Basic CASS Process
CASS is a risk-based, closed-loop system, 4 basic processes:
(1) Surveillance.
An information gathering/audit process you use to collect data to
measure your program execution and measure your program results.
(2) Analysis.
An analysis process you use to identify any maintenance program
deficiencies and any necessary corrective actions.
(3) Corrective Action.
A planning process you use to ensure that your corrective actions and
implementation steps are well-defined.
(4) Follow up.
A follow up, performance measurement process you use to verify that
your corrective actions are performed and are effective. This is also
an information-gathering and analysis process, thereby, closing the
loop.
