Simplification Cascades
Find one insight eliminating multiple components. "If this is true, we don't need X, Y, Z."
Core Principle
Everything is a special case of... collapses complexity dramatically.
One powerful abstraction > ten clever hacks.
When to Use
| Symptom | Action |
|---|---|
| Same thing implemented 5+ ways | Abstract the common pattern |
| Growing special case list | Find the general case |
| Complex rules with exceptions | Find rule with no exceptions |
| Excessive config options | Find defaults working for 95% |
The Pattern
Look for:
- Multiple implementations of similar concepts
- Special case handling everywhere
- "We need to handle A, B, C, D differently..."
- Complex rules with many exceptions
Ask: "What if they're all the same thing underneath?"
Examples
Example 1: Stream Abstraction
- Before: Separate handlers for batch/real-time/file/network data
- Insight: "All inputs are streams - just different sources"
- After: One stream processor, multiple stream sources
- Eliminated: 4 separate implementations
Example 2: Resource Governance
- Before: Session tracking, rate limiting, file validation, connection pooling (all separate)
- Insight: "All are per-entity resource limits"
- After: One ResourceGovernor with 4 resource types
- Eliminated: 4 custom enforcement systems
Example 3: Immutability
- Before: Defensive copying, locking, cache invalidation, temporal coupling
- Insight: "Treat everything as immutable data + transformations"
- After: Functional programming patterns
- Eliminated: Entire classes of synchronization problems
Process
- List variations - What's implemented multiple ways?
- Find essence - What's the same underneath?
- Extract abstraction - What's the domain-independent pattern?
- Test fit - Do all cases fit cleanly?
- Measure cascade - How many things become unnecessary?
Red Flags
Signs you're missing a cascade:
- "Just need to add one more case..." (repeating forever)
- "These are similar but different" (maybe they're the same?)
- Refactoring feels like whack-a-mole (fix one, break another)
- Growing configuration file
- "Don't touch that, it's complicated" (complexity hiding pattern)
Success Metrics
- 10x wins, not 10% improvements
- Measure in "how many things can we delete?"
- Lines of code removed > lines added
- Configuration options eliminated
- Special cases unified
Remember
- The pattern is usually already there, just needs recognition
- Valid cascades feel obvious in retrospect
- Test with "can this handle all existing cases?"
- Document the insight for future reference
