including project scope and planning, business impact analysis, continuity planning, and approval and implementation.
Every organization must have plans and procedures in place to help mitigate the effects a disaster has on continuing operations and to speed the return to normal operations. To determine the risks to your critical business functions that require mitigation, you must work with a cross-functional team to conduct a business impact analysis from both quantitative and qualitative points of view. You must take the appropriate steps in developing a continuity strategy for your organization and know what to do to weather future disasters.
Finally, you must create the documentation required to ensure the effective communication of your plan to present and future BCP team participants. Such documentation should include the continuity of operations plan (COOP). The business continuity plan must also contain statements of importance, priorities, organizational responsibility, and timing. Also, the documentation should include plans for risk assessment, acceptance, and mitigation; a vital records program; emergency-response guidelines; and procedures for maintenance and testing.
Chapter 18 will take this planning to the next step—developing and implementing a disaster recovery plan that includes the technical controls required to keep your business running in the face of a disaster.
Exam Essentials
Understand the four steps of the business continuity planning process. Business continuity planning involves four distinct phases: project scope and planning, business impact analysis, continuity planning, and approval and implementation. Each task contributes to the overall goal of ensuring that business operations continue uninterrupted in the face of an emergency.
Describe how to perform the business organization analysis. In the business organization analysis, the individuals responsible for leading the BCP process determine which departments and individuals have a stake in the business continuity plan. This analysis serves as the foundation for BCP team selection and, after validation by the BCP team, is used to guide the next stages of BCP development.
List the necessary members of the business continuity planning team. The BCP team should contain, at a minimum, representatives from each of the operational and support departments; technical experts from the IT department; physical and IT security personnel with BCP skills; legal representatives familiar with corporate legal, regulatory, and contractual responsibilities; and representatives from senior management. Additional team members depend on the structure and nature of the organization.
Know the legal and regulatory requirements that face business continuity planners. Business leaders must exercise due diligence to ensure that shareholders' interests are protected in the event disaster strikes. Some industries are also subject to federal, state, and local regulations that mandate specific BCP procedures. Many businesses also have contractual obligations to their clients that they must meet before, during, and after a disaster.
Explain the steps of the business impact analysis process. The five stages of the business impact analysis process are the identification of priorities, risk identification, likelihood assessment, impact analysis, and resource prioritization.
Describe the process used to develop a continuity strategy. During the strategy development phase, the BCP team determines which risks they will mitigate. In the provisions and processes phase, the team designs mechanisms and procedures that will mitigate identified risks. The plan must then be approved by senior management and implemented. Personnel must also receive training on their roles in the BCP process.
Explain the importance of comprehensively documenting an organization's business continuity plan. Committing the plan to writing provides the organization with a written record of the procedures to follow when disaster strikes. It prevents the “it's in my head” syndrome and ensures the orderly progress of events in an emergency.
