Risk Mgmt Unit 2: Cascading Risks: Workflows for Risks

Learn to identify and evaluate cascading risks and causal chains is the goal of this unit, with easy-to-use tools for creating flow charts and maps for analysis and decision-making.
• Determine the data you need to understand systemic risks
• Identify the relationships that lead to cascading risks
• Discuss ways do develop workflows of flows of risks
• Identify the locations most likely to trigger cascading failures
• Identify the types of risks associated with the failures
• Describe methods of analyzing cascading risks using several analytical techniques
• Explain how a Bayesian analysis can be effective for identifying relationships

Scenario 2:  Cascading Risks:  Workflows for Risks
Joseph works for Wolf Midstream, which recently diversified into solar and wind energy to generate electricity for the grid in northeastern Texas and southwest Arkansas. 

Things have been going well.  However, the weather forecast says there is a high likelihood of a tornado outbreak near their solar panel farm and also near the Wolf wind farm. Wolf Midstream is connected with Lone Wolf Electric, which owns transmission lines into the small towns and rural homes.

The leadership of Wolf wants a report that provides 3 different scenarios for different levels of storms.  They want to know what all the potential impacts will be, and how they will affect each other.

Your Task: Help Joseph develop a map that shows how damage in one place will affect other places, resulting in causal chains, and cascading failures.

What will Joseph need?
 Which data does she need to collect?
 What kind of maps should she build?
 Use a diagram to show with arrows the cascading failures.
 Then, mark on a map where the problems will occur (after you’ve completed the diagrams).

You may wish to create 4 different maps:
 Stage 1: Initial impact
 Stage 2:  Secondary impact
 Stage 3:  What happens after Stage 2 failures occur
 Stage 4:  Final level of outcomes (long-term consequences).
