Use this document to identify what and whom your organization may rely on to perform critical processes. In other words, if these resources were unavailable, it would be difficult or impossible to perform critical processes. Consider skilled personnel, specialized equipment, a specific environment, or critical vendors. More complex processes may require multiple resources. Remember that others are also depending on you. Be sure to document upstream dependencies in a separate section or version of this form. Once all dependencies are documented, you can make plans to mitigate the risks should they experience a disruption (e.g., alternate suppliers or workarounds). Document the resource dependencies for each critical process using this dependency mapping tool.
