Impact of an IT Service Disruption
During an IT service disruption, one in which the continuity plans are activated, unless regularly reviewed and tested, it is likely that the plans will not be current or contain a sufficient quantity of gaps in processes and procedures to inhibit their usefulness when implemented.
It is for this reason that the Business Continuity Plan, the Business Process Continuity Plans, the IT Service Continuity (Disaster Recovery) Plans and the Recovery Validation Procedures need to be clearly documented, integrated and regularly tested to ensure their currency with today?s business operations.
A major or catastrophic IT services disruption will require the activation of one or more ITSC/DR Plans. And, it will mandate the activation of the Business Process Continuity plans, aspects of the Business Continuity Plan and potentially the organisational Crisis Management plan. Continuity documents need to be effectively and accurately integrated, covering all aspects of continuity from time of incident, through Plan activations, data resynchronisation and/or reconstruction, and the eventual resumption of business processing.
In contrast to the traditional DR approach of planning solely for the least probable scenario involving a total loss of the data centre, other resiliency strategies such as high-availability and active-active implementations, disaster tolerant systems, and pseudo-real time data replication across multiple sites are becoming more prevalent in the delivery of IT Service Continuity.
As each new strategy and solution is implemented, the need for integrated continuity planning increases ? as does regular testing that the plans continue to maintain their currency with the solutions deployed.
