IN2 Premortem Analysis

Apply the IN2 Premortem Analysis transformation to assume failure has occurred and work backward to identify causes.

What is IN2?

IN2 (Premortem Analysis) Assume failure has occurred and work backward to identify causes.

When to Use IN2

Ideal Situations

  • Stress-test a plan by reversing assumptions
  • Identify risks by imagining failure states
  • Simplify outcomes by removing unnecessary elements

Trigger Questions

  • "How can we use Premortem Analysis here?"
  • "What changes if we apply IN2 to this risk assessment for a launch?"
  • "Which assumptions does IN2 help us surface?"

The IN2 Process

Step 1: Define the focus

// Using IN2 (Premortem Analysis) - Establish the focus
const focus = "Assume failure has occurred and work backward to identify causes";

Step 2: Apply the model

// Using IN2 (Premortem Analysis) - Apply the transformation
const output = applyModel("IN2", focus);

Step 3: Synthesize outcomes

// Using IN2 (Premortem Analysis) - Capture insights and decisions
const insights = summarize(output);

Practical Example

// Using IN2 (Premortem Analysis) - Example in a risk assessment for a launch
const result = applyModel("IN2", "Assume failure has occurred and work backward to identify causes" );

Integration with Other Transformations

  • IN2 -> P1: Pair with P1 when sequencing matters.
  • IN2 -> DE3: Use DE3 to validate or stress-test.
  • IN2 -> SY8: Apply SY8 to compose the output.

Implementation Checklist

  • Identify the context that requires IN2
  • Apply the model using explicit IN2 references
  • Document assumptions and outputs
  • Confirm alignment with stakeholders or owners

Common Pitfalls

  • Treating the model as a checklist instead of a lens
  • Skipping documentation of assumptions or rationale
  • Over-applying the model without validating impact

Best Practices

  • Use explicit IN2 references in comments and docs
  • Keep the output focused and actionable
  • Combine with adjacent transformations when needed

Measurement and Success

  • Clearer decisions and fewer unresolved assumptions
  • Faster alignment across stakeholders
  • Reusable artifacts for future iterations
