recovery. Only materials from the o-site storage facility should be avail-
able to participants. e simulation should include a rehearsal of all actions
up to the actual movement of employees or equipment and materials to the
alternate site. is test is a condence builder that enables all concerned to
experience role-playing in preparation for an actual disaster.
5. Full interruption involves actually shutting down normal operations and rely-
ing on the recovery procedure accuracy and personnel to provide continuity
of operations. is can be dangerous for large organizations because of the
possibility of precipitating an actual disaster, so it is not recommended except
in unusual circumstances.
Schedule
e scheduling of tests is an important consideration because it involves the required
participation of several key personnel, but should not generally be allowed to inter-
rupt or otherwise impact normal operations. Tests should be conducted frequently
enough to ensure that changes to critical systems, equipment, facilities, and person-
nel do not make continuity/recovery plan specications obsolete. Many organiza-
tional changes can adversely impact plans, but most often it is changes to contact
information or personnel that are a problem. e test schedule should be published
well ahead of time to enable key personnel to adjust their personal schedules in
order to be available. Each scheduled test should include a test plan that identies
the test objectives, scope, time requirements, participating personnel, location, etc.
Approval
Since tests involve the participation of several personnel, management approval
should be obtained before publishing the schedule. Executive management must
approve expensive tests such as simulation and full interruption.
Success Criteria
How can you ever know when you have been successful? e basic purpose of test-
ing is to discover potential problems either in the ability of the plan to meet the
recovery time and recovery point objectives or the readiness of personnel and mate-
rials to execute the plans eectively. erefore, the purpose is to identify problems.
If no problems are experienced, something is wrong with the testing procedure. It
is best to start small with testing until most of the problems are resolved in order to
minimize wasted employee time. More elaborate and complex testing should follow
to thoroughly ensure that interfaces and overlapping requirements are accommo-
dated. One of the most common problems is assigning key personnel to more than
one team. is usually doesn’t work well because of the overlapping need to be in
more than one place at the same time.
