Learning aim A: Examine the IT system support and management needs and
characteristics of different organisations, which are essential to
their operation
A1 Purpose and nature of IT system support and management
The concepts and purpose of IT system support and management.
•
The main purpose of IT system support and management is to:
o
support different types of user using the system, including end users who can
be classified as beginners, intermediate or expert, and administrators who have
access rights that include the support staff
o
provide continuity of IT-based:
–
systems, e.g. servers and virtual personal computers, cloud storage, mobile
devices, laptops, bring your own device (BYOD) and network systems
–
processes, e.g. financial management, email communications and stock control
o
maintain and improve the performance of organisations through system
diagnosis, preventative maintenance and system upgrade and configuration
o
ensure security and protection of data in the system, including storage and
backup and recovery in the event of system failure.
•
The support and management needs of organisations varies across the
system’s life cycle:
o
design, build and test, e.g. install software, configure systems, train and
set up users
o
operate, e.g. password resets, fault logging and management, managing
data storage
o
decommission, e.g. archive and migrate system data, recycle hardware
o
support resources include: human, number and type of software licences,
number and type of hardware devices, capacity requirements, e.g. size of
hard disk drive (HDD) and network
o
demand increases due to organisational change, e.g. changes to processes
and systems
o
user need for support can be frequent or infrequent depending on their usage
of the systems, expertise and access rights
o
support provided is a compromise between cost, the resource availability,
productivity of users and the environmental impact, e.g. energy consumption
and reuse/recycling of hardware
o
organisational needs can vary by sector, e.g. office, process and engineering
industries and entertainment, IT and media sectors.
