| **Competition** | New entrant takes 20% share | Stable competition | Competitor exits market |
| **Regulation** | Restrictive new regulation | Status quo | Deregulation/favorable policy |
| **Technology** | Disruption makes product obsolete | Incremental improvement | Breakthrough advantage |
| **Funding** | Cannot raise next round | Raise at expected terms | Oversubscribed round |

```

### Two-Variable Sensitivity (Tornado Chart Data)

```
TORNADO CHART DATA — NET INCOME SENSITIVITY:

Variable            | Low Value | High Value | Low Impact  | High Impact
Revenue growth      | 5%        | 25%        | -$500K      | +$800K
Customer churn      | 8%        | 2%         | -$400K      | +$300K
COGS margin         | 45%       | 35%        | -$350K      | +$350K
Headcount           | +15       | +5         | -$300K      | +$200K
Interest rates      | 7%        | 4%         | -$150K      | +$100K
FX rates            | -10%      | +5%        | -$120K      | +$60K

  - Focus risk mitigation on top 3 variables
  - Variables below $100K impact are noise

## Monte Carlo Simulation Design

### Simulation Framework

```
MONTE CARLO SETUP:

STEP 1: IDENTIFY VARIABLES
  List all uncertain inputs that affect the outcome.
  For each variable, define:
    - Distribution type (normal, uniform, triangular, lognormal)
    - Parameters (mean, std dev, min, max)

STEP 2: DEFINE DISTRIBUTIONS
  Revenue growth:   Normal(mean=15%, std=5%)
  Customer churn:   Triangular(min=2%, mode=5%, max=12%)
  COGS margin:      Uniform(min=30%, max=45%)
  Headcount growth: Discrete([5, 8, 10, 12, 15], probs=[0.1, 0.2, 0.4, 0.2, 0.1])

STEP 3: RUN SIMULATIONS
  Iterations: 10,000 (minimum for stable results)
  For each iteration:
    1. Sample random value from each distribution
    2. Calculate outcome (revenue, profit, cash flow)
    3. Store result

STEP 4: ANALYZE RESULTS
  Mean outcome:           $______
  Median outcome:         $______
  Standard deviation:     $______
  5th percentile (VaR):   $______ (worst 5% of outcomes)
  95th percentile:        $______ (best 5% of outcomes)
  Probability of loss:    _____%
  Probability of target:  _____%

STEP 5: INTERPRET
  "There is a 90% probability that net income will fall between
   $______ and $______, with an expected value of $______."
```

### Distribution Selection Guide

| Variable Type | Recommended Distribution | Parameters | When to Use |
|--------------|------------------------|------------|-------------|
| **Growth rate** | Normal | Mean, Std Dev | Symmetric uncertainty |
| **Market size** | Lognormal | Mean, Std Dev | Right-skewed, can't be negative |
| **Project cost** | Triangular | Min, Mode, Max | Expert estimates with bounds |
| **Binary events** | Bernoulli | Probability | Will/won't happen (regulation, deal) |
| **Time to event** | Exponential | Rate | Customer lifetime, time to churn |
| **Counts** | Poisson | Rate | Number of events in a period |

## Cash Flow Stress Testing

### Runway Calculator

```
CASH RUNWAY ANALYSIS:

Current cash:           $______
Monthly burn rate:      $______
Monthly revenue:        $______
Net monthly cash flow:  $______ (revenue - burn)

SCENARIO RUNWAYS:
  Current trajectory:   ______ months
  If revenue drops 20%: ______ months
  If revenue drops 50%: ______ months
  If revenue goes to 0: ______ months (pure burn runway)

TRIGGER POINTS:
  6-month runway remaining: Begin fundraise / cut costs
  3-month runway remaining: Emergency cost reduction
  1-month runway remaining: Wind-down planning

COST REDUCTION LEVERS (by impact):
  Lever                    | Monthly Savings | Feasibility
  Freeze hiring            | $______         | High
  Reduce marketing 50%     | $______         | Medium
  Renegotiate vendor terms  | $______         | Medium
  Reduce headcount 10%     | $______         | Low (last resort)
  Eliminate office space    | $______         | Medium
```

## Scenario Planning Process

### Workshop Format

```
SCENARIO PLANNING WORKSHOP:

PHASE 1: IDENTIFY UNCERTAINTIES (30 min)
  - List all factors that could impact the plan
  - Rate each: Impact (1-5) x Uncertainty (1-5)
  - Select top 2 with highest combined score
  - These become the axes of your scenario matrix

PHASE 2: BUILD SCENARIOS (45 min)
  Using the 2x2 matrix:

            Factor A: Low          Factor A: High
  Factor B:
  High      Scenario 1:            Scenario 2:
            [Name and narrative]    [Name and narrative]

  Factor B:
  Low       Scenario 3:            Scenario 4:
            [Name and narrative]    [Name and narrative]

PHASE 3: MODEL FINANCIALS (60 min)
  For each scenario:
  - Revenue projection (12-36 months)
  - Cost structure changes
  - Cash flow impact
  - Key metrics (CAC, LTV, margins)

PHASE 4: DEVELOP STRATEGIES (45 min)
  For each scenario:
  - What would we do differently?
  - What early warning signals would we see?
  - What decisions should we make now?
  - What options should we preserve?

PHASE 5: ACTION PLAN (30 min)
  - "No regret" moves (good in all scenarios)
  - Contingency triggers and responses
  - Monitoring dashboard design
  - Review cadence (quarterly recommended)
```
