在评估一个组织的弹性，最终评估一个地区的弹性时，物理依赖是一个基本的考虑因素。每个组织都需要特定的资源来支持其运作。这些资源供应的中断可能严重影响业务连续性。在寻求减少一个组织受其他组织的使命、职能和运作直接影响的程度时，彻底描述依赖关系是很重要的。处理每个关键资源时的一般协议是确定资源的用途，是否有冗余服务提供该资源，以及采取何种保护措施、备份设备和安排来维持服务。最后，资源的重要性是通过估算一旦主要服务丢失，设施遭受严重影响所需的时间，以及在没有备用服务的情况下设施运营可以维持的百分比，以及确定是否有任何外部法规/政策到位，这些法规/政策由于缺乏关键资源而导致服务中断，需要关闭设施。所有这些信息都可以以交互式依赖曲线的形式呈现，这有助于预测和管理中断对关键资源供应的影响。
Physical dependencies are a fundamental consideration when assessing the resilience of an organisation and, ultimately, the resilience of a region. Every organisation needs specific resources for supporting its operations. A disruption in the supply of these resources can severely impact business continuity. It is important to characterise dependencies thoroughly when seeking to reduce the extent an organisation is directly affected by the missions, functions and operations of other organisations. The general protocol when addressing each critical resource is to determine the use for the resource, whether there are redundant services providing the resource, and what protections, backup equipment and arrangements are in place to maintain service. Finally, the criticality of the resource is determined by estimating the time it will take for the facility to experience a severe impact once primary service is lost and what percentage of facility operations can be maintained without backup service in place, as well as identifying whether any external regulations/policies are in place that require shutdown of the facility because of service disruption owing to lack of a critical resource. All of this information can be presented in the form of interactive dependency curves that help anticipate and manage the effect(s) of a disruption on critical resources supply.
