Quality Coach Model

Vấn đề

QA team không scale với eng team. 1 QA: 10 dev common, but quality phải distribute.

Quality Coach role

QA senior who coach dev to test better. Not test executor anymore.

Activities

• Pair with dev on test design.
• Run lunch & learn (testing techniques).
• Review test code, give feedback.
• Author internal "testing handbook".
• Office hours: dev can ask testing questions.

Quality Champion (dev side)

1-2 dev per team volunteer as testing advocate.

• Attend QA monthly meetup.
• Spread best practice in team.
• Report quality concerns to QA Lead.

Org structure example

QA Lead
  ├── Quality Coach (3-5)
  │     ├── coach embedded with squad
  │     └── shared backlog quality initiatives
  └── SDET Platform team (5-10)
        └── build framework, infra
Engineering squads
  ├── 8 dev + 1 Quality Champion
  ├── 6 dev + 1 Quality Champion
  └── ...

Coach skills

• Strong technical depth.
• Influence without authority.
• Patience teaching.
• Documenter (write playbooks).

Anti-pattern

• Coach become helpdesk → no proactive work.
• Coach skip pairing → just review PR.
• No champions → coach burn out.

VN context
