Lesson I ntroduction
Welcome
to
the Reliability
Acti
vities and Analysis lesson!
After
a system and
its
components are assessed
for
their reliability, how
should the program go
about
improving the reliability?
There are eight methods programs can use
to
improve a system's
reliability and the
parts
used based on previous reliability analysis results.
Each method addresses
different
unique
factors
and inputs w
ith
regard
to
system design.
Upon completion
of
this lesson, you will be able
to
identify
reliability
acti
vities.
