In contrast to the level 3 Unit 20852, Install and maintain basic information and
communications technology (ICT) systems and services, where trainees primarily
work with, and have responsibility for, the items of infrastructure and equipment in
their immediate vicinity, and under direct supervision, this level 4 unit standard is
concerned with the ability to encompass larger, more complex entities or systems.
For this unit standard, the individual components may be separated by some
distance; basic network and system design is called for; testing will include system or
end-to-end tests; the work is without direct supervision; there may be supervision of
others and responsibility for their work. Ability to work with this larger focus is a
critical aspect of assessment against this unit standard.
