Product Development Workflow 🚀
This guide covers product planning, development cycles, and release processes for Ultralytics products.
Product Philosophy 🎯
Core Principles
- Ship Fast, Learn Faster: 2-week iteration cycles, MVP-first approach
- User-Centric: Build features users request most, validate with data
- Open Source First: Public development, community feedback drives roadmap
- Performance is a Feature: Sub-ms inference times, minimal memory footprint
- API-First Design: Simple, intuitive APIs that developers love
Development Values
- Bias to action: Prototype in days, ship in weeks, not months
- Data-driven decisions: GitHub stars, PyPI downloads, Discord polls guide priorities
- Minimum Viable Product: Release 80% solution fast, iterate to 100%
- Continuous deployment: Main branch is always production-ready
- Radical transparency: Public roadmap, open metrics, community input
Feature Development Lifecycle 🔄
1. Discovery & Planning (Week 1)
Identify needs through:
- User feedback: GitHub issues (votes), Discord polls, community surveys
- Usage analytics: Feature adoption rates, API endpoint metrics, error logs
- Performance data: Benchmark results, inference times, memory usage
- Competitive analysis: Track competitor releases, market trends
- Internal dogfooding: Use our own tools, identify pain points
Evaluate against:
- User impact: How many users affected? Pain level (1-10)? Revenue impact?
- Technical feasibility: Engineering effort (S/M/L/XL)? Dependencies? Risks?
- Strategic alignment: Advances YOLO11 leadership? Supports key verticals?
- Resource availability: Team capacity? Competing priorities? Timeline?
- Competitive urgency: Will competitors ship first? Lock-in risk?
Output: Prioritized feature backlog with effort estimates and user impact scores
2. Design & Specification (Days 1-3)
For major features (>2 weeks engineering time):
- Design doc: Problem statement, proposed solution, alternatives considered, success metrics
- Technical spec: API design, architecture diagrams, data models, edge cases
- Success criteria: Quantitative metrics (speed, accuracy, adoption) and user feedback targets
- Risk assessment: Technical risks, dependencies, rollback plan
- Team review: Feedback from engineering, product, and key stakeholders
For small features (<1 week engineering time):
- GitHub issue: Clear problem description, proposed approach, acceptance criteria
- Quick discussion: 15-min sync with relevant engineers
- Go/No-go: Manager approval to proceed
Output: Approved spec with clear scope, success metrics, and timeline
3. Implementation (Sprint Execution)
Sprint planning (every 2 weeks):
- Sprint goal: One clear objective per sprint
- Task breakdown: Split features into <1 day tasks
- Capacity planning: Account for meetings, PR reviews, support
- Dependencies: Identify blockers, coordinate with other teams
Daily execution:
- Morning standup (15 min): Yesterday's progress, today's plan, blockers
- Focus time: 4-6 hours deep work, minimize meetings
- PR reviews: Review teammate PRs within 4 hours
- End-of-day updates: Slack progress update, move tickets
Development best practices:
- Feature flags: Deploy dark, enable gradually
- Test coverage: Write tests before shipping (>80% coverage target)
- Documentation: Update docs in same PR as code
- Performance: Benchmark before/after, no regressions
- Security: Run security scans, fix critical issues immediately
Follow detailed development workflow for PR process and code standards.
4. Review & QA (Parallel with Implementation)
Code review (required for all PRs):
- <24 hour response time: Senior engineers prioritize reviews
- Quality checks: Code correctness, test coverage, performance impact
- Security review: Automated scans + manual review for sensitive code
- Documentation: Verify docs updated, examples work
- Approval required: 1+ senior engineer approval before merge
QA process:
- Automated testing: Unit, integration, E2E tests run on every commit
- Manual testing: QA engineer validates key user flows
- Performance testing: Benchmark against baseline, flag regressions
- Cross-platform: Test on CPU, GPU, edge devices
- User acceptance: Beta test with select users for major features
Iteration cycle:
- Address feedback immediately, don't accumulate technical debt
- Re-test after changes, verify fixes don't break other features
- Update tickets with progress, keep stakeholders informed
5. Release & Launch
