> ==Risk Assessment== is the analysis of uncertain future events.
## Risk Assessment Techniques
There are two broad categories of risk assessment techniques:
| Technique | Description |
| -------------------------------- | ----------------------------------------------------------------------------------- |
| **Quantitative risk assessment** | Analyzes quantitative data about events with tools like statistics. |
| **Qualitative risk assessment** | Analyzes situations and outcomes with tools like words, logic, and categorization. |
### Risk Identification
> Risk identification is the process of seeing, naming, and categorizing a risk.
| Risk Identification | Description |
| --------------------------------------------- | ----------------------------------------------------------------------------------------------- |
| [[Cynefin Framework]] | Process to make sense of a situation with uncertainty. |
| [[Cindynic Approach]] | Identify value-aligned actions towards goals and purposes. |
| [[Risk Management Policy]] | Specify how your organization responds to and controls risk. |
| [[Risk Appetite\|Risk Appetite Statement]] | Specify "Do and Don'ts": how much risk the organization is willing to take. |
| [[Risk Taxonomy]] | Give each risk a name and classification according to its characteristics. |
| [[Scenario Analysis]] | Explore future events by analyzing alternative possible outcomes. |
| [[Structured What-If Technique (SWIFT)]] | Structured brainstorming with prompts. |
| [[Failure Modes and Effects Analysis (FMEA)]] | Review all system components to identify potential failure modes, and their causes and effects. |
| [[Risk Register]] | Documents risks in a register with owners and controls. |
### Risk Analysis
> Risk Analysis is the systematic process to comprehend the nature of risk by seeking new knowledge.^[[[Society for Risk Analysis Glossary]]]
| Technique | Description |
| -------------------------------------- | -------------------------------------------------------------------- |
| [[Scientific Method]] | Establish facts through experimentation and observation. |
| [[MECE Principle]] | Break down a problem into its component parts. |
| [[Bayesian Analysis]] | Update the probability of hypotheses by evaluating facts. |
| [[Bow-Tie Analysis]] | Visualize causes and consequences of risk in a diagram. |
| [[Exploratory Data Analysis (EDA)]] | Explore the structure and nature of your data. |
| [[Markov Analysis]] | Predicts future system states using probabilities of current states. |
| [[Simulation\|Monte-Carlo Simulation]] | Generate simulated outcomes using random variables. |
### Risk Measurement
> Risk measurement is the process of assigning a number to an event. A **risk measure** is a mapping from a set of random variables to the real numbers.^[[Wikipedia - Risk Measures](https://en.wikipedia.org/wiki/Risk_measure)]

| Risk Measure | Description |
| --------------------------------- | ----------------------------------------------------------------------------------- |
| [[Variance]] / Standard Deviation | The dispersion of data points around the average. |
| [[Beta Coefficient]] | Systemic risk in a financial portfolio relative to the market. |
| [[Sharpe Ratio]] | Risk-adjusted return, calculated as the excess return per unit of risk. |
| [[Loss Frequency]] | The chance of an event occurring, often expressed as a percentage or probability. |
| [[Loss Severity]] | The extent of damage or impact an event might cause. |
| [[Expected Loss (EL)]] | The average loss, calculated as Probability x Impact |
| [[Value at Risk (VaR)]] | The maximum expected loss over a specified time period at a given confidence level. |
| [[Tail Value at Risk (TVaR)]] | The expected loss beyond the VaR threshold, focusing on tail risk. |
| [[Key Risk Indicator]] | Operational metrics used to monitor risk levels and provide early warning signals. |
