Our greatest glory is not in never falling, but in rising every time we fall.
Confucius
In a November post, I talked about a different way for a community to visualize its resilience. It was a functional approach focusing on three aspects of a community – its common functions, the risks it faces, and the resources it has for recovery. Left hanging was how a community can determine the resources needed for recovery from a disaster – and whether it can recover at all.
Recently, my co-worker Jennifer Adams and I were notified that our paper that provides one approach communities can use has been accepted for publication. The approach is based on the stress testing performed by financial institutions, adapted for the community context. I briefly summarize the approach below; if you are interested in more detail, it will be in the published version (in the Journal of Homeland Security and Emergency Management).
In general, the approach is effectively an extended tabletop exercise, focused on a specific event. It is intended to be scalable – applicable to a neighborhood, a community system, or an entire community. Since the focus is on recovery, the time frame for the scenario extends beyond that usually considered in emergency management exercises.
The approach starts with development of a scenario based on a specific extreme event. The extreme event chosen should correspond to one or more of the risks facing the community. Each scenario should be plausible but need not be tremendously detailed. The type and magnitude of the extreme event, its geographic scope if relevant (e.g., areas of flooding or damage) and the time over which the event will occur should be included.
Perhaps in parallel, the scope of testing is also fixed. Again, this may be a neighborhood, a single community system or an entire community. Since it is assumed that testing is conducted by those who know the neighborhood, system or community, the availability of these “subject matter experts” effectively determines the scope of testing.
An important part of the approach is the establishment of success criteria: this forces the community to think about what recovery is, and how long it should take to reach it. This in turn sets the minimum time horizon for testing – the recovery process should be simulated at least this long (and if recovery has not occurred by this time, the test can be extended). For many physical infrastructure systems, success criteria for recovery may already have been set (e.g., Maximum Allowable Outages); for others (e.g., social support systems), a desired time to resume normal operations may be used.
The next step is focused on the impacts of the extreme event. The community’s anticipated losses – especially in terms of the community’s fixed assets – are determined. This includes both the direct losses, and those indirect ones that result either as a cascade because of interdependencies or because of actions taken in response to the extreme event. So, for example, a weather event triggers physical damage, that in turn challenges the community’s human, economic and social capital. A health crisis may cause loss of life; as we have seen with Covid-19, the response to the pandemic may seriously deplete the community’s social and economic capital as well. Social unrest can lead to loss of life as well as tears in the community’s social and cultural fabrics. As a result of this analysis, metrics for measuring progress toward recovery are also developed.
With recovery – the end state – defined, and the losses identified, the next step is to identify the tasks required to achieve recovery. This is the core of the approach – first identifying the tasks and then the resources needed to accomplish each task. If a community has a long-term recovery plan, this is an opportunity to exercise it. Since most communities do not have such plans, this forces them to think beyond their desired endpoint and to detail how they’re going to get there after the extreme event. In effect, it provides an opportunity to develop a recovery plan for the specific extreme event. Most likely, these plans will represent “brute force” approaches.
In this step, the community also goes one step further – looking at the time necessary to accomplish each task with the resources available. It uses the community capitals approach as a means to systematically look at the assets available for recovery (dispatchable capital) and the time required to deploy them successfully. Depending on the expertise available for the test, rather accurate estimates of task duration and sequencing (serial and parallel) can be achieved.
The final step is to analyze the results. First and foremost is to determine whether the success criteria have been met. In other words, determining whether all of the tasks required for recovery can be completed in the expected/desired time frame. If they cannot, then the testing points to possible actions the community can take to recover in time. These may be mitigating actions to limit losses; investments to increase dispatchable assets; better planning to develop more innovative (and probably more elegant) paths to recovery. In practice, it’s likely that a combination of some or all of these would be chosen. This approach to testing also provides a time to recovery (i.e., when the last task is completed).
Stress testing of this type offers some real positives to a community:
• It is based on the risks the community actually faces.
• It uses the community’s own expertise and knowledge of itself.
• It is scalable – a community can look at only one part or the whole community.
• It provides a time to recover based on the resources actually available to the community.
• It indicates opportunities for community action to reduce the time to recovery.
I have briefly summarized the approach and what it can do for a community. In a followup, I will look at a specific scenario based on a health crisis. I’ll do this in two ways: first, just looking at a community health care system, and then looking at the entire community. I’ll do this with much trepidation – the damage from covid is perhaps too fresh; too many are still falling ill and some dying; and, sadly, too many are still playing the Blame Game. But I’ll still do it, because as Confucius indicates, the glory is in rising again – recovering – and stress testing can speed our rise from disaster.
