d. Methods
and
procedures
test.
During
conversion,
the
methods
and
procedure
for
the
new
system
will
be
put
to
their
fist
real
test.
Methods
and procedures
may
have to be
modified
if
they prove to be awkward and
inefficient from the end-users’ standpoint.
e. Backup and recovery testing.
All backup and recovery procedures
should
be tested. This should include simulating data loss disaster and testing the
time
required
to
recover
from
that
disaster. Also, a before-and-after
comparison of the data should be performed to ensure that data was
properly
recovered.
It
is
crucial
to
test
procedures.
Don’t
wait
until
the
first disaster to find an error in the recovery procedures.
3. Audit
testing
certifies
that
the
system
is
free
of
errors
and
is
ready
to
be
placed
into operation. Not all organizations require an audit. But many firms have an
independent audit or quality assurance staff that must certify a system’s
acceptability and documentation before
that
system
is
placed
into
final
operation.
There are independent companies that perform systems and software certification
for end-users’ organization.
2.1.8 Questionnaires

any
kind
of
information about new system, requirements, and so forth from respondents.
