2.2.2.5 Systems Operation and Support
The support phase
is
the
last phase of the SDLC
whose objective
is to
keep the system running productively during the years following its
initial
installation.
There
are
three
major
activities
that
occur
during
this phase:
Maintain the system
Enhance the system
Support the users
Because
of
the complexity of software and the impossibility of testing
every possible combination of processing requirements, there will
always be conditions that have not been fully tested and thus are
subject to errors. Key tasks in maintaining the system include both
fixing errors also known fixing bugs and making minor adjustments to
processing requirements. To implement major enhancement, the
company must approve and initiate an upgrade development project.
Another
important
activity
is
to
provide
assistance
to
the
system
users.
A help desk consisting of knowledgeable technicians is a popular
method to answer users’ questions quickly and help increase their
productivity.
