD. Click Start - Administrative Tools - Computer Management - When that opens, on the Leftt Side click Disk Defragmenter - stretch this window larger so you can see all of the Hard Drives/Partitions - click on the Hard Drive/Partition you need to Defrag and click Defragment. When it finishes, click OK and Reboot once again.
Now let's re-enable the Page File and change the Page File size - Hold down the WinKey* and hit Pause|Break to open the System Properties - Advanced - Performance - Settings - Advanced - Virtual Memory - Change - select the proper Drive - Custom Size - set both Initial and Maximum to twice the size of physical memory you currently have installed (...meaning, if you have 512MB RAM, set both to 1024MB...If you have 1GB RAM, set both to 2048MB...) - Set - OK your way out while OKing any warnings. Reboot one last time.
Now the Page File will be Defragged and in one contiguous file.
* The WinKey is the Windows Flying Logo key between the CTRL and ALT keys.
Change the Internet Explorer Window Title
- Start - Run - type regedit.exe - Enter - then navigate to - HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\Window Title - and set it to blank. If this key is not present, add a String value and name it Window Title and modify the value, leaving the value blank.
Increasing shutdown speed by reducing wait times part 1
Change the HungAppTimeout and/or WaitToKillAppTimeout Values - 95.
Open REGEDIT and navigate to 'HKEY_CURRENT_USER\Control Panel\Desktop\'
Highlight the 'WaitToKillAppTimeout' value.
Set it to '1000' (the default should be 20000).
Now highlight the 'HungAppTimeout' value
Set it to '1000' also.
Please notice that tip #96. Increasing shutdown speed by reducing wait times part 2 on the same page gives instructions for changing the same settings, but for All Users of the computer.

ITIL --- Information Technology Infrastructure Library
ITIL is the most widely accepted approach to IT service management in the world. ITIL provides a cohesive set of best practice, drawn from the public and private sectors internationally. It is supported by a comprehensive qualifications scheme, accredited training organisations, and implementation and assessment tools.
History
Responding to growing dependence on IT, the UK Government's Central Computer and Telecommunications Agency in the 1980s developed a set of recommendations. It recognised that without standard practices, government agencies and private sector contracts were independently creating their own IT management practices.
The IT Infrastructure Library originated as a collection of books, each covering a specific practice within IT Service Management. ITIL was built around a process-model based view of controlling and managing operations often credited to W. Edwards Deming and his plan-do-check-act (PDCA) cycle.[1]
After the initial publication in 1989–1996, the number of books quickly grew within ITIL v1 to over 30 volumes.
In 2000/2001, to make ITIL more accessible (and affordable), ITIL v2 consolidated the publications into 8 logical "sets" that grouped related process-guidelines to match different aspects of IT management, applications, and services. However, the main focus was known as the Service Management sets (Service Support and Service Delivery) which were by far the most widely used, circulated, and understood of ITIL v2 publications.

- In April 2001 the CCTA was merged into the Office of Government Commerce (OGC), an office of the UK Treasury.
- In 2006, the ITIL v2 glossary was published.
- In May 2007, this organization issued the version 3 of ITIL (also known as the ITIL Refresh Project) consisting of 26 processes and functions, now grouped under only 5 volumes, arranged around the concept of Service lifecycle structure.
- In 2009, the OGC officially announced that ITIL v2 would be withdrawn and launched a major consultation as per how to proceed.
