Which two dependencies are validated by Business Impact Analysis? (Choose two)

The Business Impact Analysis (BIA) is a fundamental process within ISO 22301 used to analyze the impact of a disruption on an organization's activities. A core component of this analysis is identifying the resources and dependencies required to deliver products and services. This explicitly includes mapping dependencies between internal processes and activities (Internal Dependencies) as well as dependencies on external entities such as suppliers, utility providers, and outsourced partners (External Dependencies). Validating these dependencies is crucial for understanding the full scope of potential impacts and for establishing realistic recovery time objectives (RTOs).

C. Static Dependencies: This term is not a standard classification within the ISO 22301 BIA framework; the focus is on the organizational source (internal/external) of the dependency.
D. Dynamic Dependencies: Similar to static dependencies, this is not a primary BIA classification. The BIA process categorizes dependencies by their relationship to the organization's boundaries.

1. ISO 22301:2019, Security and resilience — Business continuity management systems — Requirements, Clause 8.2.2: This clause on Business Impact Analysis requires the organization to "identify dependencies and supporting resources for prioritized activities, including... suppliers and partners...". This directly addresses external dependencies and implies the analysis of inter-process relationships, which are internal dependencies.

2. ISO 22313:2020, Security and resilience — Business continuity management systems — Guidance on the use of ISO 22301, Clause 8.2.2.3: This guidance document explicitly clarifies the BIA process. It states that an organization should identify "dependencies on other activities (internal or outsourced)" and "dependencies on external organizations (e.g. suppliers, distributors)". This directly supports the validation of both internal and external dependencies.

Chapter 6, "Operation," Section "Business impact analysis (BIA)": This guide, aligned with the standard, explains that the BIA process involves identifying "the dependencies between business processes, both internal and external, and the resources required to operate the processes." (Paraphrased from concepts in the chapter discussing BIA inputs and outputs).
