Planning Guidance
When Estimating
- Apply multiplier to core work
- Add bottleneck time at ×1.0
- Factor approval cycles (human response latency)
- Buffer 20% for unexpected iteration
Success Predictors
| Good Sign |
Bad Sign |
| Clear "done" definition |
Vague scope |
| Quick win potential |
External dependencies |
| Daily incremental work |
Big-bang delivery |
| Defined acceptance criteria |
"We'll know it when we see it" |

Anti-Patterns
❌ Instant everything — Testing and approval take real time
❌ Skip review — Speed without quality is waste
❌ Ignore iteration — First attempt isn't always right
❌ Forget context — Reading workspace takes time
❌ No buffer — Edge cases and clarifications happen
