# 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
|
|
|
|
1. **List variations** - What's implemented multiple ways?
|
|
2. **Find essence** - What's the same underneath?
|
|
3. **Extract abstraction** - What's the domain-independent pattern?
|
|
4. **Test fit** - Do all cases fit cleanly?
|
|
5. **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
