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

| 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

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
