• Specific disaster preparedness training for new team members is defined and im-
plemented.
• The team has regular disaster preparedness exercises.
• The exercises include fire drills performed on the live service.
• After every disaster, a postmortem report is produced and circulated.
Level 4: Managed
• The SLA is tracked using dashboards.
• The timing for every step in the process from the moment the event occurred is
tracked on the dashboard.
• A program for disaster preparedness training ensures that all aspects are covered.
• The disaster preparedness program measures the results of disaster preparedness
training.
• As teams become better at handling disasters, the training expands to cover more
complex scenarios.
• Teams are involved in cross-functional fire drills that involve multiple teams and
services.
• Dates for publishing initial and final postmortem reports are tracked and measured
against the SLA.
Level 5: Optimizing
• Areas for improvement are identified from the dashboards.
• New techniques and processes are tested and the results measured and used for fur-
ther decision making.
• Automated systems ensure that every failure mode is exercised within a certain
period, by artificially causing a failure if one has not occurred naturally.
