# Alex Effort Estimation

> Convert human developer estimates to AI-assisted timelines.

**Last Updated**: April 2026

---

## Quick Reference: Effort Units

| Unit | Time | Use For |
|------|------|---------|
| **⚡ Instant** | < 5 min | Single edit, lookup, generation |
| **🔄 Short** | 5-30 min | Multi-file change, docs, skill |
| **⏱️ Medium** | 30-60 min | Feature, test suite, debugging |
| **📦 Session** | 1-2 hours | Major feature, release |
| **🗓️ Multi-session** | 2+ hours | Large refactor, new system |

---

## Conversion Table

| Task Type | Human → Alex | Multiplier |
|-----------|--------------|------------|
| **Research** | 8h → 45m | ×0.10 |
| **Code generation** | 4h → 35m | ×0.15 |
| **Documentation** | 4h → 25m | ×0.10 |
| **Skill creation** | 2h → 15m | ×0.12 |
| **Refactoring** | 4h → 1h | ×0.25 |
| **Bug fix (known cause)** | 2h → 35m | ×0.30 |
| **Bug fix (unknown)** | 4h → 2h | ×0.50 |
| **Architecture design** | 8h → 2h | ×0.25 |
| **Test writing** | 4h → 1.5h | ×0.40 |
| **New feature (S)** | 4h → 1h | ×0.25 |
| **New feature (M)** | 2d → 3h | ×0.20 |
| **New feature (L)** | 1w → 6h | ×0.15 |
| **Release process** | 4h → 1h | ×0.25 |

**Formula**: `Alex Time = Human Estimate × Multiplier + Bottlenecks`

## What Accelerates (4-10×)

| Activity | Why Fast |
|----------|----------|
| Research | Semantic search vs browsing |
| Boilerplate | Generated, not typed |
| Multi-file edits | Parallel in one pass |
| Code review | Instant pattern recognition |
| Learning new tech | Bootstrap learning skill |
| Documentation | Generated from code/context |

---

## Bottlenecks (Cannot Accelerate)

These take real time regardless of AI:

| Bottleneck | Impact | Mitigation |
|------------|--------|------------|
| **Test execution** | ×1.0 | Parallelize, fast feedback loops |
| **Build/compile** | ×1.0 | Incremental builds, caching |
| **Human approval** | Variable | Batch decisions, async review |
| **External APIs** | Variable | Mock for dev, timeout handling |
| **CI/CD pipeline** | ×1.0 | Optimize pipeline, parallel jobs |
| **Context loading** | ×0.8 | Pre-read relevant files |

## Estimation Template

```markdown
| Task | Human Est. | Alex Est. | Bottleneck |
|------|------------|-----------|------------|
| [Task] | [Xh/d] | [⚡🔄⏱️📦🗓️] | [None/Test/Approval/Build] |
```

**Example**:

| Task | Human | Alex | Bottleneck |
|------|-------|------|------------|
| Add new API endpoint | 4h | 🔄 30m | None |
| Write integration tests | 3h | ⏱️ 1.5h | Test execution |
| Deploy to staging | 2h | 📦 1.5h | CI pipeline |
| Code review cycle | 2h | ⏱️ 2h | Human approval |
| **Total** | **11h** | **📦 5.5h** | - |

---

## Planning Guidance

### When Estimating

1. **Apply multiplier** to core work
2. **Add bottleneck time** at ×1.0
3. **Factor approval cycles** (human response latency)
4. **Buffer 20%** for unexpected iteration

## Calibrated from 62-Project Retrospective

### What Accelerates Well (4-10×)

| Task Type | Human | Alex | Factor | Evidence |
|-----------|-------|------|--------|----------|
| Documentation | 4h | 25m | 10× | METHODOLOGY doc: 400 lines in ~30 min |
| Skill creation | 2h | 15m | 8× | 65 skills created, many in single sessions |
| Code generation | 4h | 30m | 8× | Slash commands, refactors |
| Research + synthesis | 8h | 45m | 10× | 62 project analysis in ~20 min |
| Architecture decisions | 8h | 2h | 4× | Root cause analysis + recommendations |

### What Doesn't Accelerate (<2×)

| Bottleneck | Why | Evidence |
|------------|-----|----------|
| External dependencies | Can't control | CookProject blocked by book formatting |
| Unrealistic scope | Must be discovered | Altman-Z-Score, KalabashDashboard |

### Example: v4.2.5 Release Retrospective

| Task | Human Est. | Actual Alex | Bottleneck |
|------|------------|-------------|------------|
| Update engine to 1.109 | 30m | ⚡ 5 min | None |
| Consolidate 9→3 agents | 4h | 🔄 20 min | None |
| Create 6 slash commands | 2h | 🔄 15 min | None |
| Refactor dream to shared | 4h | ⏱️ 45 min | Testing |
| Test all features | 2h | ⏱️ 1h | Human testing |
| Release process | 4h | 📦 1h | CI/approval |
| **Total** | **16.5h** | **📦 2.5h** | - |

**Acceleration factor: 6.6×**

### 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" |

### Scope Guidance

| Alex Estimate | Scope Health |
|---------------|--------------|
| ⚡ Instant | Perfect — ship it |
| 🔄 Short | Good — single session |
| ⏱️ Medium | OK — plan breaks |
| 📦 Session | Consider splitting |
| 🗓️ Multi-session | **Split required** |

## 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
