A business impact analysis (BIA) is a process that identifies and assesses the effects that accidents, emergencies, disasters, and other unplanned, negative events could have on a business. The BIA (sometimes also called business impact assessment) predicts how a business will be affected by everything from a hurricane to a labor strike1.
One of the data that would be used when performing a BIA is the expected costs for recovering the business.
This data can help to estimate the amount of resources and funds that would be needed to restore the normal operations and functions of the business after a disruption. The expected costs for recovering the business can include:
The costs of repairing or replacing damaged or lost assets, such as equipment, inventory, or facilities The costs of hiring or training additional staff, or outsourcing some tasks or services The costs of implementing alternative or backup systems or processes, such as cloud computing or manual procedures The costs of communicating and coordinating with customers, suppliers, partners, regulators, and other stakeholders The costs of complying with legal or contractual obligations, or paying fines or penalties The costs of mitigating or preventing further losses or damages, such as insurance premiums or security measures23 The expected costs for recovering the business can help to determine the priority and urgency of the recovery activities, and to allocate the available resources and funds accordingly. The expected costs for recovering the business can also help to evaluate the cost-effectiveness and feasibility of the recovery strategies and options, and to justify the investment in the business continuity planning and management4.
The other options are not the data that would be used when performing a BIA, but rather the data that would be used for other purposes or processes. A cost-benefit analysis of running the current business is a data that would be used to compare the advantages and disadvantages of different business decisions or alternatives, such as launching a new product or service, or expanding to a new market. A cost-benefit analysis can help to assess the profitability and viability of the current business, but it does not measure the impact of a disruption on the business5. A cost of regulatory compliance is a data that would be used toestimate the amount of resources and funds that would be required to meet the rules and standards set by the authorities or agencies that govern the business, such as laws, regulations, or policies. A cost of regulatory compliance can help to ensure the legality and accountability of the business, but it does not measure the impact of a disruption on the business. A projected impact of current business on future business is a data that would be used to forecast the potential outcomes and consequences of the current business activities or strategies on the future business performance and growth, such as sales, revenue, market share, or customer satisfaction. A projected impact of current business on future business can help to plan and optimize the future business, but it does not measure the impact of a disruption on the current business.

Reviewing the risk register is the best way to help an organization gain insight into its overall risk profile, because it provides a comprehensive and structured representation of all the key risks that the organization faces, along with their likelihood, impact, and response strategies. A risk register is a tool that records and tracks the current status of risks, their sources, causes, consequences, and controls. A risk register helps to facilitate the communication and reporting of risks, and to support the risk-based decision making and prioritization. A risk profile is a summary of the key risks that an organization faces, and their implications for the organization's objectives and strategy. Reviewing the risk register is the best way to understand the risk profile, as it reflects the nature and level of exposure that the organization has from the various risk sources and scenarios. Reviewing the threat landscape, the risk appetite, and the risk metrics are all useful ways to help an organization gain insight into its overall risk profile, but they are not the best way, as they do not provide a comprehensive and structured view of the risks and their responses.

A primary function of the risk register is to provide supporting information for the development of an organization's risk profile, which is a comprehensive and structured representation of the risks that the organization faces. The risk profile helps the organization to understand its risk exposure, appetite, and tolerance, and to align its risk management strategy with its business objectives and context. The risk register is a document that records and tracks the identified risks, their causes, impacts, likelihood, responses, owners, and status. The risk register is an essential input for creating and updating the risk profile, as it provides the data and analysis of the risks that need to be prioritized and addressed. The other options are not the primary function of the risk register, although they may be related to it. The risk strategy is the plan and approach for managing the risks, and it is based on the risk profile. The risk process is the set of activities and tasks for identifying, assessing, responding, and monitoring the risks, and it is facilitated by the risk register. The risk map is a graphical tool for displaying the risks based on their impact and likelihood, and it is derived from the risk register.

Appropriate resources contribute most to the effective implementation of risk responses. Resources include people, time, money, equipment, and materials that are needed to execute the risk responses. Without appropriate resources, the risk responses may not be implemented properly, timely, or efficiently, and may not achieve the desired outcomes. The other options are not as important as appropriate resources, as they are related to the understanding, comparison, or documentation of the risk responses, which are less critical than the execution of the risk responses.

The most important factors to consider when evaluating a number of potential controls for treating risk are the residual risk and the cost of control. Residual risk is the risk that remains after the implementation of the controls. Cost of control is the amount of resources and efforts required to implement and maintain the controls. By considering the residual risk and the cost of control, the organization can optimize the balance between the risk exposure and the control investment, and choose the most effective and efficient controls.
Risk appetite and control efficiency, inherent risk and control effectiveness, and risk tolerance and control complexity are other possible factors, but they are not as important as residual risk and cost of control.
