FRAME SELECTION (CH 2)
19
FRAME — INTRODUCTION • Everything is becoming more complex; a frame (or framework)
helps tease out the most important factors to consider
• Having a process to deliberately identify the relevant framework helps avoid many well-known human biases
• Action basis
• Gut-based thinking (Type I thinking)
• “Hammer looking for a nail” — the “default” frame 20
FRAME — EXAMPLES • Key to a successful framework is to identify 2 to 3
critical factors among the many in a complex system
• Most frames end up being a 2 by 2 or 3 by 3 matrix (both with two factors)
• Ansoff matrix, BCG matrix, Porter’s 5 forces
• Personal decision frames 21
FRAMES — ANSOFF MATRIX
• Products and markets
• Existing and new
22
FRAMES — BCG
• Profitability
• Growth
23
FRAMES — FINANCIAL RISK FRAMEWORK
• Capital and liquidity
• Severity of environment
24
FRAMES — PERSONAL DECISIONS

FAILURE MODE AND EFFECT ANALYSIS
(CH 2)
26
FMEA — TERMINOLOGY • Broadly speaking, a risk assessment attempts to identify key risk
factors and their potential impacts
• Risk assessments range from enterprise in scale (company’s annual top risk assessment; CCAR for large banks; ORSA by insurance companies) to focusing on a particular project or initiative. FMEA is the latter
• Risk assessments can be performed by second-line of defense, or by the first-line, which is often called RCSA (Risk and Control Self Assessment)
27
FMEA — KEY STEPS • Identify risk factors (“failure modes”)
• Probability of adverse events occurring (“occurrence”)
• Impact of such occurrences (“severity”)
• Mitigating mechanisms and controls (“control”)
• Likelihood of detection (“detection”)
• A risk score summarizes these metrics into one number
• Risk Priority Number (RPN) is such an example
• Best practices identify a “gross” or “inherent” risk metric (before mitigation and controls), and a “net” metric (after mitigation and controls)
28
FMEA — QUANTITATIVE VS QUANTITATIVE
• FMEA dealing with processes and people (so-called “non-financial” risks) is inherently qualitative
• There is more art than science in assigning quantitative metrics to occurrences, severity, detection and so on
• Use simple 1-5 or 1-10 scales to avoid false precision and promote good dialogue
• As much as possible, relate the scales to much better defined performance metrics (such as lost revenue, lost income, stock price declines)
• Beware of inherent human biases; institute a robust “challenge” process from SMEs
29
FMEA — CONTROLS AND MITIGATION
• Preventive measures
• Mandatory checklists (for complex systems, the human mind is simply not reliable enough)
• Redundancy checks
• Pre-release regression testing
• Pre-release stress testing
• Training
• Detection measures
• Sampling and testing
• Early warning system (EWS) and risk reports

EARLY WARNING SYSTEM (CH 4)
31
EWS — FORECASTING MODELS
• Forecasting models identify key factors, and relate these factors to predicted outcomes
• Altman’s Z-Score model assesses possibilities of company defaults by linearly combining 5 observable metrics, such as level of capital and earnings power
• Data science uses generally statistical and machine-learning techniques to “mine” large volumes of data for signals
• These analytical tools often require standardized data and sophisticated modeling resources that are out of reach
32
EWS — CAUSAL FORECASTS • A causal forecast uses expert judgment to identify leading indicators
(causes) and effects or outcomes, i.e., lagging indicators
• Leading and lagging indicators are related by “connectors”, often a ratio of the two
• A systematic mechanism to keep track of actual realizations of these indicators to expected levels, fine-tuning and adjusting the model along the way
• It is also important to identify key assumptions, and track if these assumptions remain valid
33
EWS — DASHBOARD • It’s important to design a clear and concise report containing these key
leading and lagging indicators, essentially a risk dashboard for senior managers
• Many, if not most, of the data-driven risk reports and dashboards are ineffective:
• Too much information
• Too much false precision
• Key information buried with all other data
• Lack of trend analysis
