Tech Radar

ThoughtWorks 의 framework. 매 6 month, 매 tech 의 status (adopt / trial / assess / hold). Team 의 alignment + decision.

📖 핵심 개념

  • 매 quadrant: language / framework / tool / platform.
  • 매 ring: adopt / trial / assess / hold.
  • 매 6 month update.
  • Public 또는 internal.

💻 코드 패턴

4 ring

ADOPT:
- Production-proven.
- Team 가 default.
- 매 새 project.

TRIAL:
- 작은 production trial.
- Pilot project.
- 1-2 team.

ASSESS:
- 실험 가능.
- Watch carefully.
- Learn.

HOLD:
- 새 project 가 안 됨.
- 기존 = migrate plan.
- 매 새 use 가 justify.

4 quadrant

- Languages & Frameworks (TS, React, ...).
- Tools (Vite, ESLint, ...).
- Platforms (AWS, Cloudflare, ...).
- Techniques (TDD, microservice, ...).

예 (engineering team)

ADOPT:
- TypeScript
- React + Compiler
- Tailwind 4
- Postgres
- Vite
- Vitest

TRIAL:
- TanStack Start
- Cloudflare Workers
- Hono
- Bun
- DuckDB

ASSESS:
- SolidJS
- Qwik
- Effect-TS
- Compose Multiplatform
- Helix editor

HOLD:
- jQuery (legacy 만)
- Webpack (Vite migrate)
- Class component (functional 만)
- Sass (CSS modern)

Process

1. 매 6 month review.
2. 매 engineer 가 propose tech.
3. Discussion + vote.
4. Update radar.
5. Communicate (all-hands).
6. Implement (migrate plan if hold).

Internal radar

Company-specific.
- 매 team 의 input.
- Tech council 가 decide.
- Documented + searchable.

Public radar (ThoughtWorks)

thoughtworks.com/radar.
- 매 6 month update.
- Industry trends.
- 매 entry 의 reasoning.

→ Reference 만. Each company 가 own.

매 entry 의 doc

# React + Compiler

Status: Adopt
Quadrant: Languages & Frameworks
Updated: 2026-05-09

## Why
- Type-safe.
- Modern (auto memo).
- 큰 ecosystem.

## When
- All new web projects.
- Migrate Class component.

## When NOT
- 매우 작은 (Astro 가 더).
- Native mobile (RN OK).

## Reference
- [Decision: React vs Vue](#)

Migration (HOLD → ADOPT)

Old: Webpack (HOLD).
New: Vite (ADOPT).

Plan:
- New project: Vite (immediate).
- Old project: migrate over 6-12 month.
- Tooling support (build script, docs).
- Knowledge sharing (brown bag).

Conflict resolution

Engineer A: "Adopt SolidJS now".
Engineer B: "Hold, React 가 좋음".

Process:
- Pros / cons doc.
- Trial pilot (small project).
- 6 month 후 review.
- Decision based on data.

Tech debt 의 visibility

Hold = tech debt.
- 매 quarter 의 migration status.
- "이 5 codebase 가 Sass = migrate by Q4".
- Engineering metric.

Tech radar 의 가치

- Alignment (모든 사람 가 같은 tech 사용).
- Onboarding (새 사람 = radar 읽음).
- Decision (이 tech 가 OK?).
- Communication (manager 가 understand).

→ "Stack 가 무엇" 의 single source.

함정

- 매년 한 번만 update: stale.
- 매 month update: noisy.
- Engineer input 없음: top-down.
- Public 없음: 외부 candidate 가 모름.
- "Hold" 무시: migrate 안 됨.
- Hype-driven: adopt before stable.

Adoption curve

새 tech 의 lifecycle:
1. Innovator (early adopter).
2. Early majority.
3. Late majority.
4. Laggard.

→ Adopt 가 late majority 시점.
Trial 이 early majority.
Assess 가 early adopter.

매 company 의 radar

  • Spotify: golden path (preferred stack).
  • Atlassian: tech radar.
  • Zalando: 매 quarter 발표.
  • Netflix: paved road.

"Paved road" / "Golden path"

Tech radar 의 implementation.
- 1 stack 가 default.
- Tooling + doc + support.
- 매 deviation = justify.

→ "Innovation 의 cost ↓" + "Maintenance 의 share ↑".

vs ThoughtWorks Radar

Industry radar:
- General trend.
- 큰 picture.

Internal radar:
- Specific stack.
- Migrate plan.

→ 둘 다 사용. Internal 가 actionable.

Build / buy / open source

매 entry 의 추가 dimension:
- Build: 자체 build.
- Buy: SaaS / vendor.
- Open: open source.

→ Cost / control / community trade-off.

Risk assessment

매 tech 의:
- Maturity (new vs old).
- Community (small vs big).
- Vendor lock-in.
- Migration cost.
- Performance.
- Security history.

→ Multi-dimensional 결정.

Communication

- Quarterly all-hands: update.
- Wiki / Notion: searchable.
- Slack #tech-radar: discussion.
- 매 ADR 가 radar reference.

CTO / Architect 의 role

- Curator (의제, decision).
- Cross-team alignment.
- 외부 trend watch.
- Risk balance.

→ "What tech 가 우리 가 사용?" 의 answer.

🤔 의사결정 기준

상황 추천
큰 org Internal radar
작은 startup 1 stack (no radar)
Multi-team alignment Tech radar
New tech Assess / Trial
Migration Hold + plan

안티패턴

  • No radar: 매 team 가 다른 stack.
  • Stale radar: 1 year old.
  • Top-down only: engineer input X.
  • Hype-driven: unstable.
  • Hold 무시: 점진 fix X.
  • 모든 tech adopt: complexity.

🤖 LLM 활용 힌트

  • Adopt / Trial / Assess / Hold = 4 ring.
  • 매 6 month update.
  • Engineering decision 의 alignment.
  • Public (ThoughtWorks) 가 reference.
