Team Roles in BDR

BDR adoption involves multiple roles working together. This document defines the responsibilities of each role in the BDR ecosystem.

Roles Overview

Role	Primary Focus	Key Responsibilities
Automation QA (AQA)	Technical Implementation	Layer 0, Layer 1, Infrastructure
Manual QA / Business Analyst	Business Logic	Layer 3, Report Validation
Developer	Feature Development	Layer 2, Layer 1, Maintenance
Test Lead / Architect	Standards & Strategy	Methodology Enforcement, Coaching

---

Automation QA (AQA)

The technical backbone of BDR implementation.

Responsibilities

• Implement Layer 0 and Layer 1 — Technical implementation: Page Objects, API clients, database connectors.
• Maintain test frameworks and infrastructure — Parallel execution, CI integration, test environments.
• Ensure test stability and performance — Anti-flakiness strategies, debugging, optimization.
• Create reusable Flows — Atomic interactions that can be composed into Domain actions.

Key Artifacts

Layer	Artifact Type	Examples
Layer 0	Page Objects, API Clients	LoginPage, CartAPI (file extensions depend on the stack)
Layer 1	Flows	LoginFlow, CartFlow (file extensions depend on the stack)

---

Manual QA / Business Analyst

The bridge between business requirements and test specifications.

Responsibilities

• Define Layer 3 scenarios — Write test scenarios in pure business language.
• Collaborate with developers — Define Layer 2 domain actions that reflect business intent.
• Review Allure reports — Validate that test results match business expectations.
• Maintain traceability — Ensure test coverage maps to user stories and acceptance criteria.

Key Artifacts

Layer	Artifact Type	Examples
Layer 3	Scenarios	checkout_happy_path, auth_login (file extensions depend on the stack)
Layer 2	Domain Classes	Customer, Admin (implemented in the chosen programming language)

---

Developer

Contributor to test code as part of feature development.

Responsibilities

• Contribute to Layer 2 and Layer 1 — Implement domain actions and flows as part of feature work.
• Maintain test code alongside production code — Shared repositories, co-located test files.
• Use BDR reports for regression detection — Catch broken business logic during refactoring.
• Write tests for new features — Follow BDR patterns from the start.

Key Artifacts

Layer	Artifact Type	Examples
Layer 2	Domain Actions	Customer.addItemToCart()
Layer 1	Flows	CartFlow.confirmAddition()

---

Test Lead / Architect

The guardian of BDR standards and continuous improvement.

Responsibilities

• Define and enforce BDR standards — Code review guidelines, naming conventions, layer boundaries.
• Coach team members — Training sessions, pair programming, documentation.
• Drive continuous improvement — Analyze flakiness trends, optimize execution time, improve reporting.
• Align methodology across teams — Cross-team consistency, shared patterns, knowledge sharing.

Key Artifacts

Type	Examples
Standards	CONTRIBUTING.md, Code review checklists
Metrics	Flakiness reports, Coverage dashboards
